Stencil lead contamination test | 20 January, 2015

Hello

We are currently cleaning stencils from both process (PbSn and lead free) in the same cleaning machine. A customer is concerned about cross contamination of lead between stencils.

Is there any test kit or tool that you can suggest to test the level of PB contamination on a stencil?

There are a lot of lead testers out there. Just google it. I personally don't think you will find anything wrong, but for the pleasure of your customers buy one and prove it. I would also check the lead on the squeegees of your stencil printers and the lead levels in the reflow oven as well.
