Laser Equipment DPC Ceramic PCB Manufacturing Process-Bestceramicpcb

DPC Ceramic PCB is a type of printed circuit board made from ceramic materials with a copper layer directly plated onto the ceramic substrate. Based on the thin film technology, the metallization of the ceramic surface can be achieved by magnetron sputtering, and the thickness of the copper layer is greater than 10um by electroplating.

1. Material: Al2O3, AIN, ZrO2, Si3N4

2. Function: It has a lower coefficient of thermal expansion and higher conductivity, the small size makes it in a very narrow space.

3. Type: Thin film technology.

4. Custom service available.
