In order to achieve the effects of insulation, shockproof, sealing and dustproof, a layer of foam is also attached to the back of some electronic components. In the prior art, there are only single double-sided adhesive tape products and single foam products, so multiple attachments are required for the back of the electronic component. Multiple attachments will produce certain errors and introduce dust, causing product contamination, affecting overall performance, and reducing production efficiency. How to overcome the above technical problems has become the direction of efforts for technical personnel in this field. SUMMARY

[0004] To achieve the above purpose, the technical solution adopted by the present application is: a foam glue assembly for electronic component assembly, comprising a protective film, a micro-adhesive film, a bearing film, a double-sided adhesive tape unit and a foam product, the foam product is located between the upper surfaces of the protective film and the micro-adhesive film, the non-release surface of a release film is connected to the upper surface of the micro-adhesive film through a double-sided adhesive layer, and the double-sided adhesive tape unit is located between the release surface of the release film and the protective film.

[0005] The surface of the foam product in contact with the protective film has an adhesive layer, the bearing film is bonded to the lower surface of the micro-adhesive film, and the viscosity value of the micro-adhesive film upper surface and the foam product and double-sided adhesive layer is greater than the viscosity value of the micro-adhesive film lower surface and the bearing film.

[0006] The bearing film has a plurality of main positioning holes and first positioning holes, the micro-adhesive film has a plurality of second positioning holes, and the first positioning holes of the bearing film and the second positioning holes of the micro-adhesive film are matched.

[0008] The further improved solution in the above technical solution is as follows:

[0009] 1. In the above scheme, the upper and lower surfaces of the micro-adhesive membrane have a first micro-adhesive layer and a second micro-adhesive layer, respectively.

[0010] 2. In the above scheme, the viscosity value of the first micro-adhesive layer is greater than the viscosity value of the second micro-adhesive layer.

[0011] 3. In the above scheme, the release film is a blue release film.

The non-release surface 61 of a release film 6 is connected to the upper surface of the micro-adhesive film 2 through a double-sided adhesive layer 7. The double-sided adhesive unit 4 is located between the release surface 62 of the release film 6 and the protective film 1.

[0021] The surface of the foam unit 5 that contacts the protective film 1 has an adhesive layer 8. The carrier film 3 is bonded to the lower surface of the micro-adhesive film 2. The viscosity value between the upper surface of the micro-adhesive film 2 and the foam unit 5 and the double-sided adhesive layer 7 is greater than the viscosity value between the lower surface of the micro-adhesive film 2 and the carrier film 3.

[0022] The carrier membrane 3 has a plurality of main positioning holes 10 and a first positioning hole 11, and the micro-adhesive membrane 2 has a plurality of second positioning holes 12.

[0024] The thickness of the double-sided adhesive unit 4 is 0.2T.

[0025] The thickness of the release film 6 is 0.05T.

[0026] The aforementioned micro-adhesive membrane 2 and carrier membrane 3 are PC membranes.

[0027] Example 2: A foam adhesive assembly for assembling electronic components includes a protective film 1, 8 micro-adhesive films 2, a carrier film 3, 16 double-sided adhesive units 4, and 24 foam units 5. The foam units 5 are located between the upper surfaces of the protective film 1 and the micro-adhesive films 2. The non-release surface 61 of a release film 6 is connected to the upper surface of the micro-adhesive films 2 through a double-sided adhesive layer 7. The double-sided adhesive units 4 are located between the release surface 62 of the release film 6 and the protective film 1.

[0028] The surface of the foam unit 5 that contacts the protective film 1 has an adhesive layer 8. The carrier film 3 is bonded to the lower surface of the micro-adhesive film 2. The viscosity value between the upper surface of the micro-adhesive film 2 and the foam unit 5 and the double-sided adhesive layer 7 is greater than the viscosity value between the lower surface of the micro-adhesive film 2 and the carrier film 3.

[0029] The carrier membrane 3 has a plurality of main positioning holes 10 and a first positioning hole 11, and the micro-adhesive membrane 2 has a plurality of second positioning holes 12.
