Abstract

The invention relates to a chip support coil band. Wherein, it mainly comprises a main body, dual packing units and dual counting marks; said packing units and counting marks are arranged at least one side edge of main body and outside the packing units; said packing unit has fixed first distance; the counting mark has fixed second distance; the first distance is positive integer times than the second distance, while the second distance is 0.50-3.97mm, to increase the packing unit and reduce the coil band waste.

Description

technical field [0001] The invention relates to a chip carrying tape, in particular to a chip carrying tape with side counting marks. Background technique [0002] The existing known chip carrier tape has a lead pattern, which can be used in TCP (Tape Carrier Package, tape carrier package) or COF (Chip-On-Film, chip-on-film) packaging, and has two sides on both sides of the tape. Sprocket holes for transmission. The current general specification is tape with a pitch of sprocket holes of 4.75mm. If the sprocket holes are directly used for packaging and counting, there will be a waste of reel material. [0003] Please refer to FIG. 1 , which is a partial top view of a conventional chip carrier tape. The conventional chip carrier tape mainly includes a tape body 11, and a plurality of equidistant packaging units 12 are arranged in the tape body 11, and the packaging units 12 have a first pitch P1. Each packaging unit 12 can be bonded with a chip to form a chip package (not s...
