I don't think the average board house can build a .063 with a =/- .002. Is
this a proto-type or production requirement? You may find someone to build
it in a proto-type run but you may be hard pressed to find someone to take
it in production.

Subject: [TN] Tolerance on board thickness


Hi Technet,

It's quiet on Technet. Or is it just me ? Problems with the server again ?
Compensation for all the double messages from a few weeks ago ?
Anyway, I've got a small question :
We've ordered a 4 layer FR4 board with a thickness specification of 1.6 +/-
0.05 mm. The supplier says he can't build it with such narrow tolarances.
The customer won't accept anything worse than this.
What do you think, should the average fabhouse be able to build a board like
this or is it completely unrealistic ?
Hope to hear from you.

Kind Regards,

Daan Terstegge
