Excellent PCB design layout can save production costs, which can both make the circuit running well and realize the heat dissipation. Simple design layout can be done manually, but complex design layo...

3D printer now promotes the rapid development of the domestic product. In fact we can manufacture prototype circuit board with the traditional iron and a laser printer. What we only need to do is inst...

We should first determine the corresponding circuit board structure according to the size of the circuit board size and electromagnetic compatibility requirements before designing multilayer PCB. Afte...

On the issue of printing circuit board, we can not only depend on manufacturers but also use CNC machine tool to engrave circuit board. CNC machine tool is mainly used for the turning of machine parts...

Silkscreen of PCB is the text layer of PCB, which is at the top of PCB and used to make notes. The silkscreen layer includes the top layer and the bottom layer. They are the uppermost and lowermost la...

The printing work station is the first and most important work station in the process of SMT, the printing quality determines the quality of SMT to a great extent, so it is very important to understan...

In addition to allow the manufacturers to play sample, we can also own a DIY PCB, and the success rate of homemade PCB is higher. The photographic method is the main principle of design. We divide thi...

  PCB is an important part of electronic products, which exists in a large number of electronic waste. Therefore, study of recovery technology in metal and non-metal has vital significance. ...
