Developing a rigid-flex printed circuit board is difficult enough, but when that PCB has high-speed signals as well the design can get complicated. For example, how do you determine what's more important: high-speed signal integrity or the flexibility of the circuits? PCB design is all about managing tradeoffs in the planning and layout stages, and a hybrid high-speed and rigid-flex design requires care when making these tradeoffs. To be successful when designing a complicated rigid-flex PCB with high-speed signals, follow a specific set of best practices.
