印制插头是印制电路板的一个有机构成部份,板上的电讯号通过它与电子、通讯设备的其它部份相沟通,所以一般都需在它的表面上镀一层金,以获得低而稳定的接触电阻,良好的耐磨损
The printed plug is an integral part of a printed circuit board through which the electrical signals on the board communicate with the rest of the electronics and communications equipment so that it is generally necessary to apply a layer of gold on the surface to obtain Low and stable contact resistance, good wear resistance
