Abstract:
An apparatus that includes a plurality of metalized planes, one or more dielectric layers separating the plurality of metalized planes; and one or more conductive trenches connecting to at least one of the plurality of metalized planes.
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:
Formation of a mixed-material composition through diffusion using photo-thermal energy. The diffusion may be used to create electrically conductive traces. The diffusion may take place between material layers on one of a package substrate, semiconductor substrate, substrate for a printed circuit board (PCB), or other multi-layered substrate. The photo-thermal energy may be supplied by various devices, for example a YAG laser device, CO 2 laser device, or other energy source.

Abstract:
AN ARRANGEMENT OF PADS (14, 20, 22) WITH SELECTIVE VIA (24) IN PAD (14, 20, 22) FOR MOUNTING A SEMICONDUCTOR PACKAGE (12) ON A SUBSTRATE (18).IN ORDER TO STRENGTHEN THE SOLDERED BONDS, STANDARD PADS (14, 20, 22), WHICH HAVE A STRONGER BOND, ARE USED IN LOCATIONS OF GREATEST STRESS AND DEFLECTION. VIAS (24) IN PAD (VIP) ARE USED AT ALL OTHER LOCATIONS TO IMPROVE ROUTING ADVANTAGES DUE TO THEIR SMALLER SURFACE AREA.(FIG 3)
Abstract:
A REGISTRATION COUPON (20) IS PROVIDED FOR A PRINTED CIRCUIT BOARD (10) OR OTHER SUBSTRATE.THE REGISTRATION COUPON (20) MAY BE USED TO DETERMINE A HOLE-TO-OUTER LAYER FEATURE REGISTRATION AND A SOLDER MASK REGISTRATION. THE REGISTRATION COUPON (20) MAY INCLUDE A REGISTRATION HOLE PROVIDED ON THE CIRCUIT BOARD (10), A METAL PAD AND AN ANTI-PAD (40) PROVIDED ON THE CIRCUIT BOARD (10) ABOUT THE REGISTRATION HOLE (30), AND A SOLDER MASK (70) COVERING THE METAL PAD.(FIG 2)
Abstract:
An electronic assembly is disclosed. The electronic assembly includes a lower portion and a first elongate trace formed on an upper surface of the lower portion. The trace is covered by an upper portion, and an opening formed through an upper surface of the upper portion extends to the trace to expose a portion of the trace. A second elongate trace is formed on the upper portion. A portion of the second elongate trace positioned in the opening formed through the upper surface of the upper portion contacts the first elongate trace through the opening to form an electrical interconnection between the first trace and the second trace.
