Solution:
1. The heat dissipation of the LED display must be done. We must consider the heat dissipation of the LED display during engineering design. Yinhan Zhixian fully considers that the poor heat dissipation will cause the color difference of the LED display from the design point. problem.
2. First prepare the phosphor powder cake, and then paste the cake on the surface of the chip through the paste method to achieve LED packaging
3. When buying phosphors, we must choose famous brands, and we must make samples many times before making goods in batches.
4. AB glue solidifies and releases at 120-130 degrees/30-40 minutes. If it exceeds 150 degrees or it is baked for a long time, it will turn yellow.
