Hello, There is an intention for my group to go into rigid-flex and I have the following questions that I hope some of the kind soul can help : 1. When is rigid-flex most cost-effective to be used? 2. How much increase in cost compare to rigid? 3. Who are the low production (prototyping) vendors that can support rigid-flex at a reasonable price? 4. What is the possible design and fabrication process problems that will encounter? 5. Is there a software that can accommodate both rigid and rigid-flex layout design? My company used Mentor Graphics. I am aware of the IPC standards for flex and rigid-flex and books but I would appreciate sharing of opinions and feedbacks on design and process problems encounters. Hope to hear from you soonest.
