I attempted to replace the sim/sd reader on this phone. (The reader had been damaged by a broken sim tray; a piece of the tray was completely stuck in the back of the reader, and one of the contacts for the sim had snapped off).
I set to work removing the broken reader: flux on, taped surrounding area, and heated up with a rework hot air gun. The solder seemed reluctant to let go, and I was worried I was overheating other components. I pulled too hard on the reader and ripped a bunch of pads off the board. (It’s amazing what you can achieve with a lot of inexperience).
Please see pictures. There is a total of 10 pads pulled out, plus one which has half lifted.
There is nothing else wrong with this phone, and I would like to fix it if at all possible; however it's not worth spending much money on, so I don't really want to send it away - I would rather have a go at it myself. I know its beyond my current skill level to guarantee a good result, but I would like to have a shot at it just for the sake of learning, and if it works, it’ll be a bonus and I'll be a very happy chap!
* Can this be repaired, or is it impossible?
* Where and how do these pads connect - i can't see any traces?
* Do I need a schematic for this board? ( I have tried scouring cyberspace without any luck, but maybe looking in the wrong places).
* Do the 8 pads round the edge of the Reader need a different approach to the 2/3 pads which are for the microSD contacts?
Any advice, comments, etc from all the gurus out there would be very much appreciated.
Hello fixers,
I screwed up - can anyone help?
