<p>The flexible connector for high density circuit applications comprises a multi-layer flexible substrate (10) upon which are formed a plurality of contact pads (12), in a density required by a particular application. This density may exceed two hundred contact pads per square inch. Contact pads (38) of similar size and configuration are formed on the surface of another device, i.e., circuit board (40), and provision made to align the contact pads (12) of the connector with those (38) of the circuit board (40). Micro-pads (20) are formed on the surface of the contact pads (12) on the connector such, that when the connector is brought into contact with the circuit board (40), and sufficient pressure is applied, the micro-pads (20) make actual electrical contact with the pads (38) of the circuit board (40). Since the total surface area in contact, namely the sum of the surface areas of the micro-pads (20), is a small fraction of the total area of the connector, a large pressure is provided at the electrical contact interface even when low pressure is provided to the connector as a whole. <IMAGE> <IMAGE></p> |
