oops -- repairing K3's KIO main board

[sussman]

I was installing the KVA transverter board this morning into my K3, and
stupidly had my finger in the wrong place while popping the KIO main-board
back into position.  One of the 4 capacitors at the top the KIO board
popped off -- at least I think they're capacitors.  I didn't recognize them
-- some sort of surface-mount transistors?  Some sort of op-amp or other IC?

After I calmed down from my panic, I managed to do a sort of hacky-solder
job to get it back on -- I'm not so good at surface mounting small parts.

That said, the K3 isn't reporting any errors, and after activating the KVA
module in the config settings, I see no error messages either.

Is it safe to assume my soldering repair worked?

I suspect it will be fine.  Soldering SMDs is pretty easy even though it's
a different skill set.

For me the hard part was learning to work with magnification so I can
see what I'm doing. :)

Yes those look to be caps, Hopefully you have it repaired :)
BTW, for a long time I was hesitant to do surface mount but now I findit quite easy a strong light and a Magnifier visor make it a lot easier.
A good set of fine point tweezers and a fine tip are about all that I use.

Congratulations you can now say you have done surface mount repair ;)

Any photos of it so we can identify the part?


I can take a photo of my own K3 later tonight -- but here's a picture of the KIO3 board from the K3 construction manual.  See the 4 nubs going horizontally along the top?  :-)  I broke off the leftmost one.
