Abstract
The utility model discloses a flexible printed circuit board coated with a metal film. The flexible printed circuit board comprises a circuit board base material and a coating film, wherein the coating film is a vacuum coating film; the vacuum coating film drops to contact the circuit board, so that slight pressure is formed, and the film can be well combined with the surface of the circuit board; and a metal shielding layer is sputtered on the surface of the coating film. The flexible printed circuit board coated has a rational structure; the vacuum coating film is arranged on the flexible printed circuit board, so that the coating film adhesion is increased greatly; the compact metal film has excellent electrical property and replaces the conventional silk-screen silver paste shielding layer, so that the thickness can be reduced, and the characteristics of the flexible printed circuit board can be better reflected; and furthermore, the flexible printed circuit board is simple in process, high in production efficiency and has high popularization value.
Description
Technical field
The utility model relates to a kind of circuit board, especially relates to a kind of flexible circuit board that covers metal film.
Background technology
Along with development of science and technology, the applying electronic product develops towards direction frivolous, multifunction gradually, especially along with development of Communication Technique.At present in flexible PCB (FPC) industry; The screen of a lot of products all is through starching at the outer silk-screen silver of flexible PCB (FPC); In case product is used for dynamic bending and bending radius when big, very high requirement has been proposed for the thickness of silver slurry and rich Qu Xingneng and silk-screen process.Under present condition, mostly this situation is to take to press two-layer flex circuit plate screen in the product outside, thus, certainly will improve cost, prolong Production Time, and the increase of thickness also is unfavorable for the rich Qu Xingneng of product.
Summary of the invention
The utility model purpose provides a kind of flexible circuit board that covers metal film.Make technical problems such as length consuming time, cost is high, plate body is thicker to solve the existing in prior technology circuit board.
For solving the problems of the technologies described above; The technical scheme that the utility model adopted is: a kind of flexible circuit board that covers metal film; Comprise board substrate and coverlay, said coverlay adopts vacuum overlay film, the sagging contact wiring board of this vacuum overlay film; Form light pressure, thereby film is better combined with the wiring board face; Said coverlay surface sputtering layer of metal screen.
The utility model is rational in infrastructure, through on flexible circuit board, adopting the vacuum overlay film, has improved the overlay film adhesion greatly; Fine and close metal film embodies good electric property, has substituted original silk-screen silver slurry screen; Can reduce thickness, more show the flexible circuit board characteristic, and technology be simple; Production efficiency is higher, the tool promotional value.
Description of drawings
Fig. 1 is the structural representation of the utility model.
Embodiment
Below through embodiment, and combine accompanying drawing, the technical scheme of the utility model is further specified.
Fig. 1 is the structural representation of the utility model.Can be known that by Fig. 1 a kind of flexible circuit board that covers metal film comprises board substrate 1 and coverlay 3, said coverlay 3 adopts the vacuum overlay film, and the sagging contact circuit plate of this vacuum overlay film forms light pressure, thereby film is better combined with the wiring board face; Said coverlay 3 surface sputtering layer of metal screens 2.
Through on flexible circuit board, adopting the vacuum overlay film, improved the overlay film adhesion greatly, fine and close metal film embodies good electric property, has substituted original silk-screen silver slurry screen, can reduce thickness, more shows the flexible circuit board characteristic.
