Product Features

Product Description:
EP 8108 is a single-component, modified epoxy resin adhesive used for BGA (Ball Grid Array) and CSP (Chip Scale Package) bottom filling processes. It forms a uniform, defect-free bottom fill layer that effectively reduces the mismatch in the overall thermal expansion properties between the silicon chip and substrate, as well as the impact caused by external forces. Once cured by heat, the adhesive improves the mechanical strength of the chip connection and enhances the product's performance, thereby extending its lifespan.
