In order to achieve the above purpose, the utility model adopts the technical scheme that: a high reliability assembly decal, comprising: the light stripping release film comprises a light stripping release film and a plurality of foam monomers positioned on the light stripping release film, wherein the foam monomers are arranged on the light stripping release film at intervals, each foam monomer comprises a heavy stripping release film and a foam body layer covering the edge of the lower surface of the heavy stripping release film, the central area of the foam body layer is a hollow area, and the upper surface and the lower surface of the foam body layer are both coated with adhesive layers;

heavy peel off from the type membrane and light peel off from the type membrane and pass through the bonding of bubble cotton body layer, heavy peel off from type membrane one end has one and draws the ear, and this draws the ear and heavily peels off from the type membrane junction and has a score line, draw the ear to turn over to the outside along the score line.

The further improved scheme in the technical scheme is as follows:

1. in the scheme, the heavy-peeling release film of the foam monomer is a PET fluoroplastic release film, a PET silicone-containing release film, a PET matte release film or a PE release film layer.

2. In the above scheme, the light-stripping release film is an organic silicon release film or a non-silicon release film.

3. In the scheme, the foam single body is rectangular.

4. In the scheme, the thickness of the heavy peeling release film is 50-150 mu m.

Because of above-mentioned technical scheme's application, compared with the prior art, the utility model have the following advantage:

the utility model discloses high reliability equipment pad pasting, its a plurality of bubble cotton monomer sets up on light peeling off from the type membrane with interval, bubble cotton monomer is by heavy peeling off from the type membrane and cover in the bubble cotton body layer of heavy peeling off from type membrane lower surface edge, and this bubble cotton body layer's central zone is the fretwork district, bubble cotton body layer upper surface, lower surface all coat and have the gluing layer, and heavy peeling off from the type membrane and light peeling off from the type membrane through bubble cotton body layer bonding, both avoided bubble cotton monomer size less, lead to a large amount of bubble cotton monomers to be difficult to deposit and shift, also avoided the bubble cotton monomer at the transfer or use easy drop's not enough to conveniently shift and use; in addition, it lies in heavily peeling off from type membrane on the type membrane and has one to draw the ear, and this draws the ear and heavily peels off from type membrane junction and has a score line, draw the ear to turn over to the outside along the score line, the person of facilitating the use gets puts the cotton monomer of bubble to work efficiency has been improved.
