LED light emitting diode manufacturing process are as follows:, solid crystal = = "bake = =" welding line = = "sealing glue = =" bake = = "all = =" test = = "second cut = = = =" storage.
solid crystal link: the expansion of the crystal, the stent, thaw silver gel, etc..
sealing rubber parts: assembly mode, with glue - "vacuum, stent dip adhesive, mold filling glue, insert stent in the process can not be less.
above LED light emitting diode LED simple production process!

1.LED light-emitting diode production process:
LED LED production process a) cleaning: the use of ultrasonic cleaning PCB or LED stent, and drying.
LED light emitting diode production process B) rack: in the LED tube core (wafer) at the bottom of the electrode prepared on the Ag colloid expansion, will expand the tube core (wafer) placed on the thorn crystal, under a microscope with thorn crystal pen will Guan Xinyi a a installed on the PCB or LED bracket corresponding pads, followed by sintering the silver adhesive.
LED light emitting diode production process C) pressure welding: aluminum wire or wire welding machine will be connected to the electrode LED pipe, to make the current injection of the lead. LED directly installed on the PCB, the general use of aluminum wire welding machine. (gold wire welding machine are required for making white light TOP- LED)
LED light emitting diode production process d) package: by dispensing, with epoxy will LED tube core and wire protection. Glue on the PCB board, there are strict requirements on solidified colloid shape, which is directly related to the brightness of backlight source products. This process will also assume the task of point fluorescent powder (white LED).
LED light emitting diode production process E) welding: if the backlight is the use of SMD-LED or other packaged LED, then in the assembly process, the need to weld the PCB to the LED board.
LED light emitting diode production process f) cutting film: die cutting back light source required for a variety of diffusion film, reflective film, etc..
LED light emitting diode production process g) assembly: in accordance with the requirements of the drawings, the backlight source of a variety of materials to manually install the correct position.
LED light emitting diode production process h) test: check the back light source photoelectric parameters and the uniformity of the light is good.
LED light emitting diode production process I) packaging: the finished product in accordance with the requirements of packaging, warehousing.

LED light emitting diode in the final process shipment.
