The present invention provides further a method of making a flexible circuit electrode array comprising depositing a polymer base layer; depositing metal on said polymer base layer; patterning said metal to form metal traces; depositing a polymer top layer on said polymer base layer and said metal traces; preparing at least one tack opening; and heating said flexible circuit electrode array in a mold to form a three dimensional shape in said flexible circuit electrode array.
Abstract:
An electronic assembly is made up of a number of rigid circuit boards manufactured on the same or different substrates or panels and with the same materials separated from each other electrically and physically. One of the rigid circuit boards has a comb (7) of printed tabs, or fingers, at the edge, which connects the assembly physically and electrically to a motherboard. Flexible wire jumpers (5) bridge the comb to form electrical connections between the boards. Both boards have printed circuit tabs placed in alignment to each other on both boards across a gap (21) which separates both boards. These tabs facilitate electronic interconnection of both boards via the flexible jumpers, which are groups or clusters of wires (4) separated from each other via a flexible insulator. A method for manufacturing the assembly is also disclosed, in which two boards (1, 2) are created by cutting gaps (21) from a substrate, leaving the two boards separated by a gap and connected by snap-offs (6). Once all the intended electronic components (9) and the flexible jumpers are soldered onto the boards, the boards are rotated, snapping them apart. After a desirable spacing between components of both boards is achieved, both boards are pinned together to maintain achieved proximity.
Abstract:
Transparent simulated components (4) are inserted into a test board (1) in an insertion machine for inserting such electrical components into printed-circuit boards at defined points. The simulated components are provided with scale-type markings (5). The test board has reference marks (3) with scales which are parallel with these scales and overlap said markings (4). The two vernier-type scales enable scale displacements to be read more clearly in the case of deviations from the ideal position.
