    摘要: A process by which high frequency printed wiring board construction can be fabricated using smooth copper surfaces. A conductive, thin film polymer is plated on smooth copper surfaces of a core lamination. The polymer can be selected from a group of materials consisting of polypyrrole, polyaniline, polythiophene, and combinations thereof. The conductive polymer promotes adhesion between the resin polymer of the laminate and the smooth copper surfaces.

    摘要: A test apparatus for testing circuitized substrates such as PCB test coupons for thru-hole failure in which the substrate may be cooled to a temperature less than the ambient temperature surrounding the test apparatus housing in which the testing is accomplished. A method of testing substrates is also provided.

    摘要: A printed wiring board having a layered composite of metal planes and dielectric layers. At least one of the dielectric layers has a modulus lower than the modulus of the remaining dielectric material layers. A plating, extending through the layered composite, has a first land on a first external surface of the layered composite, a second land on a second external surface of the layered composite, and a barrel extending between the first land and the second land. The lower modulus dielectric material layer deforms during thermal excursions of the printed wiring board in such a way as to reduce the strains imposed on both the lands and the barrel of the plated through holes.
