Welcome to DISPLAYBLY.COM.
Today we are going to introduce an assemble process of COB LCD module for storage battery and it is big.
First, Visual inspection. Even though the LCD screens have been tested and passed the quality test, they still have to be checked again before the assembly.
Second, remove double-sided release paper and assemble the LED backlight into the PCB.
Third, turn on the LED backlight and check if there is any problem. Clean it if there is any dust.
Fourth, solder the PINs of the LED backlight onto the PCB with Tin.
Fifth, remove the protection film on the surface of the LED backlight and the protection film on back of the LCD screen. Install the LCD into the holes of the PCB.
Sixth, solder the PINs of the LCD onto the PCB with Tin.
Seventh, brush extra Tin with industrial alcohol.
Eighth, final testing. Check if there is any fault.
Last step is also visual inspection before packing. They are made in a dust-free workshop, but dust exists everywhere.
Thank you for watching and contact us if you have any questions.
