Welcome to DISPLAYBLY.COM.
Today we are going to introduce an assembly process of edge LED backlight for massage chair.
First, put the dedicated stainless steel mold onto the surface of the PCB and make the TIN evenly cover on it.
Second, put the PCB into the LED soldering machine and the LEDs will be automatically soldered onto the surface of the PCB by the machine.
Third, let the PCB pass through the reflow soldering machine to make LEDs fixed on the PCB.
Fourth, put the PCB into the dedicated mold and the PINs will be automatically installed into the holes of the PCB by the machine.
Fifth, press the heads of PINs with the pressing machine and glue them.
Sixth, put the light guide plates onto the production line. The reflection sheet will be automatically put onto the back, the light-blocking film will be automatically wrapped around the edge and the diffusion sheet will be automatically put onto the surface.
Seventh, install the PCB into the light guide plate by hand.
Eighth, quality test. Check if there is any fault.
Thank you for watching and contact us if you have any questions.
