This week we received a phone from a customer that had brought it from another shop only 2 months ago fully working and within this time the wifi had stopped working.
The iphone 6 plus was in good condition. We tested the device to find that the wifi switch was greyed out and they were unable to actually switch on the wifi on the phone.
This is a common issue on iphones and is either caused by a faulty wifi IC or a bad connection underneath the IC.
Luckily the iphone 6 series wifi ic is changeable unlike newer models and does not require any reprogramming, which makes it a relatively easy job for us. We preheat the board to 160 degrees so that we are able to scrape away the underfill surrounding the chip. Once this is done we are able to apply heat to the chip to reflow the solder underneath. We then tested the device and saw that the wifi function had been restored but we did not stop here. We know that once this fault has developed, if not repaired properly it can come back after time. So we reheated and removed the chip. We then cleaned the pads on both the motherboard and the wifi IC, reballed the chip and then reflowed it back into place on the board. This restores the connections much better than simply reflowing the IC. this is a tried and tested method by ourselves and we have found it to last long term rather than it being a short term quick fix.
