Subject: Re: [TN] Board thickness tolerance on IPC spec?

As far as I know, only PERFAG 3C mentions a thickness tolerance.
Chapter 1.2: "The thickness tolerance is +/-10%" and should be measured
"just after lamination, i.e. including the copper foil of the outer
layers.", else "...the customer should consult the PCB manufacturer".

+/-10% is a common thickness tolerance for PCB.

Kind regards
Simon
