Inspecting DFN (Dual flat no lead) Packages



What are the requirements and how do we implement inspection process for DFN (Dual Flat No Lead) packages? Can this only be accomplished with x-ray?

Thinking of test from a structural perspective, this is a hidden joint and that makes it a viable candidate for x-ray inspection. X-ray inspection is perfect for hidden joints. That said, a good electrical solution would come with some of the advances in the in-circuit test arena. Agilent specifically has a new iVTEP solution that is less reliant on the leadframe (compared to Testjet/VTEP) to capactively couple to and therefore should be able to provide good opens coverage. Food for thought!
