Abstract
Abstract An electronic-parts mounting board frame sheet includes a plurality of electronic-parts mounting board frames serially coupled into a single sheet. Each frame includes an electronic-parts mounting board with an insulating substrate, grouped leads protruding from the insulating substrate, an outer frame integrally formed with the grouped leads, and pilot holes, located in the outer frame, for indicating the positions of the grouped leads of the electronic-parts mounting board. Further, the grouped leads and the outer frame of each electronic-parts mounting board frame are integrally formed.
