1. HS-W01S is applied to the metallization of alumina based high-temperature ceramics, the fabrication of heating plate electrode lead or metal electrode of high-temperature co fired ceramic process (HTCC). The products are lead-free and cadmium free environmental protection models, which meet RoHS standards; 2. HS-W01V is a metal filled electrode used in the metallization of alumina based high temperature ceramics and high temperature co fired ceramic process (HTCC). Excellent through porosity, no exposed bottom, concave and other defects. After high-temperature sintering, the silver layer has dense surface, strong conductivity, strong adhesion and good quality reliability. It does not contain harmful substances such as Pb and CD (in accordance with RoHS 2.0).
