:D Hello, I was wondering why I can not select 2oz copper when I select black PCB.  I need both of those things.  I need the black PCB for aesthetics (the PCB will be visible to the end user, and it's part of my branding), and I need 2oz copper weight for thermal performance since I 'm using a linear regulator and a relatively high input voltage. Thanks for any help. These are actually make-or-break attributes for me. Thanks for any help. Cheers, Andy
