Baking Moisture Sensitive Components >4.5mm | 17 January, 2007

We have some larger MSL3 parts that require baking. they are 6mm thick which takes them off the chart provided at http://www.jedec.org/download/search/jstd033a.pdf Does anyone have a reference that would tell me the baking times for these components? Thanks,

Take this chance to update your documentation. See Appendix B in: http://www.jedec.org/DOWNLOAD/search/jstd033b.pdf

How much fun is that going to be? As an alternative, maybe your supplier can save you the pain.

Actually, I've been looking into this myself, and the B version doesn't help any more than the A version. The tables still only go to 4.5mm. And Appendix B has a bunch of formulas with undefined variables that I haven't been able to figure out. Anyone have some guidance on how to work this out, or some assumptions for the formulas?
