In a recent survey, we asked the following question: What are your biggest problems related to flex design? Here are a few of the answers, edited slightly for clarity.
1. We are lagging in technology.
2. None…design them correctly!
3. Stress cracking in FPC ZIF fingers.
4. We need to work more closely with our FPC fab vendors.
5. Signal integrity of signal paths through the flex and rigid parts of the PCB.

We’re still not officially into summer yet, but Atlanta is bringing the heat, baby! It’s hit 97 degrees a few times this week, and I now have a fan aimed right at my face. At least it’s nice and humid too. I’m glad I don’t wear make-up. And it’s been a hot week in the circuit board community. This week, Eltek reported a fire at a board shop in Israel, and Flex committed to building a 145,000-square-foor facility in Jalisco, Mexico to serve the electric and autonomous vehicle segment.

With the current design transfer formats, rigid-flex designers face a hand-off conundrum. You know the situation: My rigid-flex design is done so now it is time to get this built and into the product. Reviewing the documentation reveals that there are tables to define the different stackup definitions used in the design. The cross-references for the different zones to areas of the design are all there, I think. The last time a zone definition was missed, we caused a costly mistake.
