Subject: Re: [TN] Minimum Finished Copper Thickness
Finished copper thickness is generally specified as a minimum thickness
measurement per the design intent. Check IPC-A-600, 3.2.3
It is more difficult to maintain copper thickness with heavy copper and poor
distribution, it might cost a bit more and you can't go to just any cheap
shop,
but it can certainly be done consistently.
