I just picked up a bluescreen switch (it came with the power adapter and charger so is a good deal even if I mess it up). I have double checked for obvious shorts and cant find any. The switch has a broken screen also, and was clearly bend at some point. The board is only slightly bent, at the point where it gets narrow (near BQ). I presume that during the initial bend, solder under the SoC cracked / came away (though I guess it could have ripped pads also…).
I figure the first thing to try is just reflowing it, but it was mentioned in another post that the SoC doesn’t stand up well to too much heat.
Is it possible to reflow entirely from below? It seems the biggest risk of doing so would be the capacitors falling off, if the bottom was covered with copper tape first, could I heat the bottom to 400+ to reflow without the risk of killing the SoC?
Just some extra info, I have just connected it to the PC, and it was detected fine. When injecting it completes, though 0x0000, so not hackable.
