on July 1, 2006, it impacts the electronics industry worldwide."

Here in Arizona we've decided to ship all our hazardous waste to
Massa2shits ;-)

Actually, according to the spreadsheet above, nothing is underway
in AZ. But Newark's point is that everyone in the industry will
be affected, even if their own state (or country) isn't involved.

That's probably why China is going all gong1 he2 (gung ho) on the
adoption of RoHS.

I'm going electrolytic gold on a batch of PCBs now because of this,
but not yet lead-free on the assembly.

I've just read the materials that fall under the RoHS and I wonder what is
going to happen to NiCad Batteries ? The list also includes: Mercury,
Cadmium, Lead, Chromium VI, PBB and PBDE.

NiMH batteries can't provide enough discharge current to replace NiCads, so
what are people going to be able to use in model RC cars/planes ?

Regards

Andrew

Just that I'm ordering the boards with gold plating rather than the
usual HAL solder plate.

There are numerous exceptions.
For example, lead in car batteries will persist. I think the same applies to
NiCd cells where there are no alternatives (yet). AFAIK, NiCd are explicitly
allowed in electric hand tools.

Most probably, lead-free HAL will also become a standard later this year.
Til then, many people use chemical tin, silver, or gold as "intermediate"
finish, depending on the needed storage time (and financial resources

).

Sure does.

Some of our suppliers have already indicated price increases to cope with
the new processing required. Lead free solder is more expensive for one.

I'd love to know if anyone has done any research as to the effect on
reliability of semiconductors as a result of being processed at
significantly increased temps. Esp as the semi vendors have always said
that process temps should be minimised.

Frankly sounds like a bag of shit.

Trouble is - we've got used to being treated like shit. Who cares anymore
?

The elimination of Pb in electronics goods is a shockingly marginal
example of reducing hazard too.

Uh ?

Most Chinese outfits simply don't do anything to the pcb copper foil other than
cover it with laquer to stop it oxidising. Much cheaper. Why use an unnecessary
process ?

I've heard of some serious problems with solderability of the
lead-free HAL after relatively short storage (basically the boards are
scrap).

For what's it's worth I can tell you that the boards from the PCB house

I'm using come for many months now with a lead free HAL and that I
have not observed any difficulties soldering them even when they have
been flying around in my lab for months. Assembled a 6 month old PCB
with lead free HAL yesterday without any problem.

That's the answer to my question, thanks.

We are using gold too, but we have another reason. We have found that
with small and fine-pitch surface mount components that any
inconsistency in hot air leveling can result in pins not being
soldered or pins being shorted. The coplanarity and amount of solder
applied is better controlled when using gold finish.

It's also a big advantage if you ever have a bunch of boards made
and stuff/solder them years later. The gold stays solderable.

And, of course, it looks cool to have some bling-bling on the board...

Naturally, you *are* aware of the fact that solder will seperate from

gold; the result at best being an intermitttent contact...
