Abstract
An elastomeric connector couples the terminal pads of an LCD with corresponding terminal pads of a printed wiring board (PWB). Conductive elements in the connector are subject to skewing at such an angle that the LCD must be adjusted relative to the PWB to attain pad alignment. Sense pads on the terminal strips are coupled to contact pads and are arranged so that a continuity test on substantially opposed contact pads will verify pad alignment. In one embodiment, one sense pad is narrower than the terminal pads so that even marginal continuity will assure proper alignment of the terminal pads. In another embodiment, a pair of sense pads on either one of the LCD and the PWB is bracketed by a pair of spaced pads on the other such that continuity is evidence of non-alignment.
