Silver Paste for LTCC

Silver paste for LTCC (low temperature co-fired ceramic) is a conductive material formulated to deliver excellent printability, high electrical conductivity, and strong adhesion during multilayer circuit fabrication. Designed to withstand LTCC co-firing temperatures, it ensures stable sintering, forming dense and uniform silver networks within the ceramic layers. This paste enables precise conductor patterns with smooth edges and consistent thickness, supporting reliable signal transmission and long-term device stability in applications such as RF modules, sensors, antennas, and embedded passive components.
