Good afternoon all,

I'm in the middle of an internal debate regarding the use of the 2 IPC
fabrication documents as replacements for the old MIL-P-55110 and
MIL-P-50884.  The dilemma stems from the title of 50884 containing
"Rigid-Flex" while the title of IPC-6013 only contains "Flex".  The
questions are:  Is 6012 a replacement specification for 55110?  Is 6013 a
replacement specification for 50884?  I have a rigid-flex PCB, does one
specify 6012 for the rigid portion of the PCB and 6013 for the flex portion?
Thanks in advance for your inputs.
