I believe Hitachi makes a halogen-free no-flow prepreg. I also understand that standard FR-4 no-flow prepregs *will* meet the RoHS requirements at least for now. I.e. they don't have to be halogen free, they just can't contain polybrominated biphenyls (PBB) or polybrominated diphenyl ether (PBDE) - they *can* contain the ordinary bromine-containing flame retardant in FR-4 which is tetrabromo-bisphenol A (TBBPA) - and of course they can't contain lead, mercury or cadmium.
