You can if you add a note on the fabrication drawing thereby making it a requirement, or make it part of a Statement of Work, or put it in the Purchase Order.

Subject: Re: [TN] FAB: Humidity Limits?
oops... I'm really embarrassed!
I thought I was familiar with IPC-1601 (the packaging and storage part of it anyway) which is why I was searching EVERYWHERE ELSE for fabrication info, but now I discover that IPC-1601 discusses fabrication too.
I'm sorry for not doing enough homework first.
but if I could ask one question about it, I only have the Final Draft of the document and it is labelled as a "Guideline", but gives real recommendations such as specific baking parameters for various situations.
My question is, can (or should) board purchasers REQUIRE adherence to 1601?
Can we even do that (like with notes on a drawing) if the document is just a guideline?
thanks,
Jack
