Abstract:
The present invention discloses a USB application device including a body, a circuit board, a plurality of first electrical pins and a plurality of electrical elements. The circuit board is disposed in the body. The plurality of first electrical pins are disposed on the circuit board and expended to the body such that the plurality of first electrical pins are partly exposed to the body. A space is formed between the plurality of first electrical pins and circuit board such that the plurality of electrical elements can be disposed on the space. The length of the circuit board therefore becomes shorter, and the volume of the USB application device is reduced.

Abstract:
A signal processing module (100) can be manufactured from a plurality of composite substrate layers (104-106), each substrate layer includes elements of multiple individual processing modules. Surfaces of the layers are selectively metalicized to form signal processing elements when the substrate layers (104-406) are fusion bonded in a stacked arrangement. Prior to bonding, the substrate layers are milled to form gaps located at regions between the processing modules. Prior to bonding, the leads (110) are positioned such that they extend from signal coupling points on said metalicized surfaces into the gap regions. The substrate layers (104-106) are then fusion bonded to each other such that the plurality of substrate layers (104-106) form signal processing modules (100) with leads (110) that extend from an interior of the modules into the gap areas. The individual modules (100) may then be separated by milling the substrate layers to de-panel the modules.

Both the power device (21) and the circuit component (22-25) are mounted on the printed board (31) by using a connection terminal (41) which protrude from the resin mold unit (40). According to the vehicle electronic control unit, noise and efficiency of the circuit can be improved because a loop of large current can be reduced.
Abstract:
The present invention is a method and structure which produces extremely thin, electrically conductive epoxy bonds (24) between two substrates (12, 14). Copper microspheres (26), having an average diameter of about 2 microns are bound in an epoxy layer (28) which bonds two substrates (12, 14) together. The microspheres (26) make electrical contact between the substrates (12, 14) while providing inter- sphere gaps which are filled with the epoxy which actually bonds the substrates (12, 14) together.
