Dear Jerry,
Please continue to bake, while not baking might not affect every batch or
every part, there is a good chance that you will see various issues if
baking is not completed.
From my experience we have seen failed vias due to explosive delamination as
the main issue.

Subject: [TN] Flexible PCB's
TechNetters,
We reviewed documentation from a flexible PCB manufacturer and saw that
they recommend baking of the flex boards prior to assembly even if they
are brand new boards in a Moisture Barrier Bag.
Why wouldn't these be handled like any other moisture sensitive
component?
How many of you that work with flexible PCBs are baking them even if
they come out of a MBB with A HIC card that shows no real moisture?
Thank You,
Jerry Dengler
