Is it possible to give me a better feel for what the biggest cost-saving
factors for a quick-turn (5 days is good enough) pwb. In general, the board
types would be Class1 end-use, smt using FR4, 8-10 lyrs, 1500 drills of 3
types. If you were to rate the following, what would be the greatest
factor?:

1. Layer count
2. Number of hole types
3. Number of holes
4. Standard material, standard thickness
5. All 1oz.
6. Stacking 2-3 drilling
7. Other

What would the order of importance be: (1,2,etc.)________________________.

 And are these reasonable things to consider/require for design?:

1.      Use standard materials - FR4 Cu clad 1oz.
2.      Standard thickness - .062 (.057-.067)
3.      Min PTH thk - .001
4.      Plating of all holes, func and non-func?
5.      Dimensioned holes within (.xxx true-pos)?
6.      Silk is white epoxy ink - 75mils min height.
7.      LPI mask
8.      No internal plane donuts - clearance pads only.
9.      All 1oz.
10.     Vias .050 pad w/ .025 finished PTH.
11.     8/7 trace-space
12.     274X
13.     Other______________.

Again these are bench test-set end-use. This is sort of a long list, but if
I can get the following one question answered I'd appreciate immensily:
During the quote process, there are some issues of internal
paperwork/protocol that can facilitate quicker time to fab. Is it reasonable
to quote a design near completion, by giving a PTHV 'range' (say, between
1200-1500 vias)?  Is there a safe number that wouldn't affect a quote? This
would be for ONE size only (the vias). Is this an unreasonable request for a
quote?
