Printed circuit board scrap removal and printed circuit board fabrication process

摘要

Circuit boards are formed within the boundaries of an insulative sheet or panel such that the panel may be automatably processed. The periphery of each printed circuit board is defined by at least a plurality of score lines which do not extend to the edge of the sheets and may include also uncut and/or unscored areas to provide stability to either the sheet or segments of scrap material, lending rigidity to the sheet. Following complete fabrication of the printed circuit board, the sheet is cut by a routing process to extend selected score lines to the edges of the sheet to destroy the integrity of the frame of scrap material surrounding the printed circuit boards.
