Is there any standards for board warpage for surface mount boards?

Hi

In addition to what DaveF gave you which you should look at first

Search the archives for warp bow twist warpage etc. A Lot of treads exist.

Many of the larger OEM's and even the Mil have historically created their own documents for acceptable pre assembly bow, twist, warpage or general flatness. If you work for one get their documents.
