Rick,

we go for benchtop. They can focus on narrow areas of components, so if you want to check and 0603, you only need to remove 1 comp from the reel and test it. To get the same results with a hand held, you have to take something like 20 parts out of the reel, put them in special cups and test them. Besides that, the benchtop has an xy table, electrically powered, versus the handheld that has to be fixtured on a stand and you manually move the PCB or large part.

We decided that the initial difference in price is rapidly offset by the higher effectiveness of the benchtop.

Regards,
Ioan

> We have had several customers ask if we are considering the use of XRF equipment as a screening tool for lead in components. Can anyone who is currently using or contemplating using XRF type equipment for analysis of lead content of unknown components comment on the usefulness of this technique as an additional inspection method? Is there significant differences between hand-held and benchtop installations in terms of accuracy? Is the method worth the expense?
