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...

Why does PCB production need to be assembled?
In the general pcba processing, the circuit board production will carry out a splicing operation, whether it is the smt patch factory or the PCB design link, everyone needs to increase the board edge. The purpose of this process is to increase the patch processing Productivity.

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 ...

The shelf life and storage environment of the circuit board
Taking into account the differences in circuit board product technology and storage conditions, the printed circuit board should be used in time (recommended within 24 hours) after unpacking, and it is recommended to pre-dry before use, especially the PI substrate in the flexible circuit board If th...
