Problems solved by technology

[0004] However, in the above degumming process, since the heat gun can only locally heat the ACF, and the softened ACF still has a certain adhesive force, it is easy to damage the substrate or the pin part of the circuit board when scraping off with a scraper. Damage is formed, and the entire LCD module is scrapped, resulting in a waste of industrial costs

Embodiment Construction

[0014] The present invention will be described in detail below in combination with specific embodiments. Please refer to figure 2 , figure 2 It is a structure diagram of the liquid crystal module of the present invention, wherein the liquid crystal module 21 includes a substrate 211 , a flexible circuit board (Flexible Printed Circuit; FPC) 212 and an ACF glue 213 for bonding the substrate 211 and the FPC 212 . During operation, the FPC212 needs to be folded up along the dotted line to expose the ACF glue 213 .

[0015] image 3 is a schematic diagram of a first embodiment of coating an ACF dissolving agent according to the present invention. Such as image 3 Shown, one end of cotton swab or dust-free cloth 22 is stuck with ACF dissolving agent, and its main component is alcohol, formic acid and tensio-active agent. Apply the dissolving agent to the ACF glue 213 to make it react and dissolve. Then use scraper 23 to scrape off the dissolved ACF glue, as Figure 4 shown...

Abstract

The invention relates to a removal method of an anisotropic conductive adhesive of a liquid crystal display, which at least comprises the followings steps: coating an anisotropic conductive adhesive solvent at a pressing area of two elements, so that the anisotropic conductive adhesive solvent is permeated into the anisotropic conductive adhesive so as to dissolve the anisotropic conductive adhesive and form a dissolving area; tearing the dissolving area so as to allow the dissolved anisotropic conductive adhesive to be exposed; scraping and removing the dissolved anisotropic conductive adhesive with a scraper, and allowing the undissolved anisotropic conductive adhesive to be exposed; and repeating the steps until the two elements are fully separated.

Description

technical field [0001] The invention relates to a method for removing the anisotropic conductive adhesive of a liquid crystal display, in particular, the invention relates to a method for removing the anisotropic conductive adhesive of a liquid crystal display using a dissolving agent. Background technique [0002] With the rapid development of electronic products towards lightness, thinness, shortness and miniaturization, liquid crystal displays (Liquid Crystal Display; LCD) are used as display panels in almost all kinds of portable electronic products, especially in video recorders, notebook computers, etc. , mobile phones or personal digital processors and other products, liquid crystal displays have become an important component. In addition to the LCD panel, the liquid crystal display must be connected with a driver chip on its periphery for the purpose of controlling the display signal. Generally speaking, the interface connection technology between the LCD panel and ...
