Apparatus for aligning a printed circuit board (PCB) relative to a datum line defined between two pins fixed to a supporting member. One pin is cylindrically shaped and the other is shaped in the form of a frustum of a cone. Two aligning holes are provided on the PCB spaced apart by a distance slightly different from the spacing between the pins so that with one hole over the cylindrical pin, the edge of the other hole rests on the sloped side of the other pin. As the PCB is pressed against the supporting member between the two pins by securing means, the PCB is sprung, and the stored force of the sprung PCB presses the edges of the PCB holes against the pins for precise alignment relative to the datum line between the two pins.
