How PCB Design Affects the Performance of a Device

To have quality machines and devices means they must be made with quality components as well. Thus, devices must be designed for reliability. Otherwise, they will be rendered useless or obsolete in a short span of time. A device can be reliable for two things: one, it lasts; and two, it can carry out what it was originally meant to do. Suppose a mobile phone has a lot of glitches and cannot be used for sending messages, then what use does it have for people?

How a device performs also has something to do with how it was manufactured and design. Printed-circuit board (PCB) fabrication figures a lot in this aspect. When a design is right, it will offer the following:

Thermal Reliability

PCBCan the PCB conduct away heat? If it does not, it might result to problems and failure. PCB fabrication and design should prioritize thermal reliability so that the device does not heat up and conk out. Hence, the PCB board must be able to remove heat through convection and keep the components of the device cool and dust-free.

Electrical Reliability

The PCB layout software must determine the noise in narrow traces, insufficient current-return paths, and cutouts in ground planes. When this noise has been blocked properly, interference and other technical disruptions will be prevented. If you are designing your own PCB, make sure that the signal delivery has its own return-path, and that this return-path must be parallel with the signal line. Any break in ground planes or power will cause disruptions, and possibly, major problems.

Thermomechanical Reliability

An inflexible solder will crack and fail. This happens when the size of the PCB solder is not aligned with the leads of the package. Moreover, there must be a pattern created beforehand to ensure that the solder deposited to the PCB is of the right quantity or size. Keep in mind that thicker PCB boards are less flexible and may cause damage to solder joints. In contrast, a thinner PCB board bends more easily and lessens the stress on the solder joint.

Mechanical Reliability

Similar to thermomechanical reliability, mechanical ability accounts for the solder joint attached to the PCB board. When a solder joint becomes too stressed by bending, it can lead to cracks and leakage. Another cause of solder joint stress is shock damage, wherein vibrations or slight tremors pass through the PCB. One way to reduce solder joint stress is to use frames or plates that even out the distribution of shock waves.

At the same time, PCB mount connectors may improve the reliability of a device. These d-subminiature and standard-density mount connectors have been found to improve reliability and at such low prices. If you are thinking of creating your own PCB design, then you might want to get samples of such connectors to avoid any glitches in the device.

Clearly, PCB fabrication and design has a huge impact on device performance. Thus, it is crucial for engineers and other PCB developers or creators to use standard materials. When done properly, devices would also work in their best capacity. Any problem with a device is attributed to its internal machinations, and must be addressed preemptively.

Fortunately, there are tools that facilitate PCB fabrication and design. Multisim 7 simulation and Multicap 7 schematic capture tools improve and accelerate PCB board design. With these two, schematic entry tasks are reduced, information can be stored in a special database, and analysis is faster and better. Parts are also easily found and placed. Should developers and engineers lack these tools, they can always rely on other strategies to ensure that their PCBs will deliver the task it was intended to do.

Uses of Custom Coins

If you ask a random person about what coins are, he would most likely tell you that coins are money. After all, growing up, that’s what everyone has been taught. When you were a kid, your parents probably taught you about coins and about spending by letting you use coins to buy yourself some candy. As you grew older, they gave you more coins, until you finally graduated to paper money. When you eventually reach adulthood, coins became those things that get buried at the bottom of your bag, making it heavier.

These are the things that you want to dispose of, because they’re too heavy, or too much of a hassle to carry in your wallet.

This being said, did you know that there are other kinds of coins out there? In fact, there are kinds of custom coins that have no monetary value, but can have some sort of sentimental value to the owner.

For one, custom coins are most often used in the military as challenge coins. These may either be given as an award to the soldiers, just like how medals are handed out, or these may be given because the recipient is a member of a unit that has one. The history of carrying around military challenge coins started out in World War I, when it helped one soldier escape execution by the French. Since then, it has been a tradition to always have your military challenge coin with you at all times.

Challenge CoinCustom coins may also be used as a marketing ploy by big corporations. Not a lot of people know that there are groups all over the world that have coin collecting as a hobby. These groups immediately know if some entity is going to release limited edition coins, and they are usually the first ones in line for these custom coins. Corporations know this, and they have used coins as a means by which they can draw attention to their products. They release limited customized coins with their design. This eventually allows them to get attention from people all over the world.

Moreover, nowadays, custom coins are also being used as business cards. These people have coins manufactured that have the logo of their company, and their name and contact details engraved. If you think about it, this actually makes sense because it will definitely leave an impact on the recipient, leading them to become more interested. Business cards made out of paper or cardboard can easily be destroyed and torn apart, but these kinds of business cards will survive for a very, very long time.

You’d be surprised that these coins also have a use for weddings. They have various uses during weddings, actually. For one, in case you have a Catholic wedding, customized coins can be used during that part wherein the bride and groom hold the arrhae together to symbolize prosperity. Ordinarily, normal coins would be used for this part, but customized coins may also be used to put in a unique touch to the wedding.

Furthermore, these coins can be a save-the-date marker, or even the souvenir for the wedding celebration itself. If used as a save-the-date marker, a magnet can be glued to the back of the coin, and it can be a magnet that’s ideal to be put on the fridge. That way, it can constantly remind the recipient of the date for your wedding.

Truly, there are numerous uses for these coins. The next time you see a customized coin, take the time to read or actually see what is on it. You’d be surprised at the kind of stories you will discover.

We don’t charge for design, art or revisions, so you can experiment with the design of your custom coins until they’re exactly the way you want them.

6 Lies Bad Realtors Tell Their Clients

We are not saying that realtors are trained liars. What we know is that they really exist like in every industry. In response as a property finder, we provide only the most reliable realtors you can find in the state.

Just to give you an idea of how the industry really looks like from the inside, here are six lies that some realtors tell their clients.

1. Your house is more valuable that you think it is.

Many sellers overprice their properties for personal reasons. Unfortunately, many realtors also play dirty with it, so they ride along with their miscalculations just to make sure that they sign up.

When a seller asks about the possible selling price of his real estate, he wants to hear good news which you can read as high price. The happier he gets the better chance the realtor gets to sign him up and eventually earn a commission.

As a seller, you should have an idea of the on-going fair market value of properties in your area. You know when a realtor seems to be playing based on your own estimates. Be objective for you to see clearly the real value of your property.

2. The real estate you want is a guaranteed moneymaker.

Some realtors tell their clients that a house or lot is bound to appreciate in the next five years or so. Some say that a particular property is perfect for leasing. Some even go the extent of advising their clients to establish a business in the address, or take down the current structure to build something more lucrative.

RelatorsWhile some of these unsolicited advices sometimes have merits, most of time, these are nothing but personal opinions that appear credible because of their positions. Realtors normally don’t have a background in economics, finance, or engineering. Otherwise, the real estate industry shouldn’t have been a big problem when the recession hit.

Property management is also another field within the same industry but is handled by another set of licensed professionals. While a realtor’s relationship with a buyer ends at the signing, a property manager’s relationship with a leaser and tenant doesn’t end until the contract expires. Nevertheless, some realtors are also licensed property managers.

3. The house is in perfect condition.

A realtor wouldn’t know that for sure unless he has done all testing procedures to clear the house from any anomalies. The problem is that most sellers don’t want to put their house under various testing procedures because they can sell it without any of those anyway.

It’s simpler to inspect for wood problems, but pest control companies have more technical methods than mere visual inspections. A working power line and outlets usually say it all for a realtor, but a technician will inspect not just the connection but the quality of wires as well, something that takes a while and a couple grand more. Even mould and mildew problems usually take a forensic expert to be ascertained.

When a realtor says that the house is in perfect condition, he is probably saying that in good faith because he is confident in what he is selling. However, don’t take the word “perfect” in its literal sense because it rarely is.

4. The real estate is as it is as described.

Descriptions are commonly different from the actual property by a slight margin of error. Why? It’s because copywriters are better with words than property owners are with housekeeping and maintenance. Good marketers will always find good selling points in a bad property, and these include good angles for a photograph or good landmark near the address.

This practice is so common, but we dare to rectify the system and provide properties as what they really are and not what we want them to be. Realtors should also be like that. They should only give the facts, liaise for the negotiation, and assist where both parties need him.

5. There are a lot of properties to choose from.

This is a lie depending on how you understand it. There are more than 12,000 properties in New York City that are currently on the market, but would you believe that the number of real estate agents are more than double of that figure—more than 27,000?

The number of properties says that you have more options than you can handle. However, the number of agents says that not everyone makes a deal, and less than half of those who have closed deals also have priority clients that you have to compete with. Most of the time, the business works in a first come, first serve basis.

It should also be considered that when narrowed down, the properties that fit your requirements will probably be less than what you need to find the dream house you need. In fact, there are realtors who wait for years to give their VIP clients the perfect home.

6. The set commission of a realtor is 6%.

A commission rate of 6% is considered as the industry standard. However, this is not mandated by law like tax, and even realtors who belong to firms usually don’t have contracts with definite commission rate. Commissions are flexible, so the last resort when a buyer wants to haggle with a property so bad is to take a cut from the realtor’s commission. Three to five percent commission is still better than zero
