I keep a few "Home Depot" lead test swabs "just in case". I did verify the efficacy, so when a lead free solder bar was swabbed, it "passed", and a 63-37" bar was swabbed, it failed.
Quick & dirty, similar to silver chromate test, objective but not quantified.
Just a note of caution in your new endeavor:
Beware of lead free (RoHS) compliant vs. compatible. "Compliant" might not tolerate higher process temperatures even though the parts meet RoHS requirements. Headers & connectors are the worst offenders.

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!
