This is what i found for cheap (sort of) and quick.  It was developed by Hybrivet and NIST.  (There are other sources for the same, almost exact, thing) It's good to <0.5% - let's face it, we're looking to find if stuff is 63/37 or LF so 0.5 should do it.  It's about $2.00 to 2.50 per so it's not something to be used indiscrimately.  The reason for the indirect test is to find if Pb present without contaminating the board.  This stuff will leave a residue, if applied directly, which must be cleaned off to assure a good connection later.  There is a cheaper variety (~$0.50)  available but if you read the MSDS for it, it looks like a sulfide containing material which isn't what we want.  The Hybrivet is rep'd by Kester (No, I'm not advertising)and available through them.  A 48 test kit will cost about $115 including little abrasive q-tips and trays.

I hesitate to put this on TechNet because it is a Brand.

Is there an easy way to verify that an assembly has been produced with
lead-free solder?  Conversely, is there a quick and easy test for lead in a
solder joint?
