Excellent solution for iPhone 6S home button not working

Customer sent an iPhone 6S to us, the fault phenomenon is that the iPhone home button is not sensitive and fail frequently. Get into IOS system to test it, the fingerprint function is normal. Sometimes the iPhone home button needs to be pressed several times before it can respond; we suspect there's a problem with the shrapnel button behind the fingerprint key.

Disassemble the iPhone by phone opening tools, then replace the fingerprint button and test it, now the home button function back to normal, so we exclude the iPhone motherboard error. Remove the waterproof adhesive covered by the shrapnel button, which is behind the fingerprint button. Put the multimeter on the corresponding pins, press the switch and test it, the data is normal, so we can eliminate the problem of the switch itself.

Put it under the phone repari microscope and observe it carefully, we found a rift in the edge of the line, pry the iron sheet off the power button, scrape the line, we can make sure it is disconnected. Solder the jump wire with phone rework station, this fault is resolved.

Before we pry the iron sheet, we need to clean up the solder tin in the red circle first by suction tin wire. If you don't clean it up, and directly pry it, it's easy to break the line again. Scrape the line with a sharp blade and gently scrape it, because the line is very thin, the blunt blade is easy to scrape off the line.

After the scrape, solder the tin on the pins. Find a thin copper wire and apply the tin, and then align them, heating the copper wire, finally you can fix it.

After soldering the jump wire, paint some green UV oil on it, fixed it with a UV lamp light, and then install the iron sheet in the same place. Welding the solder tin on the corner to fix it, and apply green UV oil to the edge position to fix the iron sheet.
