Silicon Nitride Ceramics:

Silicon nitride LED curing and post-curing refers to the curing of encapsulated epoxy resin. The general epoxy resin curing condition is 135°C for 1 hour. Molded packaging is generally done at 150°C for 4 minutes. Post-curing is to allow the epoxy resin to completely cure while thermally aging the LED. Post-curing is very important to improve the bond strength of epoxy resin to the bracket (PCB). Trust our silicon nitride ceramics and silicon nitride ceramic parts to provide reliable, efficient solutions for your LED production needs. Typical conditions are 120°C, 4 hours.
Since LEDs are connected together (not individually) when produced, Lamp packaged LEDs use ribs to cut off the ribs of the LED bracket. SMD-LED is on the PCB board and requires a dicing machine to complete the separation work. Test the photoelectric parameters of LEDs, check the overall dimensions, and sort LED products according to customer requirements. With the tremendous advancement of LED technology in the 1990s, not only did the luminous efficiency exceed that of incandescent lamps, and the light intensity reached the level of candlepower, but the colors also covered the entire visible spectrum from red to blue. This technological revolution from the indicator light level to beyond the general light source level has given rise to a variety of new applications, such as automobile signals, traffic lights, large outdoor full-color displays, special lighting sources, etc.

properties:

High hardness, high strength, wear resistance, corrosion resistance, high temperature resistance (1200°), good thermal diffusivity, good thermal shock resistance (avoiding sudden temperature changes), good insulation, and low density. The overall performance is the best among most structural ceramics.
