You're correct that JEDEC J-STD-033 defines baking condidtions for moisture sensitive components. Why do you want to bake assemblies after cleaning? Search the fine SMTnet Archives for threads like: http://www.smtnet.com/forums/Index.cfm?CFApp=1&Me

Id say get them panelized to help lock it down in a basket or under a screen, we actually started making our own baskets out of screen material, tight mesh and not as rough. the other option would be to get something to hold them off the wash conv ho
