Product Description
Product Description
Thick-film Substrates on Ceramic Surfaces
Ceramic surface metallization is a process that creates a uniform metal coating on a ceramic substrate. Its primary purpose is to enhance the ceramic material's properties, including electrical conductivity, mechanical strength, and corrosion resistance. Thick-film metallization technology involves depositing conductive and functional layers onto the ceramic surface, creating components that combine the inherent properties of ceramic with the enhanced functionality of metallization.
Thick-film substrates are primarily used in low-cost, low- to medium-power applications, such as consumer electronics, sensors, and resistor networks.
