Embodiment Construction

[0010] In order to make the technical problems, technical solutions and beneficial effects solved by the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.

[0011] A recovery method for poor pressing of flexible printed circuit boards, which sequentially includes the steps of separation, flattening, ACF dissolution and cleaning:

[0012] The separation step is to separate the flexible printed circuit board and the glass substrate of the liquid crystal display by a peeling machine. Before the separation step starts, it is necessary to check the appearance of the flexible printed circuit board for the poorly pressed liquid crystal display module to confirm that there are no defects such as component defects or circuit breakage...

Abstract

The invention provides a method for recycling a poorly pressed flexible printed circuit (FPC). The method comprises the steps of separation, pressing, anisotropic conductive film (ACF) dissolution and cleaning treatment in sequence, wherein in the step of separation, the FPC and a glass substrate of a liquid crystal display (LCD) are separated by a stripper; in the step of pressing: the stripped FPC is put on the hot ironing board of the stripper again to be heated, connecting fingers of the FPC are pressed and ironed, and cured ACFs are heated and dissolved; in the step of ACF dissolution, the connecting fingers of the FPC are soaked in an ACF removing solution and then taken out to wait for dissolution of the ACFs on the connecting fingers of the FPC; and in the step of cleaning treatment, the connecting fingers of the FPC are wiped with a cleaning agent so as to clean the surfaces of the connecting fingers. The method provided by the invention has the beneficial effects of realizing effective recycle of the poorly pressed FPC, improving the material utilization and lowering the cost.

Description

technical field [0001] The invention belongs to the field of liquid crystal display manufacturing, and in particular relates to a method for recycling and processing a flexible printed circuit board when the liquid crystal display and the flexible printed circuit board are poorly pressed. Background technique [0002] Nowadays, new display technologies are in the ascendant, and liquid crystal displays (Liquid Crystal Display, LCD for short) have successfully replaced traditional cathode ray tube (Cathode Ray Tube, CRT for short) displays, and have become mainstream products in the market. LCDs are widely used in various electronic products such as mobile phones, computers, televisions, car DVDs, and global positioning systems (Global Positioning System, referred to as GPS). As a result, the output of LCD is getting higher and higher, there are more and more manufacturers, and the competition is becoming more and more fierce. Improving the utilization rate of materials is an ...
