Wanted: Supplier of solder dissolving solution

[Phil Allison]

"Richard Freeman"

Now on to your original question the only process I can think of that
sounds even vaguley familiar (It does not involve dissolving solder
however it is supposed to be (I have not tried it) a convenient way of
removing solder at relatively low tempratures - In the order of <150C) is
a process called 'Co-metalization' described at
http://www.zeph.com/process.htm - I believe Prime electronics in Sydney
used to sell this stuff.

** The page describes a metal alloy being used to mix with existing solder,
pre-heated to 150C, to form a lower melting point alloy so that SMD devices
can be removed.

Normal 60/40 solder is soft at 180C.

A Yankee dodge if I ever saw one.


Yawn .....

Could someone tell me of a supplier in Australia of solder dissolving
solution to clean PCB's?

Thanks in advance,

Charles L

This must be a trol.

Anytrhing that will dissolve solder (usually lead and tin) will
dissolve
any other metal in the vicinity.

Then the PCB will be a dead as a DoDo.

There is in fact a product that is only available in the US as far as I
can
determine
that will dissolve solder and won't affect the copper on the PCB. I am
trying to
find out if something similar is available in Australia and I haven't
been
able to find
to date hence my original post.

Unfortunately I doubt whether I find will be able to find such a product
in
Australia.
There just isn't the market. The electronics industry in Australia is
very
small and
altogether somewhat irrelevant in the global scheme of things.
Australian
contributions
in electronic innovation have been minimal save for the 'Black Box'
flight
recorder perhaps.

What you can only come up with the Black Box ??? without even trying I can
come up with :

The Fairlight CMI/CVI
QPSX Packet switching Technlogy
High resolution Sub Surface Radar (SSR)
The Automatic Totaliser ... Oh hang on that was NZ but then again we claim
NZ Acters/Actresses and Muso's as Aussie
The Bionic Ear
Jindalee
The CSIR mk 1 was considered a world leader at the time
The Electric Drill
Telephane (early Fax machine)
the principles behind Xerox photocopying
The refrigerator
Electronic pacemaker
Teleprinter

In fact given its Relatively small population Australia actually is
significant in terms of inventions on the world stage.

Well come to think of it maybe I was a bit callous in my assesement of
Australian ingenuity.

The question is: If we can invent these things why the hell are we running
such huge trade deficits?

Now on to your original question the only process I can think of that

even vaguley familiar (It does not involve dissolving solder however it is

Thanks for this link. It is quite an interesting product to say the least.

You are symptomatic of what is wrong with this country. You have barely
enough intelligence to put your underwear on first every morning. There are
a host of other problems too.

* Our goverments (Labor and Liberal) cannnot and will not think past the
next election. As a consequence, realy big, important things don't happen in
this country.

* Labor and Liberal are both beholding to big business influences and,
therefore, will not act to preserve the future of the nation, as a whole,
but only to protect business interests.

* Company CEOs and other officers are paid obscene amounts of money, to
ensure short term gains for their companies. As a result, the real value of
many large and important companies is gradually eroded.

* In most parts of Asia (Korea, Japan, Taiwan, et al) company directors are
paid relatively small amounts of money, whilst the people who do real work
are relatively well paid. I recall reading that one major Japanese
manufacturer paid its top engineers more than all the members of the borad
of directors.

* Australian companies pay lip service to R&D, preferring instead, to buy
technology from elsewhere.

Are you willing to work for 25cents an hour?
