Aly,
A few things stand out here...
You'll have to ask if they do RoHS finishes instead of HASL (solder). I've been very happy with their work down to 10-mil traces, though their accuracy on v-scoring is moderate, so allow about 60 mils between boards for the cut (which is less than the typical 100-mil route plus 20-mil spacing).
Cheers, Richard

From the board file the board is 23 x 33mm, other assumptions correct. However remember because you have surface mount and plate through components you have TWO different solder masks (one for each side). The solder mask is what gives the board the green colour.
Well I did a quick check on and min order qty with panelling up they would supply 13 boards per panel 1dm2.
Ordering as Double sided prototype quantities, with NO solder mask, and just ident and 13 boards to a panel. A quick quote of 8 panels (8 * 13 =
104 boards), and post shipping on EIGHT days turnaround is 69.93 Euros (or 48.43 pounds)!!! Less than before, but that price can be juggled bySolder mask both sides (different) Add 34 Euros
Ident removal top Subtract 17 Euros
Basically Ident or solder mask cost 17 Euros per side in tooling.
For what your board is I would consider both sides solder mask for assembly process as you have tracks between pins, and top side ident so add 34 Euros to give
103.93 Euros or 71.94 pounds for 104 boardsslightly cheaper than what you had before.
Give them your VAT number and you then remove the Irish VAT rate of 21% from that and gives a total of
85.89 Euros or 59.46 pounds for 104 boardsThat is a LOT cheaper than what you had before and straight from an Eagle file you transmit electronically.
If you want faster turnaround then you pay more.
Bog standard double sided stock that most people use by the look of it.
As at least one other person has said if the chip was surface mount variety and the pins could be swapped around (different port pins used) this could be a single layer PCB. Less copper is less cost.
Personally the board could do with tidying, but is manufacturable.

Wow Paul, I think I love you :) Not quite appropriate on here but hey I'm happy, these figures are brilliant. Best quote I managed today was £160 or so.
Will get back into this over the next few days as in hospital on Thursday and planning to nail this on the head while I recover.
Thanks, will read this properly tomorrow, will likely start a new thread on it.

That's the best 'payment' I have had for advice, even in a newsgroup :-^
Get Hospital over first! Then nail this.
I am sure plenty of people will help out, if you have any further questions.
