Good day, Are there any IPC standards applying requirements to HASL PCB shelf life? Are there any exact figures such as one year for instance? Could you point me to standard numbers if they exist. Iny input would be appreciated. Regards, Pavel

I don't believe there should be any issues with the HASL finish. The issue is how long on the shelf and is a bake out required to remove moisture from PCB, as in any FR4 PCB's that may have had time to absorb moisture.

You can find the spec on the IPC website in download format. Just type "Smema standards" in your search box and go Regards

Hello Billy!! IPC 7095 covers all the design rules and guide lines in BGA assembly and inspection, this will help you a lot in your problem...But based on your problem, it seems that all the balls were disappeared, try to check the capability of

Try IPC-7095 at ipc.org. It is a complete reference on Design and Assembly Process Implementation for BGAs. Glenbrook Technologies was instrumental in the developemnt of this document

Is anybody using IPC TR-640A? This is a troubleshooting checklist for wave soldering. Is it worth looking at?

Has any anyone established / published quality standards for BGA solder joints? Is IPC-A-610 in process of adding standards for BGAs?
