Embodiment 1
[0042] Step 1, coating compound glue 6 on the substrate 3
[0043] First apply PMMA (Polymethylmethacrylate) glue, and then 9918 glue, of which PMMA (Polymethylmethacrylate) is about 1000 , because PMMA (Polymethylmethacrylate) is high temperature Glue can avoid the problems of glue cracking, denaturation, and dryness caused by high temperature in the whole production process. The use of this composite glue 6 successfully solves the wrinkling of the coating 7 ( Figure 19 ) problem, and played a very important role in the complete stripping of the coating 7, obviously, using the stripping effect of the composite glue 6 ( Figure 21 ) is better than using a single layer of glue 5 ( Figure 20 ) is much better. The thickness of the 9918 glue depends on the height of the arch of the air bridge 2. If the glue is relatively thick, it needs to be glued twice, and the hardening time should be prolonged appropriately.
[0044] Step 2. Bake at high temperature to make the edges and...
