Given the reactions I'm getting to ReworkCTF stuff, I'm curious...
What's the most complex PCB rework you've personally done? If you've done multilayer circuit edits, what kind of bodges and what tooling did you use?
I've seen some pretty impressive work (and done some myself in the past) using handheld rotary tools, but IMO for truly surgical multilayer rework a 3-axis (or more) mill is the way forward.
| In-kind component replacement | |
| Outer layer circuit edit | |
| Multilayer circuit edit (inner layer, via, etc) |
Successfully completed challenge 10 (missing via between front and back layers) and 11 (via from front to back shorted to power plane).
Decided not to move on to 12 (solder paste print defect under BGA) because I had just done an aqueous clean around the BGA site and wanted to bake it before doing further rework.
Will be busy tomorrow but I'll bake the board tonight or tomorrow then try to do a lunchtime stream Monday with challenge 12 and on.
Going live at 14:45 Pacific (20 minutes from now) on the next stage of the ReworkCTF.
Challenges 10 and up are mostly all fun inner layer stuff.
