Double-sided circuit board is the most common type of circuit board in the printed PCB industry. Double-sided circuit boards are used in a wide range of fields, ranging from household appliances to medical industries. So for professional soldering, what are the most common methods of soldering double-sided circuit boards?

Modern printed circuit boards (PCB) are the lifeblood of today's technology. It's nearly impossible to find electronics without some form of PCB. While a professional PCB manufacturer is required to produce high quality printed circuit boards, you can create your own homemade PCB

In the work of debugging and repairing electronic equipment, it is often necessary to replace some components. The premise of replacing components is of course to desolder the original components. If the method of desoldering is not proper, the printed circuit board will be damaged, and even if the components do not fail, they cannot be reused. Desoldering is more difficult than soldering and requires proper methods and tools

This is a detail that engineers rarely think about. Today, AiXun will take a look at the general opinion with you. Let's understand this green board first

The component is fixed on the PCB by soldering through the lead hole on the PCB, then the lead hole and the surrounding copper foil are called pads. It is essential to have a rich knowledge reserve of pads for an excellent PCB engineer. Many people can draw pads according to the component manual, but it is not easy to draw good pads. AiXun shares some tips below, hoping to help you learn more pad basic knowledge.

Pad shedding, also call pad peeling off, refers to the phenomenon that the pad is separated from the PCB. This is a common adverse phenomenon in the PCBA processing , especially in the subsequent maintenance process. The pad refers to the conductive pattern that provides electrical connection on the PCB. As a necessary medium for the soldering and assembly of electronic components and PCB circuit boards, the importance of the pad is self-evident. Once the pad peels off, it will lead to PCBA products cannot be used normally.
