I have a quick question and our standard that we have maybe an older
one. We currently use the ANSI/IPC-A-600 Rev E

 

 

Page 70   Micro section:

 

There is a table describing copper plating thickness min, requirements 

 

 

                                                Class 1
Class 2                         Class 3    

Average Min Thickness              .020mm (0.0008in)        0.025mm
(0.001 in)       0.025 mm (0.001 in)

 

Minimum this area                     .0015 mm( .0006 in)       0.020 mm
(.0008 in)     0.020mm  (.0008 in)

 

 

 

Can anyone tell me if this still is a current standards for  copper
plating thickness measurements.
