Technical Field

The invention relates to the technical field of COF substrate processing, in particular to a multifunctional manual perforating machine suitable for perforating a COF substrate.

Background

With the continuous development of science and technology, electronic products are developing towards miniaturization, intellectualization, high performance and high reliability, a packaging substrate is transited by an FPC (flexible printed circuit) like a COF (chip on film), the PTCH value of the COF substrate is smaller and smaller, pins in the packaging are also more and more dense and precise, and the integrated circuit packaging not only directly influences the performance of an integrated circuit, an electronic module and even a whole machine, but also restricts the miniaturization, low cost and reliability of the whole electronic system. Under the conditions of the gradual reduction of the size of the integrated circuit wafer and the continuous improvement of the integration level, the electronic industry puts higher and higher requirements on the integrated circuit packaging technology.

The existing COF production carries out scrapping treatment on defective products, mainly carries out blackening treatment on a COF key part (alignment MARK) or punctures the COF key part (alignment MARK) by a sharp pencil sharpener, and the mode has the following defects:

1. the COF key part (alignment MARK) is blackened, so that the COF substrate is polluted, and when the illumination of the CCD is enhanced, the alignment MARK at the blackened position is identified again, so that a defective product is used, the cost is wasted, and the production efficiency is reduced.

2. The puncture treatment of the key position (alignment MARK) of the COF causes the product to break due to uneven tension during the roll-to-roll transmission process.
