Circuit board laminate

摘要

A circuit board laminate comprising a circuit board (8) and a baseplate (2). The baseplate (2) is machined to provide flat top projections (4) having chamfered edges (16). The circuit board (8) having etched copper tracks is soldered to these projections providing improved mechanical and electrical connections. An improved grounding connection is also proposed, whereby a plated through hole (20) in the board is disposed above the chamfered edges of the projection.
