Description

Technical Field

[0001] The utility model relates to the technical field of jigs, in particular to a vacuum blanking jig for chips. Background Art

[0002] Existing large-scale chips are cut into individual chips using CNC milling machines. However, a base film must be attached to the bottom surface of the large-scale chip before processing. Otherwise, the milling cutter will knock the chips off during the cutting process, damaging the chips.
