Hi Eddie,

You are mistaken regarding the European directives.  There are no
directives that require FR-4 to be bromine free.  This is a very common
error.  The primary flame retardant in FR-4 is TBBPA and this is not
regulated by the RoHS directive.

So if you are looking to change, your drivers for change should be other
than legislative ones.

Best regards,
Dave

Subject: [TN] How about Halogen free FR4?

I've asked two top laminate mfg'rs on their status with halogen free
FR4 and both only manufacture this in Europe. I believe the
European directives require FR4 to be halogen / bromine free. Am I
mistaken or should we all be concerned with laminate also?

-- Thanks,
Eddie Rocha
