Re: G10 = FR4 ?



  Marco,
             FR4. is G-10  but G-10 is not necessarily FR4..........
FR4. is the bromated(fire retardant) version of G-10 physical properties
are identical,and for the most part anything  purchased now days is
actually FR4.
True G-10 (ie non bromated) would probably be a special order.
