US 2010/0149738 A1 · PRINTED CIRCUIT BOARD ASSEMBLY

Abstract

A PCB assembly includes a PCB. The PCB includes a detecting pad, a detecting voltage terminal and the controller. The detecting pad includes an accessing layer and a grounding layer. The grounding layer is connected to the ground. The accessing layer is electrically insulated from the grounding layer. The detecting voltage terminal is connected to the accessing layer of the detecting pad. The controller is connected to the accessing layer of the detecting pad. When the accessing layer is not connected to the grounding layer, the controller receives a high level voltage signal from the detecting pad. When the accessing layer is connected to the grounding layer, the controller receives a low level voltage signal from the detecting pad, and therefore the PCB is capable of determining what computer system the PCB is coupled with.
