Chris,
Perhaps we should congratulate Canada on their highly responsible stance on
this important issue of environmental protection, and urge Canada to extend
the ban on rosin to ALL Canadian manufactured, imported or exported goods,
to the end goal of becoming a Rosin-Free safe and healthy nation?
As George Wenger has said, there is rosin in the lumber they have been
exporting. Canada must immediately cease all such lumber exports until they
can grow rosin-free trees.
Until they do enact an outright ban, I would advise other countries to sue
for damages due to rosin-contamination.
Soldering? Is anyone still using that arcane attachment technology? I
thought that with the lead ban, soldering had become passe?
Mind you, I have heard that rosin fluxes are used with a wide variety of
solder alloys, including newly developed lead-free materials. Rosin has
been particularly critical in the successful introduction of these new
solders, because many have higher melting points, and rosin maintains
effectiveness at high processing temperatures.
So I advise Canadians to beware the law of unintended consequences....

and Canadians, albiet waning somewhat if this data gathering leads to a
ban!)

Rosin (colophony) free fluxes have been available and used for years by
electronics manufacturers voluntarily wanting to reduce potential health
issues for their staff, so why this sudden issue when Canada proposes an
outright ban..... seems a little knee jerk .......

What's next, I wonder...
Will we all be forced to go back to living in caves, writing on walls (with
environmentally safe materials, of course)? Will our modern world will be
deemed too unsafe to live in? Seems that's where we are headed, doesn't it?

IPC Urges Canada to Remove Proposed Ban on Rosin
Written by Chelsey Drysdale

BANNOCKBURN, IL - IPC is urging its members to respond to Canada's Chemical
Management Plan's proposal banning five rosin-containing substances from all
products manufactured and sold there.
The trade group also submitted comments today to the Canadian Department of
the Environment in advance of the Oct. 20 comment deadline.
Rosin is used in the manufacture of more than 75% of electronics products,
including defense systems, telecommunication and transportation
technologies, IPC noted.
A ban on rosin would make it difficult for electronics manufacturers to
continue to do business in Canada, says IPC. In addition, consumers would
likely foot the bill for the increased production cost because electronics
manufacturers would have to engineer products specifically for the Canadian
market. Even more likely, Canadian electronics manufacturers would consider
moving operations to countries that do not ban the use of rosin, resulting
in a loss of Canadian jobs, says the association.
According to Dr. Greg Munie, IPC technical director, rosins are naturally
occurring materials that possess irreplaceable chemical and electrical
properties qualities that ensure a reliable, safe and long-lasting product.
There is no known chemical or combination of chemicals that can provide the
same functionality and reliability of rosin. Therefore, eliminating rosin
would force a change in the composition of soldering flux and solder paste
that will ultimately affect the reliability of the final electronic product.
