Abstract
Abstract A circuit pattern on the surface of a printed circuit board is used as a guide and connection circuit for closely spaced contacts of a connector to be connected to the circuit board. The contacts of the connector are closely spaced and possibly would not contact the connection pads or might be located between connection pads because of the close spacing of the contacts. The guides formed from circuit patterns accurately guide the connector to the connector pads on the circuit board and place each contact over its respective circuit connection pad.
