660nm can excite photosynthesis I and photosynthesis II, and promote the formation of chlorophyll B. For most plants, it is the most important wavelength. Someone calls it deep red, and someone calls it photo red. Now, we begin to talk about the 19 packaging processes of 660nm.
Because the chips provided by vendors are densely packed, in order to facilitate subsequent operations, we need to spread the chips.
Place chips after dispensing silver glue on the ceramic substrate.
Stick UV Film on the Bottom of the Ceramic Substrate
Remove UV Film
Taking Off LED
Test the radiant power, wavelength, and voltage. Divide them into different tubes according to BINs.
