I used to design flip chip on flex, If you would like I can put you in touch
with some engineers in southern California who do this stuff all the time,
and I am sure they can answer most if not all of your questions.
Let me know.

Subject: [TN] Flex Query
Hello,
Looking for answers to the following questions :
1. Beside doing a "doll-house" method to model a 3-D flex design, is there
any CAD software in the market that can do it in a less painful way?
2. What is the highest frequency range a flex material can be used for? or
which flex material currently in the market can achieve 4GHz range?
3. Is there any difference between designing RF & video signal on flex as
compare to rigid?
4. If I have EMI requirement, what would be a better choice?
(a) Shield the critical signals between two ground plane (hatched or full) -
3-layer flex
(b) Critical signals on single flex with two single ground planes - bookbind
method
(c) Critical signals on one side and other side with silver plating -
two-layer flex
(d) other suggestions?
Hope to hear from everyone of you soonest.
Thansk and regards,
Wee Mei.
