Background

The manufacturing process of the chip can be roughly divided into a wafer processing process, a wafer probing process, a packaging process, a testing process and the like. The wafer processing step and the wafer probing step are front-end steps, and the packaging step and the testing step are back-end steps. The main task of the wafer processing is to fabricate circuits and electronic devices (such as transistors, capacitors, logic switches, etc.) on the wafer. The wafer probing process is to cut the wafer into individual dies, test the electrical characteristics of each die by a probing instrument, sort the dies according to the electrical characteristics, load the dies into different trays, and discard unqualified dies. The packaging process is to fix the single crystal grain on the chip base made of plastic or ceramic, connect some lead terminals etched on the crystal grain with the pins extended from the bottom of the base for connecting with the external circuit board, finally cover the plastic cover plate and seal it with glue, so as to protect the crystal grain from mechanical scratch or high temperature damage. The testing procedure is the last procedure of chip manufacturing, and is to place the packaged chip in various environments to test the electrical characteristics of the chip, and divide the chip into different grades according to the electrical characteristics of the chip; or according to the technical parameters of special requirements of customers, taking out part of the chips from similar parameter specifications and varieties to carry out targeted special tests.

The existing products are closely arranged into a rectangular packaging plate after a packaging process, and in order to protect the internal products, a layer of plastic film is arranged on the outer side of the packaging plate, so that the plastic film needs to be torn off from the products in order to facilitate subsequent processing. The method adopted by the prior art is purely manual operation, and because the film is tightly combined with the outer surface of the product, the film is often torn unclean and remains on the lead frame in the tearing process, so that the lead frame is deformed, plastic package is damaged, and the product is damaged, and therefore a high-efficiency reasonable device is urgently needed to solve the problem.

In view of the above, we propose a simple film tearing device for a chip carrier tape to solve the above problems.
