Harmful Printed Circuit Board Effects 101

Designing a printed circuit board is not as easy as what you think of. There are several considerations to take into account. Since printed circuit boards are composed of one or more conductor patterns and insulating layers, some errors can happen in a circuit. These errors can be harmful to the performance of circuit.

Often, printed circuit board designers do not take into account the electrical characteristics of PCBs. This leads to degraded overall performance. Some of the dangerous PCB effects are spurious voltage drops, leakage resistances, dialectric absorption and stray capacitance.

Leakage Resistances

Printed Circuit BoardThe most common mistake that engineers do is considering all PCB traces and wires as resistors. These wire interconnections and trace resistances can cause harmful effects. Most engineers think that think that copper is a very strong conductor, but in reality it is not. The copper used in most PCBs has only resistance of 0.48 Ω/square which is not good enough.

PCB trace resistances become erroneous under unfavorable conditions. To avoid any problems with precision circuits you should utilize a heavier copper and create wider traces. The main key here is designing with intensive care and not overlooking items that look safe on the surface.

Only with high resolutions or precision the resistive voltage drop can be significant. Since large signal currents flow in this case, the error gained can be compensated.

To avoid any voltage drops, the use of separate sense (S) and force (F) connections is usually done. However, this solution is only applicable to systems with negative feedback. You cannot utilize this arrangement to systems with equal accuracy because feedback takes only from one point. Additional methods should be done.

Ground Issue

One of the major concerns during the process of grounding is the return current. The most common approach here is the assumption that there will be no ground voltage using the concept of infinite ground conductivity. However, it cannot be applied circuits with high precision. It can only cause major disasters. The next approach to this grounding issue is the impedance analysis and noise voltages minimilization. This one is more realistic than the first approach. On this concept, it is assumed that voltage drop can be caused by the current of signal return which flows in complicated impedances.

PCBs with two sides and multiple layers

There should be a minimum of one completed layer intended for a ground plane. Usually, if you have a printed circuit board with double sides, the one side is for the interconnections while the other side is for ground planes. However, it does not happen in reality because some portions of ground planes should be eliminated for crossovers of power and signal. The rule here is at least 75% of the area must be retained. There should be no any secluded ground islands. Moreover, there should be no any skinny connections because these can degrade the ground plane’s performance. It is recommended to utilize manual intervention techniques on printed circuit board with mix signals to avoid any disaster.

Lanyards for Campus Unity, Anyone?

Once upon a time, lanyards were created and introduced to schools to serve a very practical purpose: to hold the IDs of students and staff. Nowadays, lanyards bear the schools’ logo and name, with the tagline sometimes, and have become a part of the school uniform. In short, ID lanyards are worn to promote the age-old virtues of unity and school loyalty.

While students may have varying views about school administrators mandating that they wear lanyards.

Here are some reasons why they should really be sporting them :

1. The student body looks more professional with school-issued ID lanyards. Nothing could be more pleasant to see than all the students wearing the same cord, with the same color and length. Imagine students who wear their IDs in the most inappropriate places like those clipped at the hem of their shirts or at the garter bands of their pants.

2. ID lanyards promote school spirit.Some schools order customized ID laces and they ask for the inclusion of the school’s logo, name, and tagline, if there’s any. Some lanyards are printed with the school’s motto or foundation anniversary theme. These design elements encourage students and the staff to be proud of their school.

Lanyards3. They lessen the cost of lanyards.Since these lanyards are bought in bulk, the manufacturer would sell them at a lower price. Besides, uniform designs are easier to make, so the school would be paying less for manpower.

4. ID lanyards facilitate identification and could be a potential life-saver.While it is hoped that this does not exactly happen to students, but in cases of crime or any inconvenience, it would be easy for the police to identify a person especially if he is wearing a lanyard. CCTV cameras do not capture the face of a person that much, but with lanyards authorities could easily determine whether a person is a student and which school he comes from. While it’s a part of a lanyard’s main functions, security personnel could also make use of lanyards for identification purposes.

5. These ID holders make life simple.You do not have to fuss over your ID as you simply flash or let it hang on your neck. It saves you from the trouble of rummaging in your bag.

6. Lanyards are also a way of promoting responsibility among students. Seriously, how hard is it to wear lanyards? Sure it may be a little tricky to pin your ID, but wearing it with a lanyard makes things easier. Meaning, students will have no excuse not to wear their IDs.

7. Wearing ID lanyards would make you feel that you are really part of the school. Call it campus unity if you will, but you would really feel safer and more grounded if you’re wearing proper identification.

If lanyards are so important, why do some students dislike wearing them? Some say that lanyards are only for freshmen, for the uninitiated. Others think lanyards are too self-limiting because somehow students are not allowed to wear just anything, more so if they refuse to wear their IDs. Add to that the “wear-it-or-else” rule in schools that make the atmosphere tense.

So what could probably be the answer to this? How can schools promote campus unity without being too rigid about wearing lanyards? The best option is to include the student body in the customization of ID laces. A competition could be held so that all students would be called to submit their ideas. Students will love this and they will be extra proud that their works are worn by their fellow students.

Simply put, they will enjoy designing their lanyards, thus encouraging campus unity in the process.

Golf Equipment – From Clubs to Bags

For a lot of people who play it, golf is a lot more than just a sport. It is a way of life. Golf is not just something that people play and then forget about the next day. There are some who have incorporated the sport into everything that they do. When it is time to play the game; there is nothing that can get players out of focus.

Playing golf is a lot about the skill of the players although very crucial in the game, their skills can still only get them so far. Just like any sport, golf players also rely on the equipment that they use to enhance their own abilities. This is the reason why people take their golf equipment so seriously. There are players who will go the distance just to be able to get the perfect equipment for them.

People who are just new to the sport might feel a bit worried about all the equipment that golf requires. The sheer variety of equipment can be a bit daunting for amateurs. Before making a purchase, there are a few things that person needs to know. He needs to familiarize himself with all the things that are required in the sport.

One of the key golf equipments that a player need is the golf club

golf equipmntThis is something that is essential in the game. Without it, people would not be able to enjoy the sport. There are tons of clubs that a player can choose from. Usually, the basic set consists of three to four golf clubs. However, a golfer may choose to add more, based on what he needs for the game. Each type of club is meant to be used for a different situation. Those who play golf do not always know what obstacles the course can present to them. It is important for players to have several kinds of clubs to be prepared for any situation. This assures them that they are able to play their best no matter what.

Another equipment that is probably just as important as the golf club is the golf ball

This ball is designed to go extremely far because of the dimples on its surface. The dimples are placed around the ball to make it more aerodynamic. It is important for a golfer to have several golf balls in case he loses one of it.

One of the most iconic pieces of golf equipment is the golf cart

This small, but functional cart has become so popular that people do not just use it for golf anymore. They use it to travel short distances. Golf courses are huge; they are so big that is would be such a hassle to travel throughout the entire thing carrying all types of equipment. The golf cart is meant to make traveling around the golf course so much easier. It can also store a golf bag, which will have everything that a golfer will need throughout the entire game.

The golf bag is equipment that is a must-have for any golfer

As mentioned, this piece of golf equipment is meant to store everything that a golfer needs. It has a place for everything, including both the golf clubs and the golf balls.

These are some of the things that a golfer will need. As mentioned, for a lot of people, golf is not just a sport; it is a way of life. Even things like clothing have to be closely monitored when playing golf. To put it simply, all these items are meant to improve the game of each player.

The Staples of Web Design You Should Utilize When Publishing Websites

No matter what type of website you want to put up online, you will want to look into several elements that will help you build market share. If you just go with any old design influence, you are going to end up seeing a huge drop in your traffic, and perhaps get a backlash overall. It’s important that you do not allow yourself to go with antiquated elements of design flow, and then try to market your site like it is 1999. There are a lot of people that get the wrong message when they are updating their websites, and it’s evident that they are not sure what they are doing when you visit their pages. Whether you want to work with affiliate marketing, or you just want to set up a blog, you’re going to find yourself amidst a lot of problems when you end up putting up the wrong elements of design. The following are staples that you should work with if you’re going to hire a programmer or going to update your own site alone. Even though there is an evolution going on in regards to marketing collateral and design, you will find that the following will still work and are staples web design as a whole.

Easy To Use Navigation

No matter how many times things change in the design world, you’re going to see that this is a very true element. The end user that shows up on your site has to know what to do and they shouldn’t have to think about how to work your site. If they have to do too much thinking, then you are going to end up losing out overall. Easy to use navigation is the key to setting up a page that is going to stand the test of time. The only sites that don’t need a huge navigation element is blogs.

web designHowever, the blogs that you set up have to point back towards other places on your site, including links, and variations that are going to help you get a good deal of traffic. If you do not focus on using this in the right arena, you are not going to get moving forward within the right parameters. Without navigation at the helm of your page, you’re going to end up losing out.

Simple Color Schemes

There’s no reason why you should have too many colors. Some people assume that you need to build a lot of different pages with colors that are all over the place. Color schemes that are associated with design should be simple, and easy to navigate. If someone is surfing your page at 3 in the morning, they shouldn’t be blinded by what you’re doing. The simple colors are going to allow you to get more people seeing your site and not having to drop out because it’s too bright, or too confusing. With that in mind, you should also look at the color of your text. You should have your site easily readable, otherwise you’re going to find that people will not see what you’re putting up or want to read anything.

Diversity In Your Publishing

The best sites online, the ones that win a lot of awards for web design don’t just have one type of content element updated on their page. They have several different types, and they put it all up front for the end user to choose. Most people don’t realize that people land on pages that are published through a variety of links. They are not landing on pages that are on the index page. You will find that if your index page is not done well, you’re not going to get moving forward with relative ease. You have to diversify your reach and make sure your publishing is doing well overall. Diversify your publishing elements unless you’re working on a “essay” website, in which case you will want to post thousands of words overall. It’s imperative that you are working on diversity or you will get left behind. This is as much an internet marketing element as a web design element.

Focus on The Code

web designsAs far as publishing is concerned, make sure that you are hiring a good firm to work on your code. If you’re going to do it all yourself, then make sure that your code structure is clean, focused, and noted. Do not just publish code that is messy or that is “functional”. Functional code will help you set up a site but it could also come with a variety of issues. You don’t want to look at code that is messy and search engines aren’t going to target your page well if you end up having messy elements on the back end.

At the end of the day, you will want to have the above staples of web design in place, and focus on building pages that are going to get indexed fast within search engines. Otherwise, you’re not going to get moving very far in regards to the marketing world. It’s imperative that you look into this and build the right pieces, or you could get left behind, and that’s a bad thing. Getting left behind today, means no traffic or conversions at all.

Smart Investing in Residential Real Estate

Whether you’re in the market to find a residential real estate for occupancy or leasing, choosing the right location, property type, and home features can help make your purchase a profitable investment.

A desirable real estate market is an area with high appreciation potential. Communities with stable or steadily rising home prices are safe bets for your money. Brisk local business and continuous development in and around the community means there are jobs to go around, encouraging residents to stay within the area and enticing new residents to settle down. These factors help drive demand and home prices up.

Besides looking at home price indices and unemployment data, home buyers are typically on the lookout for properties located in master planned communities that offer clubhouses, pools, nature areas, playgrounds, parks, hiking trails, and other amenities. Malls, retails shops, and high quality schools are definite add-ons, and so are historical sites, tourism spots, and fine beaches.

Some residential property types do well in certain places or areas, but may not be as popular in others. An investor should be shrewd enough to understand market needs and build a real estate investment portfolio based on market trends and requirements.

Below are the types of residential properties:

• Single-family Residences:

The most common property type, single-family residences are stand-alone structures that support only one dwelling or family. These are commonly the cheapest properties to purchase.

• Townhouses:

A type of single-family dwelling, townhouses, are typically two-storey houses that share side walls with an identical house and are usually terraced.

• Vacation Homes:

Otherwise known as second homes, holiday cottages, or holiday homes, vacation home are commonly located near beaches, ski resorts, or leisure areas and function as seasonal accommodation for the owner or rented out to other vacationers through an agency.

• Multi-unit properties:

Multi-unit properties are residential properties with two or more housing units contained in one building. They may also refer to a residential complex with several buildings.

• Modular Homes:

Modular homes are built off-site, usually in a controlled factory environment where they are prepared in sections. They are engineered and assembled based on state requirements and building regulations of the prospective location. After completion, they are delivered to the site and installed on permanent foundations by a professional installer.

• Manufactured Homes:

Otherwise known as tiny homes, trailer homes, or mobile homes, manufactured homes are pre-fabricated structures constructed on a permanently attached steel chassis which allow them to be moved.

• Condominium:

A condominium refers to the individual ownership of a specified part of a building and the right to use common areas and amenities which may include the lobby, pool, spa, or sports center. The rights are managed by the association of owners.

• Condotel:

A condotel is a building which is legally classified as a condominium but operates as a hotel. It can serve as a permanent or long-term residence, or may offer short-term occupancy. Condotels usually maintain a front desk or concierge.

• Investment Properties:

An investment property is a property which is not occupied by an owner. It is owned for the purpose of realizing profit either through rental or appreciation. Investment properties include single-family residences and multi-unit residential properties.

real estateFinancing options and interest rates vary with each type of residential estate. Single-family residences are the easiest to finance and carry lower interest rates while financing for condos usually have higher interest rate. Both modular homes and manufactured homes may be financed through personal loans.

Besides paying attention to location, home buyers typically look for features which make a property special, energy-efficient, and practical – things that add overall value to the investment.

Here are some of the home features that not only make life more comfortable but increase the property’s resale value as well:

1.Outdoor living spaces:

Home buyers hanker for outdoor living spaces, which includes having an outdoor fireplace.

2.Double car garage with storage area:

A double or triple-car garage gives ample storage space besides accommodating parking needs of couples or families.

3.Closets and storage spaces:

Lots of closets and storage spaces are great for keeping things organized. If your potential home has inadequate storage space, it should at least have some functional area that can be converted for storage purposes.

4.Natural Lighting:

Natural lighting that flows into the house is relaxing and stimulating, not to mention energy-saving.

5.Unobstructed view:

An unobstructed view of parks, bridge, skyline, river, and mountains can be uplifting and definitely does a lot to increase property value.

6.High ceiling:

High ceilings reaching to about 14 feet is a luxury that many home buyers wish they have if they can afford it.

7.Heavily insulated Windows:

Double-paned, heavily insulated windows protect against outside noise and bad weather conditions. They are also necessary for preventing heat and cooling loss.

8.Architectural design:

A house with sturdy, practical, and unique architectural design is more likely to last for decades and fetch high resale value. Intricate details, solid foundation, and high quality materials combined with great artistic design are qualities that will never go out of style.

9.Practical Layout:

Practical house layout allows residents to move with ease from indoor living areas to outdoor spaces and back.

10.Smooth interior layout:

The floor plan or the interior layout should allow for easy and natural flow from one indoor space to the next.

Whatever your investing needs are, do keep in mind that we have the widest range of Long Island properties and services to help you realize your dreams.

How to be a successful motivational speaker

Being a motivational speaker is not easy. You have to be a good public speaker, and public speaking is not the forte of very many people. You will constantly be asked to be the keynote speaker at seminars, conventions, and other events, which can contain up to thousands of attendants. The basic skeleton of your presentation will continually have to be customized in order to meet the needs of the specific audience. On top of all that, you have to have an edge over other speakers.

Motivational SpeakerWhat makes your story any different from the rest? What ideas do you have on motivation, performance and behavior that will have corporations pining for you to be a keynote speaker at their next conference? In order to be successful as a motivator, visit motivational-speaker-success.com also here are a few steps that aspiring speakers should follow.

1. Select the topic that you want to discuss with the public

Typically, a motivational speaker is hired by a company so that he can talk about strategies for company growth, but success can be seen in a variety of aspects in life, like in relationships, finances, and personal development. Choose the topic you feel that you have the most insight in.

2. Make sure your key points and overall message is relevant to present circumstances

You have to make sure you are up to date with whatever trends that are happening in your new area of expertise. Your understanding of the subject has to be applicable to the present. This will require additional research as well as staying up-to-date with your field.

3. Identify your audience

Who is your speech for? You will come across different kinds of audiences, so learn how to be flexible with your methods of communication and delivery of your message.

4. Improve your public speaking skills

No matter how good you were on your college debate team or the number of speeches you have delivered throughout your career, it’s recommended to take public speaking classes. Just as it was mentioned before, every audience is different and you will have to learn how to adjust without panicking. You will have to speak in front of large groups and sometimes you will be expected to speak in a more intimate setting. Another way to improve your skills is by recording yourself so you can have a look firsthand what exactly it is you need to change. Writing is also a helpful activity, and a written guide or pamphlet serves a guide for audience members during your presentation. Share your written works on a blog or website.

5. Think about your presentation

Having a presentation in the background can really boost your speech, but remember to choose tools and devices that you are familiar with to avoid any technical errors, especially while delivering your speech as a keynote speaker.

6. Make yourself known. Promote yourself

As you are starting off, you will have to find an appropriate venue for your presentations. When you’re invited as a keynote speaker at an event, this trouble is off your hands, but for now, find a conference room or an auditorium, depending on the size of your audience. Then market yourself with posters, ads, brochures, cheap tickets, or even free tickets as a starting point. You should also sign up on bureaus for speakers and potentially find conventions and seminars that you can offer your presentations to.

7. Lastly, ask for feedback from your audience

Take in the feedback from your audience, adjust your presentations if you have to, and post positive testimonials on your brochures as well as your blog or website.

Keep following these steps throughout your career and you should be golden

Custom Military Coins and their Value to the Men and Women of the Armed Forces

Custom military coins are coins or medallions that display the symbol and other identifying marks of a military branch or unit. They are specially minted for distribution among the select few who have been appointed to serve together for a common goal.

The traditional shape of the military coin is round. One of the oldest military challenge coins on record was the coin batch ordered for engraving by Col. William “Buffalo Bill” Quinn from the 17th Infantry Regiment. The military coins were minted for distribution to his men during the Korean War. A hole was drilled on each coin for ease in wearing the custom coin around their neck.

custommilitarycoinsMore modern coins showcase unconventional shapes such as shields, crosses, stars, wings, skulls,cross bones, and crests. When imagination is the only limit in crafting the military coin to represent a unit or an organization, you can be sure to find creativity at its finest.

The Air Force, Army, Marine, Navy, Coast Guard and their units have their own emblems that are commonly reflected on custom military coins specially minted for the men and women who make up each military branch. Military coins are a great way to commemorate the time and hard work spent with a unit or organization. The unit members who collect and keep them as mementos will always treasure the distinctive camaraderie that is only seen within the military circle.

That extraordinary bond is evident in coin challenge games or coin checks where all unit members are compelled to bring and present their military challenge coins wherever and whenever demanded by a comrade or a unit officer. There is usually no bar to the time and place of challenge, and it may be posed virtually anywhere. The familiar sound of a coin can send waves of panic to the unprepared. There is no escape from the consequence of forgetting or neglecting to carry a military challenge coin.

While military coins are more commonly used in challenge games, custom military coins are highly suitable for celebrating rites of passage that not everyone gets the opportunity to achieve. Military coins are more valued than paper commendations because they are durable and not anyone can print or make them. Their recipient knows that each custom military coin went through the long process of designing, crafting, proofing, and finalizing before they can be issued to deserving members. Unit commanders and officers know the latent value of presenting those special coins only to excellent achievers.

A hard-earned, custommilitary coin is most coveted and treasured. For this reason, many officers and unit leaders limit the distribution of specially crafted coins to a select few or elite members who must meet preset criteria for receiving the coins. Military coins may be presented to celebrate an anniversary, a task excellently accomplished, or for qualifying as a member of a certain group.

A task force consists of a number of military, government or law enforcement agencies that work together to meet a common goal. These highly trained individuals fight organized crime, illegal drugs, and gang violence. An excellent means of commemorating their efforts is through customized coins.

Custom military coins are perfect for promoting cohesion and team spirit within task forces created to handle sensitive missions. They are great for building the morale of the members of the force who know that they are being recognized and honored for the special assignment. Seeing their name, badge number, and rank engraved on the custom coin creates a great sense of pride and loyalty.

With one excellent act or deed, a military challenge coin may just be a handshake away.

How to Maintain Your Misting Fan

When summer is fast approaching, we often overlook the need to prepare our trusty misting fans. Yes, our misters must be ready even before we start thinking heading outdoors for summertime fun.There is nothing more annoying than organizing a barbecue party at your backyard and having a mister that will suddenly stops working mid-way. Here are some ways to prepare and maintain your misting fan to ensure its optimal working condition.

MistingFanFirst, you have to check the fan’s oil level at the pump. Add some oil if needed. You may also consider removing the old oil and change it with fresh oil. This can keep the fan running smoothly for longer periods of time. The majority of the commercially available misting pumps require changing after about 500 hours of usage. Nonetheless, you may always refer to the user’s manual to determine the exact changing interval and oil type.

Second, you also need to check the water filters. Make sure that these are clean. If not, clean the filters thoroughly. Check if there are any missing or broken pieces and then, repair or replace the parts accordingly. Also, you need to secure any loose screws. Check other fittings and connect them properly if needs be.

Third, check the nozzles of the misting fan. If you have to prepare the entire line system for flushing, remove the nozzles connecting to the misting system. However, if you don’t know how to do this, ask the help of an expert. Do not attempt to remove them by yourself otherwise this will lead to an irreparable damage. Turn the pump on to start flushing out the remaining water. Leave it for about 30 seconds to 1 minute. Turn it off and connect the lines and nozzles.

Fourth, after connecting the lines turn on the pump again to start flushing the entire misting system. Let the remaining water in the system flows out of the nozzles. When you notice that water is only flushing out from specific nozzles, check the nozzles again. There could be some blockage. Let all the nozzles flush for 30 seconds or more if needed. Turn the pump off. Connect the mist nozzles on the nozzle fittings where water is running smoothly. Repeat the entire process for proper flushing.

Fifth, if there are blockages on the nozzles, clean them so that they will work properly. However, you might need to replace them if most of the nozzles are working improperly. There are many replacement misting fan parts offline and online. Go to the nearest hardware if you need the replacement parts immediately.

Sixth, let the pump run and then check if there are leaks. Once you’ve discovered a leak, turn the pump off and reset or tighten the connection. Turn the pump on once more and check if water is still leaking or not. If it is, replace the part.

Seventh, you need to hose off the misting fan. Clean misting fans especially clean fan blades work more optimally than dirty blades. You simply need to wipe the mist fan with dry towel if it is not outdoor-rated (misting fans without enclosed motors). The fan motors might get wet and a short circuit might start. Before operating the fan again, make sure that all the parts have dried up completely.

All of us have the tendency to ‘winterize’ our misting fans. The changing season is a good reminder that we have to make our misters ready for summer. This is particularly true if you want a trouble-free cooling during hot summer days. Anyhow, it is our responsibility to maintain our appliances, and our misters are not an exemption.
