Just out of curiosity, what was the fail rate for that rework?

I don't repair/upgrade iPhones or anything, and I'm an EE not a trained technician, but I do need to swap BGAs from time to time and my rework rate for 0.4mm pitch BGAs is not the best. It works say, 3 of 4 times. But compared to colleagues I'm pretty good. But that rate is way too low to run any kind of viable business, I would think.

In this situation you're doing literally the same rework over and over, which helps, and probably have equipment and stencils specific to the job, which helps.

So I'm curious what kind of success rate was achieved if you don't mind sharing.
