    摘要: The Printed Circuit Board (PCB) has connectors which each include a terminal part and a connector pin. The terminal part is formed in one end of the PCB and is provided with a terminal hole. The connector pin is configured such that one end thereof is inserted into the terminal hole, and the remaining end thereof extends to protrude outside the terminal hole and is also bent several times, thus forming a contact part that is elastically deformed, and electrically connected to a pad part provided in a target PCB for connection. Thus, a desirable signal transmission characteristic is guaranteed, so that the reliability of electronic devices using the PCB can be improved and the manufacturing cost can also be reduced.
