The need to Pre-Bake depends on multiple variables: 1. Packaging from the vendor (dry packs, vacuum sealed, etc...) 2. Storage at your facility (temp, humidity, etc...) 3. Moisture absortion rate of Laminate (FR406BC is one of the highest) Other rea

Being cynical in a RoHS environment is dangerous; it might lead to "lead" dependency. I know it's not easy to accept the fact that the lead-free alloys and board finishes solder as well as my ceramic bathtub. By the way what do you guys distrust the
