PSM-66 RIV-04 plug hole resin belongs to the halogen-free environmentally friendly products, the resin doesn't contain solvents and other harmful volatiles, can solve the problem of green oil blistering after lead-free tin spraying, this resin is suitable for selective resin plug hole process, resin plug holes out of the oil surface after the diffusion of a small, fast curing rate, to prevent the resin from entering the hole, can be a solution to the small spacing of plug holes bit problem. It has excellent high temperature resistance, no cracks, ultra-low diffusion, strong adhesion and chemical resistance.
Fields of application
PSM-66 RIV-04 hole plugging resin is used for inner and outer layers, HDI, POFV, normal through holes + back drilled holes, and highly selective plugging difficult products. This product is mainly used for FR-4 sheets, medium and high TG products.
