I have had 2 DRV chips go bad on my VESC’s lately. I’m very well versed with SMT and reflow, so I figured this replacement would be too bad. I was using full lab grade equipment and could inspect for flaws with a microscope. Replacing both chips went as smoothly as I could have expected. But now, I can’t get either ESC to boot up. No LED’s or USB. It looks like the micro isn’t getting power.
Has anyone seen this? Did I botch it?
Thanks in advance for any help I get!
