Ofer,
1) Lead is indeed allowed as an alloying element. But push back on your supplier and make HIM show you where it says this is OK and how much is allowed - and how much he is using.
2) TBBA is the common flame retardant used in most printed circuit boards. It is NOT one of the banned ones. See below what I pulled up out of the Halogen Free Archives.
PCBs, PCTs and PCNs are not used. The Halons are restricted use fire fighting chemicals. Their manufacture is banned under the Montreal Protocol and the US military will take any off of people's hands they do want. They are banking it to use for protecting vital computer installations.
3) Lead reduced will not cut it wilth an EU inspector! Just ask Sony, a la their Dutch experience.

There is no ban or proposed ban on TBBA. TBBA as reactive flame retardant
has no environmental or health concerns during use and end of life. The
bromine industry and TBBA customers will cooperate with EU authorities on
risk assessment evaluation which will take place during 2001/2002.

Dear Members
I have been asked to find out if the particular TBBA FR discussed below is
used in printed circuit boards. I know that TBBA is used in boards, but I
don't know which
particular TBBA is used. Any information, about the TBBA(s) used and CAS#s
would be appreciated.

Pronk imposes precautionary flame retardant ban
Environment Daily 1170, 04/03/02
-------------------------
The Netherlands has announced a precautionary ban on a type of
brominated flame retardant, threatening a row with some other EU member
states and the European Commission, which believe that prohibition is
not warranted scientifically and will damage the bloc's open market.
Prohibition on import, production and use of the brominated flame
retardant TetrabromobisphenolA,Bis - also known as FR-720 - was
announced by Dutch environment minister Jan Pronk on Friday. His move
responds to an application to produce the chemical from Dutch chemical
firm Broomchemie, which is a subsidiary of Israel-based Dead Sea
Bromine Group.
Mr Pronk says the precautionary action is in line with a national
chemicals policy agreed last year that sets tight deadlines for
improving the amount and quality of safety information available for
all "existing" and "new" substances. Its overall aim is to reduce
chemical risks to Dutch citizens to "near zero" levels by 2020 (ED
23/03/01
http://www.environmentdaily.com/articles/index.cfm?action=article&ref=9583).
Based on advice from the national public health and environment
institute Rivm, the government has decided that existing data on FR-720
are "too limited" to indicate even the exact nature of any possible
risks to the environment and human health, let alone their likely
magnitude.
A precautionary ban is therefore justified, the government says,
because there is too little information available to show that the
flame retardant is safe. The prohibition could be lifted, it adds, as
long as Broomchemie provides sufficient information to enable a
positive judgement to be made on FR-720's safety.
The move has infuriated Broomchemie, which defends the quality of its
data and says it is considering legal action. Meanwhile, Greenpeace
Netherlands is delighted. One of its recent campaigns highlighted
tests that showed the presence of brominated flame retardants in
household dust.
Large quantities of FR-720 are used to fire-proof of plastic household
plumbing pipes and extractor fans located above kitchen ovens and
stoves.

FR720 is surely not tetrabromobisphenol A
itself but rather the bis(2,3-dibromopropyl) ether of
tetrabromobisphenol A. Unlike tetrabromobisphenol A
itself, which is reacted into epoxy resins to make
circuitboards, the FR720 is an additive for plastics,
such as polyolefins. I have never heard of it being
used in circuitboards, at least not in the US. A Dutch
company, Broomchemie, is reported to be considering
opposing the ban.

Ed Weil

Hi Fern,
Maybe one of the laminate manufacturers can confirm this ( or not)but I
think the usual flame retardant in epoxy and phenolic resins is
tetrabromobisphenol-A (TBBA) which has a CAS No 79-94-7 and is FR1524 on the
DSBG web site. See http://www.dsbgfr.com/site/EN/dsbg.asp?PI=121z&docId=77

This is correct. The substance targeted in The Netherlands is a
dibromopropylether derivative of TBBPA. It is used as an additive flame
retardant in xxx and not in printed circuit boards. These are two
different substances with different properties and different applications..
Here is a press release by the European Brominated Flame Retardants
Industry Panel (EBFRIP):
|--------------------------+--------------------------------------|

| | Industry Panel |
|--------------------------+--------------------------------------|
| | www.firesafety.org - www.ebfrip.org|
| A sector group of | |
|--------------------------+--------------------------------------|
TBBPA is not covered by the ban on FR-720 ordered by the Dutch Ministry
The two brominated flame retardants Tetrabromobisphenol A (TBBPA) and
Tetrabromobisphenol A, Bis(2,3-dibromopropyl ether) ? also referred to
under the commercial names of FR-720, PE 68 or HP 800 - are separate
substances with distinct chemical structures, and thus different
applications. TBBPA is thus not covered by the ban on FR-720 ordered by the
Dutch Ministry.
· Distinct applications:
FR 720 is used as an additive flame retardant in two applications:
1. Polypropylene wastewater piping in construction applications.
2. Polypropylene kitchen hoods, to prevent fire ignition (e.g. from
cooking oil).
These applications help reduce the fire load within buildings and
households and enables polypropylene to comply with fire safety standards.
FR-720 is not used in the electrical and electronic industry.
TBBPA is mostly used in electrical and electronic equipment as a reactive
flame retardant in printed wiring boards (an estimated 96% of which contain
TBBPA). TBBPA is also used as a reactive or additive flame retardant in
plastics components and housings e.g. in printers and computers monitors.
· No legal restrictions against TBBPA:
There are no legislative restrictions on the use of TBBPA anywhere in the
world. There is no proposed phase-out of TBBPA under the Restriction of
Hazardous Substances draft Directive.
An EU risk assessment of TBBPA is currently under way and a first draft
Risk Assessment Report is expected at the end of 2002. All Environmental
Ministries, i.e. including the Netherlands, have given their approval for
this risk assessment process.
For more information on TBBPA, please refer to the appropriate data sheet
on BSEF website: http://www.bsef-site.com/docs/tbbpa.pdf
More technical information on FR-720 can be found on the website of Dead
Sea Bromine Group:
(http://www.dsbgfr.com/site/EN/dsbg.asp?PI=121z&docId=77).

Your assessment is correct. The material is used for plastics pipes, mainly
in Europe and Japan. The material is listed on the EU inventory list, the
EINECS, meaning no restrictions on production, marketing and use. The EU
commission, Germany, France and the UK opposed the proposed ban because
there is no science to support ban or restriction. Dead Sea Bromine Group
(DSBG), will fight the Dutch decision in court and will continue to produce
the material in alternate location and market it in EU, except Netherland.

Subject: Re: [LF] Flame retarder compliance on 2006
Hello all,
Some RoHS questions:
1. 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.
