Conductive adhesive for use in a circuit board

摘要

A double-sided printed circuit board and a method for making the circuit board. The circuit board includes a metal support that functions as both a heat sink and a ground plane. The circuit board contains a dielectric having first and second conductive foil platings on opposing sides of the dielectric. Prior to bonding the first foil plating to the metal support with a conductive adhesive, a standard protective coating on the first foil plating, which typically remains on the foil plating in conventional practice, is removed in order to expose a bare surface of the first foil plating. The exposed bare surface of the first foil plating is then bonded to the metal support before any substantial oxidation or a build up of impurities on the first foil plating surface can occur.
