A processing tool for a composite flexible circuit board for a capacitive touch screen

Abstract

The invention relates to the technical field of flexible circuit board lamination, in particular to a composite flexible circuit board for a capacitive touch screen, comprising a base frame, a positioning structure is installed on the base frame, and the base frame is connected to a position-limiting structure, so that the The bottom frame is provided with a push structure, an adjustment structure is installed on the push structure, an auxiliary structure is connected to the adjustment structure, and a heat release structure is installed on the auxiliary structure. Let the protective film be heated evenly, so that the protective film can better adhere to the plate, prevent the protective film from warping and opening, and make the laminated plate better enter the next process.

Description

technical field [0001] The invention relates to the technical field of lamination of flexible circuit boards, in particular to a processing tool for a composite flexible circuit board for a capacitive touch screen. Background technique [0002] Flexible circuit board is a kind of highly reliable and excellent flexible printed circuit board made of polyimide or polyester film as the base material. It has high wiring density, light weight, thin thickness, bending Therefore, many circuits behind capacitive touch screens use this composite flexible circuit board to connect with other components, so that it will be more convenient for maintenance personnel to repair and replace other components, and use flexible circuit boards It can also avoid the problem of wire arrangement. [0003] However, in the process of flexible circuit board production, it is necessary to cover the copper foil circuit with a protective film to avoid circuit oxidation or short circuit, and at the same t...

Problems solved by technology

[0003] However, in the process of flexible circuit board production, it is necessary to cover the copper foil circuit with a protective film to avoid circuit oxidation or short circuit, and at the same time play a role in insulation and product bending. In the process of laminating the protective film and copper foil circuit The operator needs to wear dust-proof gloves to fit it by himself, but the long-term work will lead to an increase in the error rate of the operator, and due to the negligence of the operator, when it is further heated and fitted, As a result, some parts of the protective film are heated unevenly and are easy to open and warp
