Problems solved by technology

[0004] The main purpose of the present invention is to increase the number of circuit layouts without changing the hole spacing between the drive holes and the length of the circuit board tape; Maintain the arrangement at equal intervals to solve the problem in the prior art that the subsequent process cannot be performed due to the variation in the distance between the jointed transmission holes caused by the operator's indeterminate cutting position

Abstract

The invention relates to a circuit board tape and a butt joint method thereof. The circuit board tape comprises a plurality of substrate units, each substrate unit is provided with a transmission hole setting area, a circuit layout area and a butt joint mark, the transmission hole setting area is provided with more than three transmission holes, the number of the transmission holes is an odd number, the circuit layout area is provided with a first circuit layout and a second circuit layout, and the butt joint mark extends to form a virtual line. The virtual lines are located between the first circuit layout and the second circuit layout, an odd number of transmission holes are formed between the virtual lines of the adjacent substrate units, and the unqualified substrate units are cut off along the virtual lines of the different substrate units, so that the circuit board winding tape is broken into a front winding tape part and a rear winding tape part; and after the front winding tape part and the rear winding tape part are jointed, a first circuit layout arranged on the front winding tape part and a second circuit layout arranged on the rear winding tape part form a composite circuit layout area.

Description

technical field [0001] The invention relates to a circuit board tape and its docking method, in particular to a circuit board tape that can be docked after cutting unqualified substrate units and its docking method. Background technique [0002] In the existing known circuit board tape design, a plurality of circuit layouts are arranged on the substrate, and a plurality of transmission holes are provided on both sides of the substrate, and each of the two sides of the circuit layout corresponds to an even number of transmission holes. And the pitch between the transmission holes must match the tooth pitch of the transmission member (such as a transmission wheel or a transmission bar), so that the transmission member can drive the substrate to carry out processes such as bonding wafers and gluing. [0003] However, in the inspection step, the area with the unacceptable circuit layout is cut off, so that the circuit board reel is formed into a front reel and a rear reel, and t...
