How to Solder a Printed Circuit Board Properly

Soldering is actually a skill. You cannot solder a perfect fix in one go. You cannot have a clean and working printed circuit board if you do not handle your soldering tasks properly. You can waste hours of PCB preparation if your soldering skills are poor. You need to practice constantly and effectively learn from your past mistakes. This article will teach you on how to solder properly. Below are some of the guidelines you can use:

pcbnet1. Always use a soldering iron that is in good condition. The soldering iron is the heat source that is used to melt the solder. Always inspect the tip. The tip must be pointed and not dull. Many soldering irons, however, are bought flat and fat, and not very pointed. If that is the case, then being clean is enough. You can use a sand paper to clean the tip of the iron. It must be done while it is unplugged or if it had enough time to cool down after a soldering task.

2. If your goal is to solder for a printed circuit board, then you must always choose a soldering iron with a lower wattage rating. It can range from 15 to 30W. Irons within that range are enough for most boards. Anything with higher wattage may damage your PCB or your components.

3. Always allow the iron enough time to heat up before doing any soldering tasks. It will save you the frustration of wondering why the lead is not melting. If the iron is now heated, then you should select a hole of a printed circuit board with component pins to solder.

4. Apply heat first to the ring with the drilled hole. You must use the side of the tip of the iron. Do not use the actual pointed tip because it will only damage the board, and your own iron, as well. After a few seconds, feed the soldering lead in between the ring and the tip of the iron. You will see that the solder should flow through and around the component, and the hole. You must adjust your grip if the solder is only positioned in one location.

5. A good solder must have a volcano-shaped mound, which is colored silver-white. If your solder forms a ball, then you can use a de-soldering tool or solder vacuum, and repeat this step until desired shape achieved.

6. Repeat until all of the holes on the printed circuit board are filled up with these volcano-shaped mounds. You can also use a soldering flux or paste to achieve better adhesion. The soldering flux can also be used to clean the tip of the iron after every solder. You can also dip the tip of the iron to a wet sponge. This can prevent the iron from overheating, and at the same, clean the tip from left-over solder. Maintaining the heat of the iron can prevent damage of the PCB, and can prolong the life of the iron.

7. Use a multitester with a continuity function to check if your circuit will not short. Always remember that a short circuit is hazardous and may cause fire.

8. Optional: Use a flux remover or electronic contact cleaner to clean the board. The board can be sticky and messy after you finish your soldering task. The rosin flux from the soldering lead and paste is the cause of the mess. You can also use isopropyl alcohol.

You have learned valuable tips on how to solder a printed circuit board properly. With enough practice, your PCB may appear to be professionally made. Just practice, and you can gain a skill that you can use in creating valuable electronic circuits.

Various Types of Custom Challenge Coins

Do you know what a challenge coin is? It is a simple coin which is mainly used by military units to show their loyalty and commitment to their unit. Each coin has its own distinct design which best represents a military unit’s vision, mission and motto. Mostly, the unit commanders and combat officers are the one entitled to give such coin as a mode of recognition or appreciation to the soldier who shows an excellent performance during a particular battle.

At first, custom challenge coins are only restricted to military servicemen. However, another tradition was started by the United States Air Force and it was then called the “Bull Dog Challenge”. This tradition is about giving custom challenge coins among enlisted gunners after the graduation rites. As of that time, challenge coins are limited for B-52 bomber crewmembers, particularly those who occupied the big bomber aircraft’s tail gunner position. Such coins signify the bravery, courage and strength of all soldiers.

Nowadays, you can see several types of custom challenge coins offered by different manufacturers. Due to its popularity, challenge coins are now utilized even outside the borders of military groups. Such coins are now bought and given as a present or collection. In this article, you will learn about the different types of such coins. These types are also used even outside the parameters of the military.

Challenge CoinsThe company known as the Harley Owners Group, abbreviated as H.O.G., has been creating and selling exclusive coins with distinct styles and designs. Their coins are only offered among motorcycle owners. Like how military groups value their bond and friendship, Harley Davidson heads and customers build a strong bond by owning a special coin. The coin also represents how proud the owners are to have a unique challenge coin. The Harley Davidson heads instruct their customers to always bring their challenge coin wherever they go or to display it on their own motorcycles. That coin carries the company’s logo and the phrase “The Official Riding Club of Harley-Davidson”. The main material for creating the coin is solid brass alloy and the finish looks like an antique. The Harley Davidson coin’s price is 12 USD per coin.

Another challenge coin was made by the Utah Symphony and Opera. The group usually gives custom challenge coins to its faculty and musicians. This practice was done since early 2000’s. The reason of the group is not clearly stated but many people believe that it was given to show the leader’s gratitude among his members for joining the opera.

Many people would like to give unique gifts. Due to this reason, challenge coins may be given to your special someone, family and friends. Some would use it as badge of appreciation. For instance, renowned film director Jon Favreau distributed Iron Man-inspired coins among personnel of the United States Air Force. His reason why he gave such coins is that he is thankful for their participation in the top grosser film, Iron Man 2.

Another group that distributes challenge coins is the National Association of Buffalo Soldiers and Troopers Motorcycle Club. The coin that was distributed has a diameter of 1.75 inches. The material used is solid brass and the coin has an antique-like finish. Like any other coin, the logo of the group is present in front of the coin. At the back of the coin, you can see their slogan: “We can, We Will”. Such coin is only given to a person who has been exhibiting an excellent performance. This coin is usually given by the head officer. Not all people can own this coin and thus, it is a great honor to own it. Whatever challenge coin it is, the main purpose why such coin is given to a particular member is to show that the leader appreciates his effort and excellence.
