Damaged circuit path/pad on sim socket replacement
The memcard/sim socket on my Galaxy S7 got damaged after the sim tray broke and the sim card got stuck, So I tried to do the replacement procedure found here on ifixt.
Unfortunately, during the socket removal I accidentally damaged one circuit path and several soldering points :(
My question is if all of these damaged points are actually used - or if they are simply just holding the socket in place, and if some of the points are actually used, is there any way I could repair this? And how? Could conductive paint be a solution?
Below you can see what I think are left from the broken pins;
Do you think these can be used for soldering?
I think I might have double or triple posted my comment, but I really dont understand how this forum and posting works... Sorry
@minho Whats ZXW? Im a n00b at this, but I found a pic that shows what the squares are for:
@oldturkey03 I understand that the conductive paint has to connect to something, but I think there are some leftovers from the broken pins in the square. I updated my post with a closeup. If not - where are the connective circuits? Hidden somewhere in an inbetween layer of the board?
What do you mean by "shields"? I understand the meaning of the word, but not in this context. The sim socket? Or shield from outside noise, like a shielded cable?
Thx for the help guys.
@Minho Did you look at the pictures from yesterday? If you look really close you will see what appears to be something metallic on the squares. Today I used a voltmeter to see if there is any connection between the metal bits and the points where the circuits leads , and it was. Do you still think Its a super hard repair, or could I continue to put the sim socket back on? If I manage to fix the outside pads.
@oldturkey03 thx. If I was to send it in for repair I should have done it before I opened up the phone and removed the sim socket... To get it fixed now will probably cost about as much as the phone is worth. A better alternative is to buy a new motherboard from ebay I guess.
Es esta una buena pregunta?
