* Finally, when soldered by hand, do the problem pads take solder? Yes, the XRF analysis will be interesting.

an X-ray fluroscope XRF will tell u if there is any lead in it in seconds, without damaging it.

Solderability testing and if possible, measure the plating thickness (XRF).

See if you can find someone with an XRF machine or talk to your Current Board house they probably have this equiptment if they run ENIG or Silver finishes. I would stop in with some boards your having issues with and have them measure the thickness.

We had a customer who used XRF to determine the thickness of the "tinned" layer of components - sort of what is briefly mentioned in Bob Klenke's SMTA paper - http://www.circuitinsight.com/pdf/Solderability_Testing_Protocols_Component_Re-Tinning_Me

We are planning to purchase a portable XRF unit to do our LF component testing. While we were running our first proto run of LF boards for a customer, we just happen to demo a XRF unit and found lead in a "certified Lead-free component"!!! Considerin

XRF Testing....an absolute necessity??

Electronics Forum | Thu Jan 12 15:43:57 EST 2006 | amol_kane

Hi all, while looking at some XRF equipment, a question arose as to the need for testing lead-free components at the CEM facility.....if a CEM has RoHS compliancy certificates from component vendors, is that "Due diligent enough" to absolve the CEM o
