Description

FPC tectorial membrane is shelled membrane mechanism in advance and FPC tectorial membrane dyestripping machine

Technical Field

Background

Flexible circuit boards, also known as flexible circuit boards, are favored because of their excellent characteristics of light weight, thin thickness, free bending and folding, etc. Along with the rapid development of the electronic industry, the design of circuit boards tends to be high-precision and high-density, and the development of FPC industry becomes a necessary trend. In the FPC flexible circuit board industry, a layer of FPC protection film needs to be covered on FPC, and the main functions of the protection film are as follows: 1. the copper foil is protected from being exposed in the air, and the oxidation of the copper foil is avoided; 2. covering for subsequent surface treatment; 3. in the subsequent SMT, a solder resist function is achieved.

During transportation and protection of the FPC protective film, a layer of base paper is covered on the film, and the base paper needs to be separated before the protective film is used. The existing equipment essentially peels the film from a roll of web material, cuts it into individual sheets, and then applies it to the copper foil. The scale of most fpc factories in China is smaller, the number of single products produced every day is smaller (tens to hundreds of single products), and cost waste is caused by film rolling, so that the factories preferably use single and punched protective films, and the protective films are manually torn and then attached to copper foil. The existing equipment rarely has automatic single protective film feeding, film tearing and film pasting, but the problems of low labor efficiency and high production cost exist when the automatic single protective film feeding, film tearing and film pasting are manually completed, and the existing problems are solved by urgently researching the equipment capable of completing the single protective film feeding, film tearing and film pasting. Meanwhile, the film material is difficult to lift and cannot lift (namely, one side of the film material is separated from the FPC covering film) in the mechanical film tearing process, so that the film tearing failure is caused, the film material is required to be repeatedly torn for a plurality of times, and the production efficiency is low, and therefore, the problem of film tearing and lifting is also required to be solved.
