LED Spotlight Production Process

1. Cleaning: Use ultrasonic cleaning to clean the PCB or LED bracket and dry it.
2. Mounting: After preparing silver glue on the bottom electrode of the LED core (large wafer), expand it, place the expanded core (large wafer) on the crystal table, and use a crystal pen to install the cores one by one on the corresponding pads of the PCB or LED bracket under a microscope, and then sinter to solidify the silver glue.
3. Pressure welding: Use aluminum wire or gold wire welding machine to connect the electrode to the LED core as a lead for current injection. If the LED is directly mounted on the PCB, an aluminum wire welding machine is generally used.
4. Packaging: Through dispensing, the LED core and welding wire are protected with epoxy. Dispensing glue on the PCB board has strict requirements on the shape of the colloid after curing, which is directly related to the brightness of the finished backlight source. This process will also undertake the task of dotting phosphor (white light LED).
5. Welding: If the backlight source uses SMD-LED or other packaged LEDs, the LED needs to be soldered to the PCB board before the assembly process.
6. Film cutting: Use a punch to die-cut various diffusion films, reflective films, etc. required for the backlight source.
7. Assembly: According to the requirements of the drawing, manually install various materials of the backlight source in the correct position.
8. Testing: Check whether the photoelectric parameters and light uniformity of the backlight source are good.
9. Packaging: Pack and store the finished products as required.
