Believe it! Although it might be necessary in certain rare cases, and as Ray says, as a bandaid, to routinely bake your boards is a mistake. For much more info, search the IPC technet archives over the last few weeks. It was a popular thread

Amazing in today's technology that people still bake because "that's the way we've alawys done it". Baking is a band aid for poor manufacturing of the PCB. Moisture can become trapped between the layers during buildup. This moisture when it contacts
