Good morning all,

We are quoting on a job (PCB Fab) and the specifications reference the
following ASTM Specifications;
- B689-97, (Nickel Plating) Type 1 or Type 2 plate, min thickness 3 micron
-B488-01, (Gold Plating) Type I or III gold, min thickness 0.3micron.

I do not have ready access to copies of the ASTM specs.  Can anyone cross
these to equivalent IPC spec's or at the least, interpret these for me into
PCB speak :) .

Regards
John Parsons
