. First: the broken line is point D, then in production we can directly test the tension and thrust of the line arc. If these two conditions are met, it may not be a problem with the wire bond. Second: Of course, the expansion coefficient and internal stress of silica gel will also affect, you can do it yourself. Third: it is the airtightness of the bracket, which is very important. After we finished the red ink in the 5730 lamp beads, the red ink directly penetrated from the bottom of the bracket directly into the inside of the bracket (not from the joint of silica gel and PPA). If this is the case, the D point is broken. It must be the reason for the bracket (because of the stamping). If the airtightness of the bracket is not good, the bracket will loosen under special circumstances (such as bending test, etc.). Our silica gel and the entire stent will stick together after baking. When you bend the light bar, the stent will be slightly deformed or loosened, and then the silicone will peel off from the stent. At this time, it is definitely the D point of the positive or negative electrode. The above is a personal opinion and is for reference only.
