Electrical contact for a printed circuit board
摘要:
An electrical contact that is mounted on a printed circuit board to provide an electrical connection to the printed circuit board. The contact has the structural integrity of a through-hole component with the capability of being soldered to the circuit board using a surface mount reflow process. The contact includes a pair of elongated, conductive pins with a base disposed therebetween, and a solder preform supported on one of the conductive pins adjacent the base. The pin supporting the solder preform is insertable into a plated-through hole on the circuit board so that the solder preform can be reflowed into the hole along the pin to form a solder joint between the contact and the hole. The contact may include a retainer to secure the solder preform to the pin and the end of the base adjacent the pin may be beveled to facilitate gas ventilation from the hole during the soldering process. The base may be configured so that it can be grasped with a test instrument or support a wire connection to the contact. The contact may be symmetrical so that the solder preform can be supported on either conductive pin.
