Metal core circuit plate - has copper plate with through hole contacts sandwiched between insulating plates

摘要

A copper plate (1) acts as the so called metal core for the circuit plate. The plate has a pattern of holes formed (2,3) that serve for providing connectors from one side of the plate to the other. On both sides of the plate are plates (6) of plastic (6). Layers of impregnated material (T) are located within a frame (8) that is produced of a synthetic material and is subjected to a heated forming process. Material flows into the holes in the core plate. ADVANTAGE - Simplifier process of manufacturing circuit plates.
