Hi----
Re Dan LeVasseur's question----

"GEB" is the designation for the old NEMA G11 laminate ---- the very original GE
hetanhydride resin system laminate which served as the very first flame
retardant laminates.  Devil on drills and routing blades.  If I recall correctly
---- or at all ---- the big difference between the G10 and the G11 was the flex
strength retention but this is my best guess.    The G11 was essentially
replaced by the "GF" or NEMA FR4 because most of the usage was related to the
flame retardancy ----- not necessarily its mechanical strength.

Enjoy!!
