The main core point of SMT process

Among SMT manufacturers, especially those with PCB labor and materials, if they can manage all the production processes in production, they can provide customers with high-quality products. But after removing some factors, we have also sorted out the main problems in smt patch processing. Among them...

PCB etching process and process control

 In the processing technology of the outer circuit of the printed circuit board, there is another method, which is to use the photosensitive film instead of the metal coating as the resist layer. This method is very similar to the inner layer etching process, and you can refer to the etching in the ...

PCB circuit board CTI value, grade, model and test comparison

The tracking resistance of PCB copper clad laminates is usually expressed by the Comparative Tracking Index (CTI). Among the many properties of copper clad laminates (copper clad laminates for short), tracking resistance, as an important safety and reliability index, has been increasingly valued by ...
