Remove the adhesive tape and peel off the liner, then stick it onto the painted test board. use6.8 kgThe roller rolls twice in the same direction.

All test panels (short-term) 90 Except for peeling, pulling, and bending panel tests, after bonding the tape to the painted test panel with aluminum and before starting exposure, follow the instructionsGMW3221, codeAconduct 72 Hour adjustment, and1 hAfter exposure, before testing.

90 Degree peeling test. Unless otherwise specified, the sample should be exposed to environmental conditions before the peel test 1 Adjust after hours. 90 Degree peeling test should be used3.4.1.7.1to3.4.1.7.4The program in progress.

Insert the fixture for fixing the test board into the lower jaw of the stretching machine. The fixture must be able to maintain during the testing period 90 Degree stripping.

Assembly size requirements:

Flatness of the bottom surface of the character plate assembly0.5，

Bottom tape and letter circumferential gap0.25+0/-0.25、0.5±0.5

Part size requirements:1The shape of the double-sided tape is offset by the outline of the letters0.5/0.25The thickness is specified by the customer;

2The shape of release paper is larger than that of double-sided tape on one side3-5mm，t=0.2mm；

3The size of the cardboard frame is larger on one side than the shape of the signboard15mm，t=2mm；

4The size of the protective film is smaller than one side of the cardboard frame3-5mm，t=0.1mm；

For double-sided tape: must meetGMW15201 Type IA or VIATape thickness:0.76mm.

For release paper: It should be white or have a significant color difference from the tape. thickness is0.1mm. Before it is torn off, there should be no breakage. There should be no wrinkles around the release paper, and the nameplate and protective film should not peel off when it is torn off. The release paper should be large enough to facilitate the operation of the final assembly workers.

For protective film: it needs to meetGM3807M type IIBrequirement. The adhesion of the protective film cannot change within one year at room temperature; At the same time, the protective film cannot be peeled off during the process of removing the character release paper. The protective film should be the same size as the paper frame and at least larger than the size of the nameplate15mmThe supplier must press the contact surface between the protective film and the paper frame to ensure the adhesion between the protective film and the paper frame.
