Defoaming agents are used in PCB substrate cleaning, PCB water treatment, film withdrawal, etching, development and sewage treatment (the whole process of PCB).In particular, the dry film process in PCB production is to remove the unexposed dry film by developing. The dry film is photosensitive insulating resin and the developer is sodium carbonate solvent. Due to the continuous dissolution of the dry film, the developer in the system circulation spray process produces a certain amount of foam, foam to a certain extent will affect the quality of development, causing inconvenience to the production!
