EAGLE for Flex Circuit Design

autodeskguest

Hello--

 

Has anyone used Eagle CAD for flex circuit design?  Is this possible or

even recommended?  If so, then what are some basic design aspects that I

should watch out for?

    Hello Nicholas,

     

    I used Eagle for a flex cable design earlier this year.  It was fairly

    straightforward thanks to some fairly specific design rules from the fab

    house.

     

    Advanced Circuits has some guidelines for Flex you can use as a starting

    point, regardless of what vendor you ultimately select.

    Probably the most important considerations are to avoid sharp bends in

    traces and to route perpendicular to the direction of flex.

     

    Probably the hardest part of the design was writing the check to the fab

    house - flex is not cheap!  In my case, the cost was more than an order

    of magnitude higher than a traditional PCB run.
