yes and no the deisgn is producable but to have flex as your outer layers
is not very buildable.  the flex should be in the ceneter seperated by a
few layers, the top of the board needs to be fr4, at least for our process

> Dear Technetters,

> I have designed a rigid-flex PCB of 16 layers. First 8 layer can be
> considered as a rigid-flex PCB with 2 flex layers (1st and 8th layers) and
> 6
> rigid layers (2nd to 7th layers).
> Second 8 layer can also be considered as another rigid-flex PCB with 2
> flex
> layers(9th and 16th layers) and 6 rigid layers(10th to 15th layers).
> When looked through the cross-section of the PCB, although left part is
> seen
> as 16 glued layers, right part is seen separeted in to two (2 pieces, 8
> layer rigid-flex PCBs).
>
> What I wonder is if it is possible to manufacture such a design or not?
> Thank you very much.
