Abstract
The utility model discloses a kind of mould release membrance, including the antistatic backing set gradually from bottom to top, dope layer, supporting layer and release layer, the outside of the release layer are provided with a plurality of linear recess structures.Further, the traditional thread binding groove structure is ripple groove or linear groove.Mould release membrance of the present utility model in release layer surface by setting linear recess structure, reduce the adhesion between mould release membrance and graphite radiating film, during by graphite radiating film and release UF membrane, reduce the possibility that both are damaged, by setting fluorescence round dot dope layer, it is convenient to judge whether graphite radiating film surface remains mould release membrance, ensure that mould release membrance can thoroughly remove from the surface of graphite radiating film.
Description
Technical field
It the utility model is related to membrane material, and in particular to a kind of mould release membrance.
Background technology
In electronics industry, the integrated circuit in mobile phone, tablet personal computer produces substantial amounts of heat in the case of working long hours,
Need to paste graphite radiating film by heat derives in circuit board surface, graphite radiating film is that a kind of have high heat conduction into film-form
The Heat Conduction Material of rate, it can be by heat transfer caused by circuit board to radiator, and the heat be advantageous on circuit board is rapid
Spread so as to reduce the temperature of electronic unit.
Graphite radiating film is formed by graphite flake compacting, and graphite radiating film easily overlaps and led in pressing process
Cause graphite film surface fold occur, when fitting is with circuit board surface, easily occurs gap between circuit board or fall off,
Heat dispersion is influenceed, existing solution is usually in one layer of mould release membrance of graphite radiating film surface mount, pressure in pressing process
After the completion of system, then mould release membrance opened.
In the pressing process of graphite radiating film, the gap between graphite radiating film and mould release membrance reduces, between the two
Adhesion increases, and easily causes when opening mould release membrance, and graphite radiating film is damaged with mould release membrance or mould release membrance removes not
Thoroughly, the surface of graphite radiating film is adhered to, influences the heat dispersion of graphite radiating film.
Utility model content
The purpose of this utility model is to provide a kind of mould release membrance, it can solve in the prior art graphite radiating film with it is release
Adhesion between film is big and mould release membrance removes halfway problem.
In order to solve the above problems, the utility model uses following technical scheme：
A kind of mould release membrance, it is characterised in that including the antistatic backing set gradually from bottom to top, dope layer, supporting layer and
Release layer, the outside of the release layer are provided with a plurality of linear recess structures.Further, the linear recess structure is ripple
Shape groove or linear groove.
Further, the dope layer is provided with a plurality of fluorescence round dots, the area of the fluorescence round dot and supporting layer
Area ratio is 1:200-1:500.
Further, the number of the upper fluorescence round dot of every square metre of dope layer is 25-75.
Further, the supporting layer is PET supporting layer, and the thickness of supporting layer is 25-55 μm.
Further, the release layer is silicone oil release layer, 15-25 μm of the thickness of release layer.
Further, the antistatic backing is nano anti-static layer, and the thickness of antistatic backing is 5-10 μm.
Further, the depth of the linear recess and the thickness ratio of release layer are 1:15-1:20.
Compared with prior art, the beneficial effect that the utility model is realized：Mould release membrance of the present utility model passes through release
Layer surface set linear recess structure, reduce the adhesion between mould release membrance and graphite radiating film, by graphite radiating film with
During release UF membrane, the possibility that both are damaged is reduced, it is convenient to judge by setting fluorescence round dot dope layer
Whether graphite radiating film surface remains mould release membrance, ensures that mould release membrance can thoroughly remove from the surface of graphite radiating film.
