Embodiment Construction

[0022] The present invention will be described in further detail below through specific embodiments and in conjunction with the accompanying drawings.

[0023] Such as figure 1 with 2 As shown, what is described in the embodiment of the present invention is a method for making a capacitive touch screen FPC to prevent damage. In the production process of the group, the FPC used in the present invention is one of the components of the capacitive touch display screen, and the production has been completed, mainly in order to avoid the problem of breaking the FPC, which is a component of the capacitive touch display screen. The method includes the following steps:

[0024] Step 1. Make FPC. FPC finished products are produced through cutting, drilling, copper sinking, electroplating, film sticking, exposure, development and other processes. The production process of FPC finished products is produced by existing technical means.

[0025] Step 2. Attach the protective layer 2 with...

Abstract

The invention discloses an anti-broken manufacturing method of capacitance type touch display screen FPC (flexible printed circuit). The method incudes steps of step 1, manufacturing the FPC; step 2, bonding a protective layer with a hollow opening to a pin of a FPC welding pad, so that the hollow opening is faced to the FPC welding pad; step 3, crimping the FPC welding pad to perform FPC function test; step 4, binding the FPC to a touch display product; step 5, crimping the FPC welding pad pin to test the touch product; step 6, welding the FPC of the touch screen to the FPC of the display product; step 7, peeling off the protective layer from the FPC. The anti-broken manufacturing method has the beneficial effects of reducing the damage during the FPC welding process, improving the product yield, and reducing the product cost.

Description

technical field [0001] The invention relates to the field of FPC anti-bending, in particular to a method for manufacturing an FPC anti-bending of a capacitive touch screen. Background technique [0002] FPC is the most complex and versatile type of circuit board products, especially because it has the characteristics of light and thin, bendable, low voltage, low power consumption, etc., it can be three-dimensional with the size and shape of the internal space of electronic products. Wiring. Therefore, it is widely used in electronic products such as notebook computers, liquid crystal displays, hard disks, printers and automobiles. In the touch display screen, the FPC is the connection part between the screen and the IC, and is connected to the main screen by welding to play the role of data transmission. The FPC is a flexible material with a thickness of only about 0.1mm, and there are via holes on the soldering pins for the flow of solder, so the flexibility is relatively...
