How It Works

The working principle of the surface mount ceramic is to provide a solution for electronic components to be directly mounted on PCBs. Its main body is formed by co-firing multilayer alumina ceramic at high temperatures, with standardized metallization pads on the ceramic bottom surface, achieving electrical connection with internal component mounting surfaces through the ceramic interior.

Chips are fixed within the cavity using conductive adhesive or eutectic soldering, and connections between components and the internal ceramic metallization patterns are achieved through wire bonding. During use, the pads on the package bottom can be directly mounted on PCB pads through reflow soldering, achieving electrical interconnection and mechanical fixation. The high insulation resistance of the ceramic material ensures electrical isolation between pads.
