Step 1: iPhone 6s got water broken. try to begin it up, the phone cannot boot normally.
Step 2: Take apart the phone and connect the phone with DC power supply, we have a tendency to square measure ready to see that the logic board comes with a serious current.
Step 3: dispose of the logic board. we have a tendency to square measure ready to see with naked eyes that the logic board is stale. Let’s run cleanup with PCB cleaner at the beginning.
Step 4: take away the defend sticker and remove the central process unit defend plate with a hot air gun.
Step 5: Since welded junctions of baseband defend plate go together with the high freezing point that cannot be removed by hot air gun merely. remove the baseband defend plate with cutting nipper.
Step 6: we'll see it clearly that areas beneath the defend plate are also water broken. throughout this case, brushes area unit helpless for entirely cleansing. therefore continue the cleansing technique with imperceptible cleaner.
Step 7: Pour adequate PCB cleaner into the imperceptible cleaner and place the logic board in. Power on and procure the lid on.
Step 8: 5 minutes later, shut down the power offer and do away with the logic board. After that, Leave to rest for five minutes.
Step 9: Check cleansing impact with naked eyes. Then raise scientific instrument yet again. The logic board looks nice once the imperceptible cleaner technique.
Step 10: Water injury, in addition, caused corrosion of rear camera instrumentation. therefore we've to change it with a current one. Apply some BGA paste flux and take down the broken instrumentation with a hot air gun. After that, clean with PCB cleaner and apply some BGA paste flux once more. Then solder the tins with a tool. Once finished, clean with PCB cleaner. yet again we've got a bent to use some BGA paste flux, align and install a current connexion so clean with PCB cleaner for impactive} impact.
Once rear camera instrumentation replacement finished, connect the phone with DC power supply and boot with startup signal triggered by a combine of tweezers. Booting current displays normally. Assemble the phone. Connect with the primary screen and power on, the phone goes with no show.
