Hello,
In a previous life I was a copier service tech. Prior to laser
printers, but as most know now photocopiers use the same process.
We used to have a heck of a time with page registration, and I know
the truth of Russell's comments below having adjusted many optics
sets to<wards> 1:1...
So I'm wondering, Has anyone taken the time to see if he or she can
get a good back to back registration on PAPER?
Because if you can't get the sheet of paper to reliably go through
twice accurately; isn't it kinda unlikely that the mods to allow a
board to go through are gonna improve things?
Next, IF it is possible and likely for the registration of two passes
to line up with respect to the board edges: Has anyone held this up
to a light and checked if all the holes line up all across the board?
For a eurocard sized board?
Thank you in advance,
Ballendo
P.S. I was really getting gung ho about direct etch resist printing--
even posted awhile back about the CD tray printer I saw at Fry's, and
was talking to avecia about their resist and soldermask, when...
The above questions popped into my head. For me, if ya can't do two-
sided, it's a no-starter. SMD and SMT are not going away, and they
require two-sided layouts more often than not (means always<G>)
I truly LOVE the idea. And with a print head on a cnc machine the
registration problems go away... For others to take their place<G>
But if I'm gonna have to TT the second side anyways...
