Hi Chris - IPC currently has an guideline creation effort addressing the topic of your question: IPC-1601 Printed Board Handling and Storage Guidelines! The committee, chaired by Tom Kemp and Don Dupriest, is working through its final draft efforts and should be working thru the committee review and voting activities in the near term. Look under the IPC Knowledge - Committee Home Pages - D30 Rigid Printed Board Committee - D35 Printed Board Storage and Handling Subcommittee tabs to find the latest draft of the document.

We are in the process of creating a flow down document to our board houses to ensure boards are stored, packaged and handling appropriately prior to delivery to us. I have been unable to find a standard that has any information in regards to this, but have been told there is one. I'm hoping you all couls shed some light on the subject. Thanks in advance and have a great weekend.
