There's also a kit availiable from www.LeadCheck.com. The kit consists
of swabs that have a lead reactive dye inside.

You can find a reasonably sensitive, inexpensive and quick spot test
kit
for lead at the following site:

http://www.leadinspector.com/

I'm not too sure that I will use it for more than a quick
verification.
If the part fails or is borderline I'll probably go to a more
sensitive
analytical method.

Ingemar/Joe,

I don't know about your part of the world but our labs are expensive.
If
we were to test everything that came in we'd go broke!

What really needs to happen is for the component industry to adopt a
universal code that will identify the lead finish. [L] for lead, [T]
for
tin, [G] for gold, etc. or something like that. They would add this to
the end of their part number and it would resolve all questions.

My 2C worth,

KennyB

Joe,
we are thinking likewise. Best of all is of course to have good and
reliable suppliers, and make clear specs that tell them what you want.
Unfortunately, that's dreaming about component paradise.  So, we need
to
be realistic and check  to be sure. In my opinion there is one
reliable
and good and fast  way to find out about the finish:

1. cross section a sample and have a look in a metallurgical
microscope.
2. if you are still uncertain, send the samples to someone with an EDS

why buy an EDS? There are plenty of analysis labs around.
