Interesting. I guess maybe you could repair a multilayer board that had a hole in it by milling down the edges of the hole in kind of a stair-step pattern to expose each inner layer and then attach your patch. That would be quite a job.

I bought a dead Korg Trinity synthesizer (for £50) a few years ago some chump had poured a cup of tea inside and it burned up a few traces, fortunately all power ones. I would have actually done those steps but after doing a year of rework on 4 layer boards (my first job!) I couldn't face the job. Stripped it down and sold the keybed and chassis parts on ebay and made enough to buy a Korg Triton so I was happy.

  This is somewhat off topic, but since you mentioned it and I rarely see anyone into such things: I have a Korg Triton Extreme with a dodgy joystick (it gets stuck on the pitch bend), how easy a job do you think that would be to fix?

    That's handy: I fix them for a hobby so :-) It's a pretty easy fix. I'd buy a new joystick and replace it yourself though rather than repair the unit. It's possible but I've never taken that assembly to bits. The Tritons are built to be repaired so it's pretty easy to replace the joystick assembly. If it's like the Triton Studio (what I have) or Pro which I suspect it is then it's a case of undoing the large base screws, taking the base off and the joystick assembly can be removed easily with a few screws around the edges. There will probably be a long cable that attaches it straight to the motherboard and that's it. Careful with the cable when putting it back as they can get trapped and sheared if you don't route them properly. You can get the parts from ebay usually but you might have to wait a bit for one to appear. Either that or Korg can send you parts out from their service center. They're pretty good, reasonably priced and have bits going back to the 1980s in stock!

What a beautiful website.

Great link, I knew I'd seen something like this before. I wonder roughly where the board cost makes this level of massively labour-intensive rework cost-effective. Unless parts/plans are totally unavailable, I'd have thought respinning the board would probably work out cheaper unless it's something really weird.
