Unfortunately, the fab house said that they did this before. After trying
(and failing), they said that they didn't want it anymore. The Sales guy is
forcing them into trying some more. Obviously, we're not buying these
boards from them. I hope they're not listening... we haven't told them
yet.

Hey Jim,
I'm curious. Did you hear, "no problem . . . " from the Fab house
or the
Sales guy? You're giving me flashbacks, Sales booked a new order
(with
material we haven't even played with) and us Fab Engineers developed
a new
process on the fly - for a quick turn! Fortunately, my lamination
stuff
usually required only minor tweaking. I feel your pain.

Subject: [TN] CIC... ONCE AGAIN
Remember all of those e-mails back in November regarding MLBs with
CIC
layers? Well, it's time again... We went ahead and designed a CIC
board,
mainly because our present board house said "no problem, we do it
all the
time". Well, he fell on his face and now, 3 months after placing
the order,
he can't deliver. Obviously, he has little, if any, experience with
CIC.
His problem is "...inserting the invar material into the copper
tanks kills
the solution and provide no plating". He is suggesting gold plating
the
vias first, then copper plating. Has anyone ever heard of this
before? Is
this a viable solution? Anyway, we're now looking for a new board
supplier
who HAS experience with CIC. Any recommendations? This is a
prototype run
of 5 boards only.
Thanks again for all your help,
Jim Marsico
