Bill,

Actually you can find the copper thicknesses in IPC-4101. There should be a table in the document that correlates designation to both English and Metric units.

William, The answer is "it depends". I suggest you take a look at IPC 6012 assuming you are working on a rigid board. Brs, Gerry  > Date: Wed, 29 Aug 2012 08:29:13 -0500
