Can I attach a connector meant for a rigid PCB to a flex PCB?

Is it possible to connect a standard mezzanine connector to a flex PCB? I.e. could I use a mezzanine connector meant for connecting two rigid PCBs in a situation where one is flex and one is rigid?

What is usually done is that a stiffener is added to the area of the connector. The stiffener is usually FR4 (with no copper) glued/epoxied to the flex on the backside of the connector.

However, maybe the application results in minimal bending without stiffeners. What counts as acceptable is rather dependent on the particular parts, the application, and the required reliability and lifetime, so it’s not easy to quantify.

What Others Are Asking

How can I determine BGA land pad diameter for given ball diameter?

I’m working on a project which requires the use of a CSP package. The product’s datasheet provides ball pitch and ball diameter but nothing about the preferred land pad diameter.
How can the pad diameter be worked out from these figures assuming an NSMD land?

Which soldering iron tip should I use?

All of the soldering I’ve done to this point has been with through-hole components. I hope to move up to some smaller surface-mount parts at some point in the future. I’ve got a Weller WES51 soldering station. There is a large number of ET series tips available. How do I choose the right tip for the components I’ll be working with?
