IPC: B28D5/00
Filed: 1990-11-27
Abstract: PURPOSE:To enhance the capability of a device by mounting two dicing blades and aligning the central line of the two blades during the dicing operation with the same straight line. CONSTITUTION:Two blades 1 and 2 are aligned with a dicing central line 3 on the same straight line.
