Chosen Solution
I purchased a DIY game, that you assemble yourself. I soldered an 8x8 led matrix box in the wrong direction and had to de-solder it. After cleaning the PCB eyelet’s, I attempted to re-solder the matrix box, but the solder won’t stick. Can it be fixed using a conductive silver paste adhesive ??
@fixpcb we would have to see both parts. Most likely cause would be that you’ll be missing some solder pads etc. Adding images to an existing question
