Soldering point for iPod touch 2nd generation battery

I have a similar problem posted previously in this forum that one of the three soldering points for the iPod touch battery was lifted off the board in the effort to replace the old battery. In this case, it was the middle one which is depicted in the image (click link below) I got from the instructions here to replace the battery. I was wondering if I could jumper the middle portion of the battery flex cable (not shown in the pic but imagine it's there lined up on the three soldering points) to the ciruit test point shown by the head of the red arrow and/or the point indicated on the X to get the continuity required by that middle connection to re-charge the battery. It's been a while since I read circuit board schematics so I appreciate anyone's help. BTW, I was trying to insert the picture in here but it wouldn't let me, so I uploaded it to Webshots to host, hopefully you can see it ok...thanks.

Paul,

These boards are heat sensitive and fragile. I had the exact same issue on the first one I worked on. I solved it by simply sliding the entire battery ribbon terminal down far enough to just touch the pins you show on the drawing and also still make contact to the 2 pads that did not de-laminate from the board. I had luck with that repair and you should too. Please let us know how you do!

I was able to solder it to the nearest middle contact as show on the picture. I accidentally spilled solder onto the other contact marked with an X on the picture in the link and it didn't work properly until I took it off. It did work after that, very happy now its charging, but I have another problem in that the touchpad is not working, despite getting a replacement digitizer screen. I wonder if I have to have all the screws on the touch screen frame, as well in other areas, screwed in first before the touch screen works.

No that wouldn't affect the digitizer/touch. It must not be completely plugged in. They tend to come unplugged easily if you aren't careful. Try gently aligning it and pushing it until it snaps a couple times one at each end. You should however replace the screws! Make sure you also put a small pc. of tape over the battery terminals so they don't short out.

Here's a photo of the pads and test points:

Hi all i m Wites who remake iphone 2g,3g,3gs and 4 with pcb layout and easy search of components if you need download from this forum http://forum.gsmhosting.com/vbb/f631/

Carpenter that is not really like you draw 5V it have 3.7V from battery coming the middle is NTC batt temp pin.

I know this is old, but I lifted the power pad on the right... the case was already open when the pod started getting really hot on the back. I grabbed the battery ribbon cable in hopes that the thin flex would break and I could just get a new battery.Well i lifted the pad... all of it. Where could I tack a wire to get the +Voltage on the right trace or test point. I'm not afraid to scrape off some soldermask to find some copper or solder onto one side of a resistor, capacitor, connector, etc.... that voltage has to go to somewhere. Any chance anyone has photos or better yet a schematic. HA YEAH RIGHT lol

did you click on the BLUE writing in paul's question? it's a pretty good pic

by

Yes the pretty blue was so mesmerizing that I just stared at it for a while. Then when I remembered where I was I decided to click it and see if there were some more pretty pictures, then WOW! An awesome photo of the MIDDLE PIN! Too bad that's not the one I was asking about. The right pad and its two test points are gone... lifted off the PCB. The one with the void around it that is not connected to the large GND plane.

I wouldn't have asked if my answer had been covered in a previous post

BTW, anyone looking for an easier fix, I found this. Hope its the real deal... seems a little shady. For one thing, the ad doesnt specify memory size

@Josh Crowe, that doesn't seem to be a bad price for that board. I took a look at it and didn't see a memory size for it. Maybe a email to the seller would clear that up. I sent one but the more the merrier.
