So, a while back, I did this thing, in which I soldered a lot of really tiny wires to a chip, because I wanted to use the chip for something:



And then a while later, I did it again, with slightly finer pitch this time I think, on a Hannah Montana video game board that Elly picked up for cheap, which we wanted to reverse engineer:



But, man... I think this one takes the cake. I had to replace two resistors that you see in the top of the following image:



Now, how small are those? Well, don't sneeze. They're the little specks below the writing.



It took me just under five hours to do it twice. Lots of fun, but certainly frustrating...

My boss recently terrified me by removing a fine-pitch BGA from a board, peeling back the solder resist, and then peeling a copper trace and relaying it to another pin, before putting the BGA back on again. I have no idea how long that took.

by hand??? BGA is awful. That's nuts!
