    Abstract: A multilayer printed circuit board which reliably and economically marries conventional copper clad printed circuit board technology with polymeric conductors and insulators. Reliability is enhanced by forming all solder pads of copper, providing conductive tails on solder pads which are to be connected by polymeric inks, and ultimately forming a solder resist over all but the solder pads. As a result, polymer inks can be applied to both sides of the board, and the completed board can be subject to conventional solder dipping or wave soldering operations. According to one feature of the invention, a thin dielectric layer can be applied as intermediate to planar conductive layers which form a power plane having built-in distributed capacitance for decoupling.

    Abstract: 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.
