A PCB header is a type of connector that is used on printed circuit boards, most commonly motherboards to allow you to connect other accessories or cables into a single connector on the circuit board. They come in different shapes and sizes and can be mounted in various ways. The MC & MCV series are all recommended to be wave soldered onto the PCB.
