Latest Patents
Robert A. McGrath holds a patent for a high-speed multi-layer printed circuit board. This invention includes a via that has a conductive upper portion, a conductive lower portion, and an electrically insulating intermediate portion between the upper and lower portions. In one embodiment, the insulating intermediate portion of the via is provided by a non-platable layer of the circuit board, which may be comprised of PTFE. Vias with a continuous conductive coating can be formed through clearance holes in the non-platable layer, which are provided with a platable inner surface. This can be achieved by filling the hole with a platable material, such as epoxy resin, prior to laminating the board or by chemically conditioning the non-platable material to make it platable. Additionally, the insulating intermediate portion of the via has a narrower diameter than the conductive upper and lower portions.
