Abstract

A circuit board edge member includes an elongated body of electrically insulative material having front, back and inner wall members and a plurality of pairs of contact elements seated with one of each pair between the front and inner walls and the other of each pair between the back and inner walls. A tongue is integrally attached to the inner wall and extends from the body in line with a circuit board receivable at a circuit board seat formed in the body. The contact elements are formed with a gold inlay solid phase bonded to a portion of the contact element which is received on opposite faces of the tongue. The tongue has a reverse taper and may be slotted to provide polarization. Mounting ears may be provided on opposite ends of the base to facilitate attachment of the edge member to a circuit board using conventional screw fasteners or snap in devices. The edge member is assembled by inserting contacts while still attached to a carrier web in two opposite directions, severing the contacts from the carrier web and bending their pin ends to form two rows of contact pins receivable in two rows of holes in the circuit board. A flexible, U-shaped mask is placed over the tongue to prevent contamination during wave soldering.
