What is the cause of the disconnection of the PCB board?

To make a complete PCB board, you need to go through many cumbersome and complicated processes. If there are some operational errors in the PCB board production process, it will lead to quality problems in the final product board that does not meet the product requirements. The common PCB board disconnection problem will affect the realization of the circuit board function.

So, what is the cause of the PCB disconnection? The following are some of the reasons that lead to the disconnection of the PCB board sorted out by the editor:

1. The process of pasting: the pasting is not strong, there are bubbles, and if it is wet, there will be garbage pollution.

2. Exposure process: Problems caused by scratches or garbage on the film, including problems with the exposure machine, insufficient exposure, etc.

3. Development process: the development is fuzzy and unclear.

4. Etching process: The nozzle pressure is too high and the etching time is too long.

5. Electroplating problem: The electroplating is uneven or the surface has adsorption force during electroplating.

6. Improper operation: During the circuit board production process, the circuit board was scratched and broken due to improper operation.

What is the cause of the disconnection of the PCB board? First, look at the form of the disconnection. Through analyzing the form of the disconnection, find out which process the problem caused the PCB board disconnection problem, and then gradually check the possibility of the production process. Investigate the cause of the occurrence.
Through the above description, I hope it will be helpful for you to analyze the reasons for the disconnection of the PCB board.
