ERA
and Shimadzu collaborate on evaluation of ED XRF for RoHS testing Energy
dispersive X-ray fluorescence analysis (ED-XRFA) is often cited as a technique
for quick and easy analysis of the substances covered by the RoHS Directive. ED-XRF
can certainly be used to detect lead, cadmium, mercury, bromine and chromium.
The question is how does ED-XRF data from the analysis of electronic parts translate
into quantified, accurate and reproducible data which is of use in assessing the
RoHS compliance of products? The RFA group is presenting the interim results
of this investigation at the October IPC conference in Frankfurt. |
