[0039] Silicone protective film 3 is made of transparent S7512L-38, with polyester film PET as the base material. The polyester film PET has two layers. The polyester film PET is coated with a silicone glue layer, and the silicone glue layer faces away from the polyester film PET. One side is laminated with a layer of polyester film PET, the sum of the thickness of the two layers of polyester film PET is 0.076mm, the thickness of a single layer of polyester film PET is 0.038mm, and the thickness of the silicone glue layer is 0.01mm, 180° peeling machine The peel force of the test is 12.5g/25mm, the test standard is GB/T2792-1998, the sample test width is 25mm, the test object is SUS304 steel plate, the test speed is 300mm/min, the test conditions are: temperature 23±2℃, Relative humidity 65±5%. Several through holes of circular structure are opened on the silica gel protective film 3 .
[0040] The front release film 4 and the rear release film 5 are made of blue 100T055B respectively, the thickness of the front release film 4 and the rear release film 5 are respectively 0.1mm, and the residual adhesion rate tested by a 5000g range tensile machine is not less than 85% %, the peeling force tested by a 180°5000g range tensile machine is 25g/25mm. The front release film 4 is bonded to the grid release film 1 through the viscosity of MYLAR tape Ⅱ6 and the conductive double-sided adhesive 7, and the rear release film 5 is bonded to the grid through the viscosity of MYLAR tape Ⅱ6 and double-sided adhesive 8. grid release film 1. The left ends of the front release film 4 and the rear release film 5 respectively offer a step-structure avoidance port. Offer circular through holes on the front release film 4 .
[0041] MYLAR tape Ⅱ6 adopts black FTBFAP-15, including black polyester film, acrylic adhesive layer, and release layer arranged in sequence from top to bottom, with a total thickness of 15 μm, which has a good light-shielding effect and is peeled off by a 180° peeling machine test. The force is greater than 500g/25mm.
