A great place to start is IPC-2223 Sectional Design Standard for Flexible
Printed Boards and IPC-6013 Qualification and. Performance Specification
for Flexible Printed Boards.
Work with an assembler and fabricator who has plenty of experience with
rigid-flex on the lines with the people that they will give you. There are
a lot of gotchas that assembly engineers and operators with flex experience
have already learned.
