Embodiment Construction

[0010] The present invention is described in further detail below in conjunction with embodiment.

[0011] A reworking process of a liquid crystal module, the steps are: a), using a silica gel removal solution mixed with a modified fluororesin, a polar or non-polar organic solvent, and a surfactant to remove the protective silica gel of the module; b), using The stripping solution mixed with fatty acid ethylene oxide adduct, electrolyte and surfactant separates the LCD screen from the IC; c), removes the IC with a removal solution mixed with polar organic solvents, surfactants and preservatives residual.

[0012] Wherein, the number of parts of each component of the silica gel removal solution is: 40-70 parts of modified fluororesin, 30-50 parts of polar or non-polar organic solvent, 1-5 parts of surfactant, and 0.05-50 parts of other organic impurities. 3.0 servings.

[0013] Wherein, the parts of each component of the stripping liquid are: 10-40 parts of fatty acid ethylen...

Abstract

The invention discloses a reworking process of a liquid crystal module. The reworking process includes the following steps: a) protective silica gel of the module is removed by silica gel removing liquid which is formed by the mixing of modified fluororesin, a polar or non-polar organic solvent and a surface active agent; b) a liquid crystal screen and an IC are separated by stripping liquid which is formed by the mixing of a fatty acid ethylene oxide affixture, an electrolyte and a surfactant; c) the residual IC is removed by the removing liquid which is formed by the mixing of the polar organic solvent, the surface active agent and an antiseptic agent. By adopting the chemical principle to carry out reworking, the reworking process in the invention can effectively recycle defective products at low cost, so as to save resources, thereby greatly increasing production benefits for enterprises; moreover, reasons that the module is defective can be effective analyzed.

Description

technical field [0001] The invention relates to a rework process for defective products of a complete set of liquid crystal modules. Background technique [0002] At present, there are two ways to deal with defective liquid crystal modules (especially COG modules): one way is to directly count them as waste products; the other way is to use mechanical means to rework (rework), and the obtained ICs are digested with nitric acid for utilization. [0003] These two treatment methods all have disadvantages: the former causes material waste, and the latter needs to invest in special equipment, and has extremely low efficiency and high risk, and the effect is often not as good as the first method. Contents of the invention [0004] The purpose of the present invention is to provide a process for reworking defective liquid crystal module products using chemical principles. [0005] The technical solution adopted by the present invention to solve the technical problem is: a liqui...
