EDGE CONTACTS OF CIRCUIT BOARDS, AND RELATED APPARATUS AND METHODS

摘要

In some embodiments, flat electrical contact pads may be fabricated along a routed edge face of a printed wiring board (PWB). Some embodiments of the edge pads may, for example, be perpendicular to a plane of the printed wiring board. In some embodiments, the edge pads may be of a specified length and/or width. Some embodiments of the edge pads may, for example, have a surface finish suitable for soldering and/or for direct contact interconnections. In some embodiments, the edge pads may, for example, be configured for electrical connection to an adjoining device (e.g., PWB) with mating pads to form a tiled array configuration of interconnected devices (e.g., PWBs).

主权项

1. A circuit board, comprising:
a plurality of layers stacked in a thickness direction; a peripheral edge having a first thickness in the thickness direction; and an edge contact disposed at the peripheral edge of the circuit board, the edge contact having a second thickness in the thickness direction, the second thickness being less than the first thickness.
