Egor Testing

[David Chambers]

Thanks for the info Daniel.
The local Asutralian places off a 12" x 14" panel for $350 Australian
($175US) with no setup costs and very good quality as a 5 day prototype
service. Repeat panels are $150 ($75US) if ordered later and $75 ($37.5US)
if ordered with initial order. I expect the EGOR boards would only be 2" x
2" so each board will cost something like $8 initially down to a couple of
dollars in quantity.
BUT I still want to make sure that I have the most uptodate circuit to do
the PCB from. I have only received one response from Mark Riley (thank you)
with an updated circuit. Has no one else prototyped one of these and
corrected the original circuit?

David,

There is a shop here in Michigan that can build the boards fairly cheaply if
we
order in quantity. They have great quality and 100% test each & every board.
Setup fee is typically $200, Tooling is typically $200, and board fee is
typically $5 to $15 each. I once got a complex four-layer board (with 60 SMC
parts incl. micro, memory, and heaps of analog stuff) made for $15 per panel
of
three, and $400 in setup & tooling fees, when ordered in a quantity of 110
panels. Once you get the Protel Gerbers together, why not let me give them a
crack at quoting it?

"Fair Go,"
