Hi,
My customer is curious as to what would cost more a 4 layer board or a six
layer board. Here are the details:
Board has 1 gnd layer an 1 vcc layer and is primarily surface mount and a
digital circuit without any critical paths. These will remain constant. The
board was autorouted for both a six layer version and a four layer version,
so here is the difference of 2 signal layers or 4 signal layers . The 4
layer was routed to 96% and 2500+ vias and the six layer routed to 100% with
1450+ vias. We all can surmise that the six layer version will be more
reliable in the long run. I am told that the cost is drilling alone is
about a $100 difference per board. Can any body help with the cost analysis?
Thanks in advance,
Scott Shepard
