The reason for PCB surface blistering is actually the problem of poor adhesion of the board surface: PCB blistering is caused by the copper plating process in the production process of circuit boards, and is also one of the common quality defects. Due to the complexity of circuit board production process and process maintenance, especially in the chemical wet treatment process, it is difficult to prevent surface blistering defects. The reason for PCB surface blistering is actually the problem of poor adhesion, which can also be said to be a surface quality issue of the board surface;
