MACHINING JIG FOR MACHINING SIDE SURFACE OF PRINTED CIRCUIT BOARD AND SIDE SURFACE MACHINING METHOD USING THIS JIG

摘要

PROBLEM TO BE SOLVED: To enable a burr removing machining operation to be efficiently carried out for many printed circuit boards under normal temperature and eliminate a post-treatment process. ;SOLUTION: A main body 1 of a disc-like jig having a stud 7 projected on a bottom surface is provided with a plurality of slits 3 and then printed circuit boards W are set within the slits. An upper lid 2 is placed on the main body 1 of the jig, the main body 1 of the jig is rotated on a lapping machine while the printed circuit boards W are being pressed down and then a side surface of each of the printed circuit boards W is deburred.;COPYRIGHT: (C)1997,JPO
