If the metal part of the PCB board is patina, it is most likely because there is no coating conformal coating, metal copper and water vapor, oxygen together caused by chemical reactions.Coating conformal coating on PCB circuit board is a very important and common process in PCBA industry.AVENTK as a UV glue manufacturer, after understanding the moisture problems of PCB circuit board, according to the requirements and problems of PCB circuit board, combined with the convenience of UV curing and high quality performance, developed and produced a UV moisture double curable three anti adhesive - 5001 series UV moisture double curable conformation coating.
