Hand soldering is an essential part of every manufacturing company for reworks and maintenance even though they are using automated soldering in the production. The automation help keeps the company achieves a high quality soldering because of the high demand for quality products. To ensure efficiency, these products are carefully inspected and when there are some faults, hand soldering is needed. Electronic boards nowadays consist of densely packed resistors, ICs, and other electronic components which make it more complex. In this manner, proper training is needed for those who do the hand soldering to prevent expensive damage.
Every technician should have the right knowledge when it comes to printed circuit boards so that it will not be difficult for them to locate the parts that are needed to be reworked or maintained. These printed boards are usually made of materials that have a good dimensional and thermal stability. The components are usually designed in the manner that it will be easily soldered directly to the board’s surface. There are also board types that are sandwich with other boards with plated through-holes which provides connectivity between the layers.
There are three classifications of products which are namely: Class 1 which is for general products, Class 2 which is for those products that has better performance and last long, and Class 3 which is for those who are use for harsh environments. Each components of the class are soldered following the same standard, meaning that it should have uniform in appearance. When it comes to soldering, inspection, and manufacturing processes, standard plays a vital role in it. Each electronic manufacturing company must follow these standards to ensure that they can produce quality products. The IPC standard is the most common that are use by many companies worldwide.
There are two types of solder namely, leaded and lead-free alloys. The lead and tin alloy are the most common but due to their nature of being hazardous to the environment and health they are slowly being phased out and being replace by lead-free alloys. When it comes to lead-free alloys, it is still far from perfect because unlike lead alloys it needs a higher temperature to melt. When using this, the technician should be careful most especially when soldering tiny pads. Lead-free alloy also are expensive unlike tin and lead which are lower in cost.
Training is really important to those who are aspiring to become a good technician especially when it comes to soldering techniques. There are a lot of training centers that offers such courses. You will really learn a lot from going on a soldering training. And you will get a certification once you complete the course.
Lowell Gladly an online writer recommends Blackfox Premier Training and Certification if you want to learn more about soldering and if you like to become an IPC instructor.
