PCB Pins and Receptacles

PCB pins and PCB receptacles are electronic interconnect devices for printed circuit boards (PCB). PCB pins are male connectors. PCB receptacles are female connectors. Both are made of metallic elements or alloys and available in a variety of shapes and sizes. PCB pins are terminals on components which use through-hole technology (THT), a mounting style which inserts leads through holes in the board and then solders the leads in place on the opposite side. Surface mount technology (SMT), a popular alternative to processes that use PCB pins, adds components by soldering component leads to the top surface of the board. With through-hole connections, pin receptacles provide an electrical path from the component lead through the contact via the terminal or housing. The inner contacts or clips of a PCB receptacle feature a multi-line or multi-finger style that can accommodate round, square, or rectangular component leads.

Suppliers of PCB pins and PCB receptacles offer many different types of PCB pins. Examples include double-tail header pins, edge-mount pins, nail-head pins, solder-cup terminal pins, slotted terminal pins, solder-mount PCB pins, solderless press-fit PCB pins, spring-loaded pins, surface mount pins, swage terminal pins, turret terminal pins, wire crimp pins, wire wrap terminal pins, and wire termination pins. Most PCB pins are single-ended or double-ended and have a plated shell. Contact materials include brass alloys, phosphor bronze, tellurium copper, beryllium copper, and beryllium nickel. Copper, lead, gold, silver, tin, nickel, and palladium are used as plating materials. Pin diameter, dimensional accuracy, board thickness and mounting-hole size are important specifications to consider. Some suppliers specify PCB pins in inches (in) or fractions of inches. Others use metric measurements such as millimeters (mm).

Suppliers of PCB pins and PCB receptacles offer are many different types of PCB plugs. Examples include receptacles with or without a standard tail, receptacles with a wire-wrap tail, receptacles with a turret, surface mount receptacles, and wire crimp or termination receptacles. PCB receptacles that are designed for molded plastic or drilled circuit boards may use a barb for improved retention. A knurled shell is sometimes used to provide retention without rotation. Shells with through-holes are designed for boards with long pins, or PCBs that require stacking. Lead size, current rating, board thickness, dimensional accuracy and mounting-hole size are important specifications to consider when. Contact materials for PCB receptacles include brass alloys and beryllium copper. Tin, lead, and gold are common plating materials. Some suppliers specify PCB receptacles in inches (in) or fractions of inches. Others use metric measurements such as millimeters (mm).
