Abstract

The invention discloses full-page type FPC double-sided adhesive tape. The structure of the adhesive tape is matched with the full-page type FPC structure. The adhesive tape comprises a black side protection film, adhesive bodies and a white side protection film, wherein the adhesive bodies are arranged between the black side protection film and the white side protection film, the number of the adhesive bodies and the number of FPCs in a full-page type FPC are matched and correspond one to one, and the release force of the black side protection film is smaller than that of the white side protection film. The FPC double-sided adhesive tape is of a full-page type structure, and the adhesive bodies between the white side protection film and the black side protection film and the FPCs in the full-page type FPC correspond one to one, so the adhesion of the double-sided adhesive tape on the FPCs is facilitated, and the one-by-one adhesion mode in the prior art is replaced; the release forceof the black side protection film is smaller than that of the white side protection film, so the adhesive bodies cannot be taken away when the black side protection film is torn off during adhesion.

Description

technical field [0001] The invention relates to the technical field of backlight manufacturing, in particular to a full-page FPC double-sided adhesive tape and a method for using the same. Background technique [0002] In the process of backlight assembly, it is an important process to attach FPC double-sided tape to the full-page FPC (Flexible Printed Circuit, flexible circuit board). Operators have high requirements for operating skills, and they are prone to defects such as sticking deviation and blocking the LED light outlet, resulting in dark areas and light beams in backlight products. It takes more than two months to train a new employee to skilled operation. This leads to low production efficiency and high scrap rate, which increases production cost and production time. Contents of the invention [0003] In view of the above-mentioned problems existing in the prior art, the purpose is to provide a full-page FPC double-sided adhesive tape that is convenient for at...
