Graham,
You get what you pay for. I recommend a Fischer XDAL.  Oxford has some good
offerings, as do Shimadzu and other companies that have been selling XRFs
for metal thickness measurements.  If you buy one, make sure you buy one
with apertures of the size you need for the leads you will want to take
measurements on.  You are looking at at least $50K.  I know one of the
Shimadzu ones can pull a vacuum in the chamber which allows you to detect
lighter elements than my Fischer, but this is even more $$.

I would NOT recommend a hand held unit, especially for use in Canada. Not
only will you have to abide by any provincial legislation, you will also
have to comply with the federal Red Act, which is pretty onerous.  Take a
course, another course for an instructor with a written test, eye test,
color blindness test. I was told these things sequentially by a dealer, NOT
up front and when I then said I didn't wan this device, he said since I had
accept at our delivery dock a smaller portion of the accessories for the
device that if I wanted to "return" the handheld, which I had not actually
taken possession of, that there would be a 20% restocking fee - on a $42,000
piece of equipment.  Ouch!

Gabriele has given good advice about the lead swab tests.  Good for a really
rough first go, but would never stand up to scrutiny by ECHA.

Way around this?  When you ask for certificates of compliance for the
components you buy, demand an accompanying chemical test report that stands
behind the CoC. Preferably the report is from somebody like Intertek or SGS.

Regards,
Bev

Subject: [TN] lead free (RoHS) testing in manufacturing

Good day TechNet
We are a late arrival to the lead-free party, as our customers thus far 
are exempt.  But a couple of them see the writing on the wall and are 
moving toward RoHS compliance.  Which leads me to two questions with 
regards to our testing of parts to ensure compliance.

The first question - what XRF?  We are concerned with price given that 
we are dipping our feet here, does anyone have a recommendation for a 
good but inexpensive unit?

Second question is concerning alternative test methods, a customer is 
planning to use 3M LeadCheck swabs (LC-8S10C) to ensure no lead.  Given 
that the product is described as for use on painted surfaces I don't 
think this is intended as a way to verify lead-free status on 
electronics.  Any comments on this?

Thanks!
