摘要： A substrate for a plurality of electronic assemblies includes a strip of printed circuit board (PCB) material including a surface and a plurality of segments. Each segment is adapted to receive at least one electronic component and is arranged to be singulated into a plurality of individual electronic assemblies. Each segment has a perimeter portion located generally about the periphery of the segment, with the surface being covered with a solder mask, except for the perimeter portion.

摘要： A stackable modular cabinet having modular, interlocking side units which allow cabinet dimensions to be tailored both vertically and laterally to user needs while also providing the strength and stability to support heavy equipment such as electronic subassemblies. Each side unit has a pair of mating flanges with apertures for receiving and retaining fastening pins that interlock to the fastening pins of a different side unit when the respective flanges of the two side units mate. The interlocked fastening pin structure forms unified rods which extend the full height of the cabinet and which cooperates with the intervening side unit flanges. Each side unit further has re-enforced, double-sided bracket structures at opposing ends which, in combination with the pin structure, provides an unusual amount of strength to the modular cabinet.

摘要： An integrated circuit package which includes an integrated circuit that is attached to a first side of a substrate. The package may also have a solder ball and a heat slug that are both attached to a second side of the substrate. The heat slug and solder ball can be attached to a printed circuit board. The heat slug can provide a thermal path from the substrate to the circuit board which has a relatively wide area. The wide area reduces the thermal impedance and the junction temperatures of the integrated circuit for a given amount of heat.

摘要： An integrated circuit package including a substrate, an integrated circuit, and an encapsulant. The substrate has two opposing surfaces and an opening that extends between the two surfaces. The integrated circuit is mounted to the substrate substantially centered over the opening such that a portion of the opening is left uncovered by the integrated circuit. The encapsulant encapsulates the integrated circuit with a portion of the encapsulant extending between the two surfaces of the substrate and attached to the lower surface of the integrated circuit.
