If your board supplier told you baking to remove moisture is a 'recent requirement' then they are either very unknowledgeable about their laminates or just plain deceiving you. In either respect, good luck on being reimbursed.

Before we did'nt bake prior to assembly as the boards came direct from the board house, now we are seeing de-lam. They told us that it is a recent requirement that came from the material supplier that they forgot to inform us of. Ours are 12 layer, stacked vias. Currently we trying to get some money back!
