If you get no resistance, the trace is severed. You can save it by running a wire from the via to the corresponding leg of the NAND chip
Yes, it is a problem, the magnet wire you are using is insulated, the insulation is clear so you can't see it, but it is still there, just sticking it through the via is just as effective as leaving the end of the wire completely loose without it being anywhere near anything or not even having the wire at all. To do this repair effectively you need to melt a ball of solder onto your iron, then carefully grab hold onto the other end of your magnet wire and carefully insert the end of the wire a few millimeters into the molten solder on your iron until you get a little bit of smoke and the wire gets hot to the touch, which should take a couple seconds, then carefully remove the wire from the solder ball. The last few millimeters should be tinned at this point because you burned the insulation off of the wire so the solder was able to stick to the now exposed copper. After doing all that you can insert just the tinned bit of the wire into the via and add more solder just like you would do with any through hole component and then you will have done your trace repair.Is it a problem? It seemed a way to ensure contact to the via, as solder would wick down the copper into the via hole more easily.
EDIT: The second outer most trace is also bad. I will need to add another wire. Is there any way to test these repairs to determine if they are working?
Sadly the only way to know for sure is to power on the system. If you get colid continuity from leg to via, chances are it's goodIs it a problem? It seemed a way to ensure contact to the via, as solder would wick down the copper into the via hole more easily.

Those NAND legs are most certainly shorted. In order to clean that up flood the area in flux and apply more solder to the legs, then use wick to clean it up.I spent quite a bit today trying to repair this damage. I'm not super confident I was successful either. View attachment 23945View attachment 23946View attachment 23947View attachment 23948
It looks like you may have bridged a few of the NAND pins
That is exactly what I was afraid of. I am using 0.6 mm diameter solder currently, and I am finding it difficult to apply solder to the nand legs at these dimensions. Would I be better off ordering 0.2mm solder and working with that?Those NAND legs are most certainly shorted.

Nah you just need some decent no-clean flux. It'll help out majorlyThat is exactly what I was afraid of.

Yeah you really don't understand truly how aids it is until you have to work on the thing yourself. The NAND flex is a gift from the heavensI will say my respect for nand relocators has grown even larger, something I previously thought impossible.
