Broke off small jumpers when prying battery out of iPhone.

There were apparently 3 extremely small black boxes that I broke off of the motherboard directly beside the sim card, which controlled my Home and Sleep/Wake buttons. Is there a way I can fix this myself? Should I bring it into a phone repair store? Would a phone repair store even work on this? I came here after seeing another thread that a guy had about the same issue, but it was never resolved and I could find no answers about if it's fixable or how they fixed it.

Here are 2 angles of where they belong on the board, with circles for each

and here are the 3 black boxes between some tape to keep them from flying away.

Edit: Thank you for fixing the images, oldturkey03!

I looked up the logic board layout, and found that the 3 components that broke off were called : Q3, U3, and DZ101_RF

Hi does anyone know where I could buy these chips?

DILeak, see attached image for the reference designators. The parts missing/broke are:

Reference Designator Q3 is RV1C001ZP DFN which is a Small Signal MOSFET datasheet is available here.

Reference Designator U3 is 74AUP2G34GN SOT1115 package is a Low-power dual buffer datasheet available here.

Reference Designator DZ101_RF is TPD4E101DPW SON4 and it is a ESD protection diode. That datasheet is available right here.

It will be no small chore to fix those. U3 is hard to come by (I am still waiting for a few from China since I can only find sellers offering minimum quantity of 1000).

Hope this helps, good luck

You said you're waiting on a few of these chips like the U3 from china, which means you're planning on re-attaching them yourself, right? How would one go about doing that? I've never soldered anything before, let alone something this tiny. I own a heat gun that goes from 200-900 degrees F and a large arm-mounted magnifying glass.

I did the same and now the iPhone had a really hard time removing the old battery now iphone reboots after a few minutes of use might have damaged the small black ribbon that's glued to the back the case under the top end of the battery. Tiny nick could this be the problem .

DPWCT--your problem is little bit different than this classic pry damage. If you've damaged the cable you described, you may lose function of the power/vol/mute or vibrate function.

If you're seeing random reboots it may be 1.) defective battery or 2.) a single tiny component knocked off near the battery connector---not behind the SIM tray. try a new battery and see if that solves.

I'm updating this answer--at this point (Summer 2014) I've repaired something like 50-100 phones with pry damage.

If you don't want to send out to have the repair done, then here are a couple of pieces of advice.

1.) About half of the time people underestimate the damage that is actually on the board--before you go order your parts, probe each tiny component with a small needle. Many times they are pushed up off their solder pads and will have to be replaced. An intact component will not move if probed with a needle.

2.) Even if you have your components that were pried off the board, 90% of the time they are damaged themselves. Especially the bottom two pads of U3---this one must have all 6 pads intact.

3.) If you have lost the bottom pad on Q3 or Q7 don't bother replacing it.

4.) The phone will work fine without DZ101_RF, however if you place this component incorrectly, you'll have a SIM recognition problem. I would advise leaving it off if you're just trying to fix your power + home button problem.

5.) If you accidentally tear off the pads on the motherboard at U3, it will be extremely difficult (but not impossible) to repair this defect. You'll have to make a custom microjumper.

6.) Try not to dislodge the adjacent R20 and R22 during your U3 repair--these are required and seriously small if you knock them off.

7.) Mis-placement of U3, or if it is dislodged but not completely gone, it will cause the phone to boot in recovery mode and fail to restore--this is another symptom of U3 pry damage. Your phone will not require restoring and will boot up as normal after you replace U3.

If you'd like more advice, feel free to contact me via my profile.

Jessa. What's your email address?

- de

my email address is jessabethany@gmail.com

PS: just re-read this thread and wanted to point out that if you use a heat gun hot enough to melt solder, you would melt the plastic parts of the SIM tray. You need a hot air gun with a tip to direct the heat exclusively at the component pads, plenty of flux, kapton tape to protect the SIM tray and 150 degrees of bottom heat from a preheater would help a lot.

Jessa, I think my iphone 5 is missing the component on the right side according to DILeak 's photos above. But I don't know what component it is. Can you tell me?

I think it has 5 solder pads. Like 4 make a square and there is one in the middle of all those. Maybe it grounds it to the substrate I don't know.

I have experience in electronic for 15 years but this is my first foray into trying to fix an iphone.

Thanks.

Since you've managed to keep the parts, just install them back. A heat gun should do the job. The only problem is to get the orientation right

Q3 is a 3 pin part, impossible to install backwards

U3 is a 6 pin part, the pin 1 faces 8 o'clock, the inscription faces right way up

the orientation of DZ101RF is not specified, but the inscription faces right way up

This is why I'm against prying the battery. puncturing the battery is dangerous, and you can easily scrape off tiny components. Avoid touching the battery. If you have to, just use the pull tab. If the tab breaks, remove all the expensive/delicate parts first, then pry the battery second

You say "Just install them back. A heat gun should do the job." But I don't understand what exactly you mean by that. If you could go into details about the steps to re-attach these, I'd be very grateful. I have never soldered anything before, let alone tried to reattach something this tiny. I do own a heat gun that goes from 200-900 degrees F and large arm-mounted magnifying glass, but no solder that small and I don't know where I would acquire some like that. I have contemplated using glue to reattach them, as well as soldering it using my focusable 1W laser mounted on a stand.

Thank you for the information!

This is really hard. I've never tried anything this small, you could probably ruin it further easily

I've repaired somewhere between 50 and 100 phones with this same pry damage. In my experience, probably about 90% of the times that someone still has the components, the components themselves are damaged from the prying and are not suitable for reattaching---you'd need to order new ones.

best advice would be that you ask your own question and post images of your phone as well. You can obviously not have the same issues if you have a different model :-) https://www.ifixit.com/Answers/Ask
