IC Surface Mount to Breadboard Adapters

Base Connectors
Base connectors provide a compact way to connect a printed circuit card or other device to SMT board pads or test sockets. The connectors consist of a plastic body mounted with pin receptacles that match Aprilog surface mount bases SMT base connectors have female receptacles that mate with matching surface mount bases. The female pin receptacles press fit easily into the base connector plastic, and are shipped loose. This makse mounting the base connector easy. Align the holes in the PCB with the base, and receptacles slide into their holes and PCB pad hole. The receptacles are barbed so that they will not slip out of the plastic body.
