Ofer: The connector guy (maybe this was me?) may not have disclosed the lead content because the lead levels in copper alloys added for machinability are all below the exemption levels in RoHS and ELV. Presumably, this is why the limit was set at that level. The level can be disclosed, but since it is exempt this may just be extra work that adds little value. If you have to know, go back to your source. Of your second list, TBBPA is a common flame retardant, especially in printed circuit boards. It is not banned by any legislation, though it must be reported, tracked and separately handled as per WEEE since it is a brominated flame retardant.

A connector data sheet, from a well known manufacture, includes the following statement: "lead can be used as an alloying additive to copper, hence the connector is RoHS compliant". No ratio of the lead in the alloy is given. Does this sound strange only to me? 2. A customer sent me the following list: Tetrabromobisphenol-A (TBBA) Triphenyl phosphates Polychlorinated compounds:- Polychlorinated biphenyls (PCBs) (CAS: 1336-36-3) Polychlorinated terphenyls (PCTs) (CAS: 61788-33-8) Polychlorinated Naphthalenes (PCNs) Halons Bromofluorochlorocarbons :- Halon 1211 (CAS: 353-59-3) Halon 1301 (CAS: 75-63-8) Halon 2402 (CAS: 124-73-2) Any idea if these materials are being used in electronic assembly and where? May be I am over-sensitive, after receiving a statement from a PBGA vendor: "as there is no lead in the component the component is lead-reduced (apart of the balls)". Nice little last word.
