Messed up the wiikey fusion a bit

Post by sl33pydog » Sat May 09, 2015 4:50 pm

So trying to fix a single pin where one of the traces had been pulled up a bit, I tried to fix it but ending up making it worse. I think I messed up the left four pins off of the connector. Is this salvageable or lost cause?

Oh and it looks like I melted a lot of it but when I got it there was epoxy all over that. I used smd tweezers to take off what I could.

It could be possible to fix this.

i circled a little area that looks suspicious...
can you clean that little line off or is it protruding from within the FPGA itself....

Turns out that was a hair. The FPGA is clean and flat.

pffffft....LOL

that hair really looks like similar to what can happen to an FPGA when it gets zapped!!

Was that supposed to be a crack and bulge?

no crack and buldge....something exactly like a strand of hair on top is what an FPGA can look like when a trace burns/blows
the traces are very thin wires connected to those legs and they can melt that black body with a hair line mark...


hope that explains how i was looking at it

It does explain it.

If I wanted to run the 3.3 and ground like the picture attached, what am I attaching the 3.3 to the capacitor and the ground to the large pad that the dip switch is connected to in the corner?
