    Abstract: The present invention relates to a packaging substrate with electrostatic discharge protection. Each of the mold gates on the substrate is electrically connected to the first copper-mesh layer on the periphery of a top side of the substrate. When static electricity is generated during the molding process, static electric charges will be conducted from the mold gate to the first copper-mesh layer. The static electric charges are collected and restricted to a capacitor formed by a first copper-mesh layer, a dielectric layer and a second copper-mesh layer, and are discharged via a metal pad and supporter. On the other hand, the static electric charge is conducted via the first copper-mesh layer, a through hole, the second copper-mesh layer, the metal pad to the supporter. Therefore, basing on capacitor effects or conductive effects, the static electricity generated during the molding process can be safely conducted away from the substrate, preventing the dies to be packaged from damage due to electrostatic discharge so as to raise the yield rate of semiconductor package products.

    Abstract: A power semiconductor module achieves high isolation strength from a base through selectively positioning a plurality of metal coatings on first and second surfaces and positioning edges of the plurality to beneficially reduce the field strength tangentially to a selected position, especially in a defined critical region directly adjacent a metal coating edge on a first surface opposite the base. This design results in regions which beneficially allow field lines to extend without functional detriment. The beneficial position selection is is achieved by means of an optimization process in which the tangential components of the field strength beside the first or second metallization edge reach identical values.

    Abstract: Construction of printed circuit boards (PCBs) containing electromagnetic shielding and conductive tubes forming signal lines and/or waveguides. The method of construction calls for forming of grooves through layers of the PCB and coating the interior surfaces of these grooves with conductive material. These conductor-coated groove walls serve as conductive surfaces between embedded conductive surfaces on different layers. The conductive surfaces thus joined form a continuous electrically conductive surface that can be configured to act as an electromagnetic shield. Such conductive surfaces may be configured with internal conductors to act as a signal line, or without internal conductors to act as a waveguide.
