Abstract:
A technique comprising: forming a plurality of smaller substrates from one or more larger substrates by a reduction process according to which there is some possible variation size between the smaller substrates within a variation range; and, in advance of said reduction process, providing said one or more larger substrates with one or more detection marks whose size and location are selected such that after the reduction process each smaller substrate includes a portion of at least one of said one or more detection marks, said portion having one or more edges that coincide with at least a part of one or more edges of the smaller substrate whatever actual size the smaller substrate has within said variation range.
Abstract:
A connector assembly includes a substrate and a connector. The substrate includes a ground layer and a trace layer. The substrate defines a substrate edge, and the ground layer defines a ground edge. The connector is mounted on the substrate such that a portion of the connector overhangs the substrate edge of the substrate. The connector includes a first signal contact that defines a mating portion, a mounting portion, a first transition portion connected to the mating portion, and a second transition portion connected to the first transition portion and the mounting portion. The first transition portion of the signal contact at least partially crosses the ground edge such that a gap is defined between the ground edge and the first transition portion and a substantial portion of the second transition portion extends over the gap when the electrical connector is mounted on the substrate.

Abstract:
A system comprises an upper printed circuit board (PCB) that comprises a notch. The system further comprises a lower PCB that electrically couples to the upper PCB, is disposed below the upper PCB and comprises circuitry that protrudes through the notch.
Abstract:
A USB device comprising a printed circuit board enclosed in a thermoplastic resin and a method for preparing said device. In one embodiment, the method comprises: a) Preparing a plurality of printed circuit boards in the form of a panel comprising a matrix of rectangular pieces which define individual printed circuit boards; b) Forming V-shaped scores in the boundaries between said individual printed circuit boards at both sides of said panel so as to define straight trenches on opposite sides of said panel; c) Cutting said panel in correspondence of said trenches so as to obtain a plurality of printed circuit boards having chamfered edges; and d) Encapsulating said individual printed circuit boards with a thermoplastic resin. In the device of the invention, said printed circuit board has a substantially rectangular shape with chamfered edges, said thermoplastic resin forming a bond with said printed circuit board in correspondence of said chamfered edges.
