What are the reasons for pcb disconnection?
Do you know that to make a complete PCB, you need to go through many complicated processes? There will be some unqualified products in the PCB production process.
The common error is pcb disconnection. There are several reasons for pcb disconnection·
First, the film is not firmly attached to the ground and bubbles appear.
The second is the problem of the negative film caused by scratches or garbage.
Third, the development is blurred and unclear.
Fourth, the nozzle pressure is too high and the etching time is too long.
Fifth, the electroplating is uneven or the surface has adsorption force.
Therefore, if you want to find out what causes pcb board wire breakage, you should first look at the form of wire breakage, find out which process is the cause of the problem of PCB board wire breakage by analyzing the form of wire breakage, and then gradually check the possible causes in the production process.
