Disclosed is a system that determines whether pins of electrical components such as connectors, switches, and sockets are present and properly soldered to a printed circuit board. The system uses an oscillator which supplies a signal, typically ten kilohertz (10 kHz) at 0.2 volts, to the pin under test. A conductive electrode is placed on top of the component. The electrode is connected to a current measuring device. Another pin of the component is connected to a common signal return.
