LED Dispensing

Put silver glue or insulating glue on the corresponding position of the LED bracket. For GaAs, SiC conductive substrates, red, yellow, and yellow-green chips with back electrodes, silver glue is used. For blue and green LED chips with sapphire insulating substrates, insulating glue is used to fix the chips.

The difficulty of the process lies in the control of the amount of glue. There are detailed technological requirements for the height of the colloid and the position of the glue. Since silver glue and insulating glue have strict requirements for storage and use, remind: the waking, mixing, and use time of silver glue are matters that must be paid attention to in the process.
