What Is Selective Wave Soldering?
Jun 21,2024
What is selective wave soldering? Selective wave soldering, also known as robot soldering, is a special form of wave soldering invented to meet the development requirements of through-hole component soldering. Selective wave soldering generally consists of three modules: flux spraying, preheating and welding. Through the equipment programming device, the flux spraying module can complete the selec...

SMT Component Letter Codes
Jun 20,2024
During the SMT assembly process, we will come into contact with a variety of materials. Although the error of materials is a low-level error, it is not easy to identify because there are too many and too complicated materials involved, and the current development trend of materials is getting smaller and smaller. At the same time, PCB boards are getting smaller and smaller, and the distance betwee...

What Is A 4-Layer PCB?
Mar 05,2024
A PCB is a board of non-conductive material, such as fibreglass or composite epoxy, with a layer of conductive copper traces etched onto its surface. These traces form circuits that allow electrical signals to flow between components. An important aspect of printed circuit boards is the concept of layer count. Layer count refers to the number of conductive layers in a PCB, which determines its com...
