Techneters,

I'm wondering if anyone has data they'd be willing to share supporting the
18 micron minimum (class II) Final Finish, Surface Plating Coating
Requirements in the IPC-6012 and IPC-2221 specifications. Specifically, I'm
interested in the effects of reducing via wall plating thickness. Any
information would be greatly appreciated.
