  • Method of mounting a connector on a printed wiring board
    Patent number: 6209195
    Abstract: A surface mount connector that can be used for both single and double-sided PWB's. A telephone may have a printed wiring board with connector access from the bottom of the telephone and keypad activation from the top of the telephone. If a double-sided PWB is used, the connector is mounted to the bottom side of the PWB, while the keypad is mounted to the top of the PWB. The connector faces away from the PWB to provide access from below the telephone. If a single-sided PWB is used, the connector is mounted to the top side of the PWB, so that the keypad can also be mounted to the top side. The connector is placed, with connector access down, into an opening through the PWB. The connector extends down through the opening in the PWB with the leads of the connector remaining on the top side of the PWB. The leads of the connector are secured to pads on the top side of the PWB.
