What does MSL 4 on a component package means? | 3 January, 2002

Hi,

I am trying to write SOP about the baking requirement of some CSP and uBGA components, the label on the packing said its usable within 72 hours and follow the MSL 4 condition, what does the MSL means? is it Material Safety Level? Has anything to do with the baking condition? Where can I get information (Free) about the baking standard of SMT component?

Thanks

MSL is "Moisture Sensitivity Level", and you should be able to find information on the websites of individual component manufacturers. For example, take a look at Infineon;

In addition to a previous poster's comments, you many want to understand moisture sensitive components better. Start with: * J-STD-020 and J-STD-033. Download them here: http://www.jedec.org/download/default.cfm

* �Moisture Sensitive Components� R Roland, SMT Magazine, 10/00, p.26, 28

I know fmonette has a MSD audit check list. Maybe when he posts, he'll give us a MSD control procedure aimed at operations types.

As Dave mentioned we have put together a MSD audit checklist to insure that your internal procedure is complete and in line with J-STD-033.

It's a free download at http://www.cogiscan.com, click on Moisture Sensitive Devices to access the MSD Knowledge Base and then select MSD Audit Checklist.

I hope it's helpful.
