SRB001 Adhesive sheet material

SRB001 adhesive sheet material is a semi-CURED SHEET BASED ON CERAMIC powder filled THERMOSETTING resin and PTFE composite system, used for pressing and bonding multi-layer circuit board quality inspection. SRB001 adhesive sheet material can be used in millimeter wave radar, antenna, car collision avoidance radar and other fields. It can realize the bonding between multilayer substrates at low pressing temperature, and can be used for pressing multilayer circuit boards of various substrates such as PTFE, epoxy, LCP and hydrocarbon resin.
