What are the processes for LED production?
Pressure welding: the electrode is connected to the LED core by aluminum wire or wire bonder, which is used as the lead for the current injection. LED installed directly on the PCB, the general use of aluminum wire welding machine. (making white TOP-LED requires wire welding machine)
A: the LED tube core (wafer) bottom electrode prepared on silver colloid after expansion, will expand after the tube core (wafer) placed in the thorn crystal on the stage, will die a pad installed in the PCB or LED support corresponding with thorn crystal pen under the microscope, then the sintered silver glue curing.
Cleaning: use ultrasonic cleaning PCB or LED bracket, and drying.
