In this video I demonstrate how to repair your iPhone wifi with a heat gun. It is an alternate method to reflow (rehot, rework) your fatigued solder joints connecting the wifi chip and components to the printed circuit board (pcb), aka motherboard. The original article and additional feedback on using the heat gun method can be found at Reflowing the iPhone motherboard using an oven is a proven method to repair the iPhone wifi. Here is a list of successes using the oven method: Advantages of the Heat Gun method over the Oven method: 1) Concentrated application of heat only on the problem wifi components. 2) Shorter treatment time. 3) Ability to use lead-free solder to gauge treatment period. Despite the fact that the oven method works, it carries the risk of damaging your entire motherboard because oven temperatures can be difficult to control. On the other hand, a heat gun will allow you to concentrate the heat on the location of the wifi chip connections without applying heat to the other board components. This method will work with the iPhone 2G, 3G, 3GS. In fact, it will work with the iPhone 4 when those phones accumulate solder fatigue over time and begin to fail. The 2G is a little more difficult to rework than the 3G and 3GS because the motherboard is connected with solder rather than a push-in connector. In addition, this method will also repair the iPod Touch or any other unit that fails due to fatigued solder joints

    Worked great on my iPad. I just used my hot air gun and blew at about 250C for 20-30 seconds on the little can next to the antenna connections. This can was on the same strip as the I/O cable.

    you say this works with an ipod touch. is there anyway you can show us exactly how to do this with an ipod touch? I am not quite clear on if I need to tear down the whole itouch or if I can focus the heat on the back of the itouch what? I have tried the chill fix and nothing happened.

    Hi my friend,
    I been watching this your video, and all look seemed to clarify,
    I have started to do it by my self, I bought all components to begin this work, but there left only one thing/tool which I still cant find where actually to buy, this one which you used to cover motherboard, it’s made from silicone, in blue color, how it’s called?
    so please be kind and let me know the name, place where I can buy this tool.
    Thanks, any suggestions would be much appreciated.

  • originaldanman says:

    P.S. I did the BT – WF module at the same time. I couldn’t see where it would hurt, I figured that if I didn’t and it didn’t work I’d have to take it apart again and do it anyway, so might as well kill 2 birds with one stone.

  • originaldanman says:

    Just fixed wifi after not working for almost a year. Works great! The only difficult part is taking it apart and putting it back together. It took me about 45 minutes start to finish.  Thanks much!!

    Dear all,
    my 3g wifi works only during the winter. in the summer is “on holiday”. I mean it works only below 25° C. Should I do this treatment to repair it?
