Rigid-Flex PCB design can be complex, considering the direction of various signals, energy transfer, and the effects of heat. However, the key aspects can be summarized as “how to place” and “how to connect.”
The layout is critical in the “how to place” aspect. Attention should be paid to key signal line priority, such as simulation small signal, high-speed signal, clock signal, synchronization signal, and other key signals. Wiring should prioritize these key signals. The density first principle should also be followed, starting wiring from the components with the most complex connections on the veneer and from the most densely wired area on the veneer.
The “how to connect” aspect is more complicated. It involves prioritizing key signal line wiring and following the density first principle. Attention should also be given to the placement of high-speed signals, clock signals, and synchronization signals.
