Experience and step-by-step clear explanations on soldering VFX internal boards

Experience and step-by-step clear explanations on soldering VFX internal boards

2000-11-20 by frederic@hardouin.net

Hi VFX'ers !

During my last live gig, this tricky calibration problem showed up...
I fixed it *dirtyly* as usual, by pressing all keys down with my left-
forearm.
Now I want to fix the damn problem for good !

So I got the information on soldering the boards. Got the info from 
the EPS/Chicken/Rub/*something* site too. I already opened up the 
beast a few time so I'm ready to do whatever it takes to clear out 
this problem.

I would like to have experience of members on this list who did this 
soldering by themsleves (successfully, I mean). I'm interested in 
clear step-by-step explanations. Digital photos are welcome ! Also 
where and what to take great care of...

Another thing: sometimes, my VFX just hangs, with a very loud *klang* 
sound. I hope that this problem is also linked to the calibration one 
! If not, what is the work-around ?

TIA,

Fred
