Description
Technical field
The utility model relates to graphite technology field more particularly to a kind of graphite flakes.
Background technique
Graphite flake is widely used in the fields such as mobile phone, but due to itself being also electric conductor, surface is easy to produce dust,
It is likely to cause circuit board short-circuit if dust is fallen on circuit board, it is therefore desirable to which graphite flake will be as far as possible in production
It is thin, meanwhile, consider the problems of thermal diffusivity, need the both sides bound edge of graphite flake few as far as possible, conventionally, as stone
The protective film selection of ink sheet is unreasonable, and bound edge setting is unreasonable, may cause and is unable to satisfy use demand.
Therefore, the prior art needs to improve.
Utility model content
The utility model embodiment the technical problem to be solved is that: a kind of graphite flake is provided, with solve in the prior art
There are the problem of.
According to the one aspect of the utility model embodiment, a kind of graphite flake is disclosed, comprising:
Silicone protective film, graphite flake, PET original film；
The silicone protective film fixes graphite flake, silicone protective film described in the Edge Distance of the graphite flake by double-sided adhesive
Distance be not less than 5 millimeters；
The PET original film is fixed on the edge of the graphite flake, and not covering the silicone protective film by double-sided adhesive
The part of coping stone ink sheet is completely covered；
The graphite flake is square structure, and four via holes are arranged on graphite flake, and a via hole, the mistake is arranged in each angle
The distance between hole is consistent；
The graphite flake upper surface covers included release film, and the shape of the included release film is consistent with the graphite flake.
In another embodiment based on the above-mentioned graphite flake of the utility model, the thickness of the graphite flake is not more than 1 millimeter.
In another embodiment based on the above-mentioned graphite flake of the utility model, the outside of the silicone protective film is arranged by one
Layer protective film, the appearance of the protective film are consistent with the appearance of the silicone protective film.
In another embodiment based on the above-mentioned graphite flake of the utility model, the width of the PET original film is 15-20 milli
Rice.
Compared with prior art, the utility model has the advantages that
The graphite flake of the utility model uses silicone protective film as substrate, and graphite flake is fixed on silica gel by double-sided adhesive
On protective film, it is fixed on the edge of graphite flake using PET original film, can preferably solve the problems, such as heat dissipation, conduction, this is practical new
Type structure is simple.
Detailed description of the invention
In order to illustrate the embodiment of the utility model or the technical proposal in the existing technology more clearly, below will be to embodiment
Or attached drawing used in description of the prior art does one and simply introduces, it should be apparent that, the accompanying drawings in the following description is this reality
