Why we surmmary the Flex PCB stiffener design guideline
There were many PCB design guideline, but few of them discuss about the flex PCB stiffener design.
So Emma has summarized some tips when should add PCB stiffener and when not design.
Read deep to learn more detail flex PCB stiffener.
Required design flex PCB stiffener condition
Here is 4 conditions required stiffener when design flex PCB board.
Components are near or in an active, or dynamic, flex zone
Component size and weight will import stress onto the flex
A large number of SMT pads make planarity critical
Connectors that require repeated insertions or assemblies require a stiffener, or something to help alleviate the stress of pads.
NOT Required design flex PCB stiffener condition
Here are 2 conditions not required stiffener when design flex PCB board.
Small “static” components do not exert a large amount of strain on the flex of the PCB.
There are no components in the flex region.
