ABSTRACT:
A novel metal core printed circuit board and a method of making it are described. The circuit board comprises a metal substrate, a patternable metal foil, and an insulating layer of thermoplastic resin whose glass transition temperature is exceeded during assembly under pressure to bond the resin to the metal substrate and to the foil by high temperature wetting. The circuit board also provides holes whose interior is lined with a resin united fusing to the resin in the insulating layer by high temperature wetting accompanied by pressure. The thermoplastic resin is a polyetherimide engineering plastic. The layers of the printed circuit board described above, including any additional layers of insulating resin and foil, may be bonded in a single step in a laminating press. The finished circuit board may be a structural component of a chassis, has good heat conductivity, good high voltage performance, is practical for high frequency transmission paths, is tolerant of the high temperature necessary for soldering, and has a high continuous service temperature.
