Thick Film Ceramic PCB

Thick film ceramic PCB is a circuit board made by screen-printing metal wiring layers onto ceramic bases, which are then solidified through high-temperature sintering. It is widely used in auomotive electronics and other fields where high circuit precision required are not so high, and the manufacturing process is simple, low cost and excellent thermal shock resistance.
