Jeff: Last place I can recall seeing something like that is NASA-STD-8739.3 Requirements like this are not currently in vogue. A modern solder process should conform to J-STD-001, which makes no mention of prebaking boards.

Hi Steve, I think MIL-P-81728A, MIL-F-14256 and Fed std QQ-S-571/624 talks about it, but it has been superseded by J-STD-006. Hope it helps. Regards Kc.

Take a look at J-STD-003, Solderability Tests for Printed Boards. This may help you create a procedure.

SMT Rework

Sean, Are you sure that you don't mean IPC instead of ISO? If so, the the IPC-A-610 is what you are looking for. If you are doing soldering rework, then look at the ANSI/J-STD-001 too. Larry

Dave, if you have a level 6 then you have no other option then to bake it and reflow before it exceeds the specified floor life. For more details check out the joint IPC/JEDEC standard J-STD-033. It can be downloaded for free at http://www.jedec.org.

Whoa Scott, them's serious numbers!!! ;-) But then again, it depends on what you're doing doesn't it? Chris: Try ANSI-J-STD-001, which says 18-30�C, 30-70%RH Good luck Dave F
