Abstract:
An apparatus is disclosed that may include a printed circuit board (PCB) and an electronics package may be disposed about the first surface of the PCB. The PCB may include a metal layer and a core, and, in some aspects, may include multiple cores interposed between multiple metal layers, and in some embodiments a backplane may be disposed along the core. The metal layer may be disposed on a core first surface. The metal layer may comprise metal or other conductive material suitable to define traces, which may be circuit paths for electronic components affixed to the PCB. In some aspects, the core may be electrically non-conducting, and may be thermally insulating, and, accordingly, inhibit the transfer of heat from the electronics package through the PCB. However, pins may be configured to pass through the PCB including the core from the core first surface to the core second surface to conduct heat generated by the electronics package away for dispersion. In some embodiments, the pins may pass into the backplane. A pad may be disposed between the electronic package and the core in some embodiments, the pins passing into the pad.

This invention provides a bending-type rigid printed wiring board that can easily realize mounting of electric components (can realize a plated circuit having high productivity and assembling properties), can realize space saving, and can realize easy production. The bending-type rigid printed wiring board comprises a hard cure material (1) with a space part (1A) inserted thereinto. A heat-resistant resin layer (31) is stacked on the surface of the hard core material (1) and, at the same time, on the upper surface of the space part (1A). A heat-resistant resin layer (32) is stacked on the backside of the core material (1) except for the space part (1A). Further, a conductor layer (4) is stacked and fixed through the heat-resistant resin layers (31, 32). The conductor layer (4) has been etched to form a circuit.
Abstract:
Methods and devices are provided for repairing a damaged contact pad that is located on a first surface of a printed circuit board and connected to a via that passes through the circuit board. According to the method, a countersink hole is created in the first surface of the printed circuit board in a location that is substantially centered on an axis passing through the via, and a replacement structure is inserted into the countersink hole. The replacement structure has a stem portion, a head portion, and a shoulder portion that connects the stem and head portions, with the angle of the shoulder portion substantially matching the angle of the shoulder of the countersink hole. The stem portion of the replacement structure is permanently attached to sidewalls of the via so as to electrically couple the head portion of the replacement structure to the via.
