Help needed for iPhone screen refurbishing (Dust problems)
We are currently practicing on refurbing iPhone screens (Glass repair only). We’ve tried almost everything, but we keep ending up with small dust particles under the glass.
Current equipment used at our store (Removing dust):
- Qianli iSee dust detection lamp
- Dust free clean cloths
- N-Hexane liquid to moist the cleaning cloth
- Dust free room with plexiglass on front
Also we use 8222 liquid to remove the old glue from old polarizer, and after that we use the N-Hexane.
Also, we use the 4 in 1 glass (OCA, Polarizer, Frame and glass premounted)
It takes us about 15 minutes if not more, just to get a 100% dust free result, and it’s killing us! A whole screen takes around 30 minutes, which is waaaay to long. 60-70% of the time used on refurbishing, are the process of eliminating dust on the LCD.
Priorly we used a humidifier to help cleaning out the dust, but a supplier told us that the mist could have small dust particles, so we stopped having the humidifier on, while doing the dust removing. We still have it on for around 10 minutes before doing the refurbing, as it should eliminate dust from the air inside the dust free room.
We’re running out of ideas, the only ideas coming to mind for now, is buying a compressor and air blower nozzle to eliminate the dust as much as possible on the screen, and then clean with cloth and n-hexane afterwards?
Really hope somebody can help out here, we are getting tired of re-doing LCD’s
Thanks in advance!
