ABSTRACT:
An edge connector (10) and method of assembly for making electrical contact with contact pad areas (11) along an edge of a circuit card (12), such as a thin film circuit or thick film circuit. The connector includes a spring clip (20) having a set of three spring fingers (21-22-23) projecting therefrom and offset to define a space (24) between the fingers into which the circuit card can be inserted (A) to pre-assemble the card with the clip. The central tine (22) is crimped about a solder preform (30) so as to deform the preform into an hourglass configuration in which the ends of the preform contact the surface of the card. The preform is then melted to form a solder joint (50) bonding the connector to the circuit card.
