Hi,

Does anyone have an idea what is the (very) high volume (100k+) price difference between six layer (4Sig, 2planes) vs 10 layer (6sig, 4 planes). Or, any web based calculator (haven't had luck locating one) for high violume PCB. I am inclined to try with 6layer, but then the traces must be 4mill and not well protected, I am facing EMI/EMC issues from outer high speed layers. 10 layer PCB is a safe bet, but then the price could be prohibitive. I tried to get a quotes, but the typical reply is "send us gerbers first".... The board is 8x7 inches.

thanks,

I would expect that about 2x layers would cause 2x prices. One criteria is that a cheap product that does not pass government radiation standards will not be allowed to be sold and so is worthless.

Thanks,
I did found some Chinese companies, the rough price per sq inch is 0.5$for 10 layer and 0.3$ for 6 layer PCB. On a large (50sq inch) PCB the difference is 10\$. It can probably get cheaper w/negotiation for very high volume, but I agree, 6layer can turn out to be too noisy.

Sales will not waste time to give prices to customer who is just walking away without any true buying intentions.

with a gerber, at least the price could be calculated precisely. there are much to be considered when quoting on PCBs.
