ABSTRACT:
An electrical connector for establishing an interconnection between the contact pads of a printed circuit board and an electrical device. The connector includes a flexible circuit that is capable of being electrically coupled to a tester, driver, or some other external electrical device. The flexible circuit has a first side and an opposite second side and includes at least one metal layer and a plurality of electrically conductive contact bumps that are attached to and protrude from the metal layer along the first side. An expandable bladder is positioned adjacent the flexible circuit and exerts a force against the second side of the flexible circuit to cause the contact bumps to physically engage with the contact pads of the printed circuit board. A gas cylinder, pump, air compressor or other fluid pressure source is operatively coupled to the bladder for causing expansion of the bladder to effect the engagement of the contact bumps of the flexible circuit with the contact pads of the printed circuit board.
