What is this component that is broken off iPhone 6 logic board?

Hi everyone, first post here,

Firstly I sent my iphone off to a shop that does iphone glass repairs, when i got my phone back the touch ID didnt work, i have tested everything from changing all connectors including backplate and screen, and I am sure that this is finally my problem.

I got out my macro lens and zoomed in and compared it against another iPhone 6 logic board and noticed that these small components had been broken off the logic board

Pictured below

I was just wondering what these components could be, if you also compare it against the iFixit pictures you can see that these are present in their pictures, and if anyone knows these components where could i get them from? Thanks.

Answer this question I have this problem too

Is this a good question?

it looks like the pads are gone so you wont be able to replace it. you will probably have to make a jumper for it. if your not able to do that level of repair then it might be best to send it off for repair.

if you are going to try the repair yourself the best to purchase the zxw dongle. its a great tool. check it out on youtube

That is supposed to be a 2.2 micro farad capacitor to absorb a certain frequency providing slightly better performance, so it probably is not your problem. Also that capacitor doesn't appear to be related to the touch sensor. The touch sensor won't work if the home button was replaced. You may want to ask the shop if the home button was replaced with the glass.

Hi thanks for your answers, I know that you can't replace the sensor and I did ask and he was certain he had not replaced them, i have tested everything and this is the only thing I can see to be damaged, all the flex cables are in tact and have tested everything, I'm not sure what to do.


Well, you can get the components from and I realized there is also a cap of the same value that is twisted a little lower in the picture. Also the pads may just be very corroded. If you can work under your macro lens, you can try lightly scraping the pads with a needle to see if they clean up. But you may not be able to replace something that small without a micro soldering pencil and a microscope. If you want to spend $800 to $1500 to set yourself up with that stuff, I can give you links to the things you would need. Also, could there be long screw damage? You can also try the suggestions in this thread. Touch ID not working after screen replacement?
