Abstract: A protective coating of insulating material is formed around a clearance hole in a conductive layer of a printed circuit board, so that the conductive material in a via within the clearance hole will not contact the conductive layer and create a short circuit. In one embodiment, the protective coating is sufficiently hard to deflect a drill bit being used to drill the via hole, thus protecting against misregistered drilled holes.

Abstract: Methods to shield conductive layer from via. A protective coating of insulating material is formed around a clearance hole in a conductive layer of a printed circuit board, so that the conductive material in a via within the clearance hole will not contact the conductive layer and create a short circuit. In one embodiment, the protective coating is sufficiently hard to deflect a drill bit being used to drill the via hole, thus protecting against misregistered drilled holes.

Abstract: An arrangement of pads with selective via in pad for mounting a semiconductor package on a substrate. In order to strengthen the soldered bonds, standard pads, which have a stronger bond, are used in locations of greatest stress and deflection. Vias in pad (VIP) are used at all other locations to improve routing advantages due to their smaller surface area.

Abstract: A printed circuit board and a system and method of embedding conductor channels into a printed circuit board. These conductor channels are used to provided increased power to circuits on the printed circuit board, provide shielding for these circuits and provide communications for these circuits. These conductor channels are created by ablating dielectric layers in the printed circuit board and depositing a conductive material therein.

Abstract: A standoff device provides predetermined control of a standoff distance between electrical components mounted together with opposing conductive grid array patterns. In an embodiment, a predetermined electrical function is provided by the device to at least one of the electrical components. The standoff device comprises a plurality of rigid one-piece standoff pins which, in an embodiment, contains one or more stops which buttress against the electrical components to serve as a distancing control structure. In an embodiment, the standoff device is integral with one of the electrical components.

Abstract: A registration coupon is provided for a printed circuit board or other substrate. The registration coupon may be used to determine a hole-to-outer layer feature registration and a solder mask registration. The registration coupon may include a registration hole provided on the circuit board, a metal pad and an anti-pad provided on the circuit board about the registration hole, and a solder mask covering the metal pad.

Abstract: Standoff arrangements to control distance and provide electrical function.

Abstract: An apparatus that includes a substrate, one or more via in pads in the substrate; and one or more vents in at least one of the one or more via in pads, the one or more vents connecting an outer diameter of at least one of the one or more via in pads to a diameter larger than the via.
