Rigid-Flex PCB Design Essentials

Designing a Rigid-Flex PCB involves intricate considerations like signal direction, energy flow, and heat management. The key focus areas can be simplified into two main aspects: placement and connection.

Placement Matters

• Pay close attention to prioritizing critical signal lines, including small signal simulations, high-speed signals, clock signals, and synchronization signals.
• When laying out the design, start wiring from components with complex connections and the most densely populated areas on the board.

Connection Complexity

Connecting the PCB components is a more intricate process that involves:

• Emphasizing the wiring of key signal lines.
• Adhering to the density-first principle for efficient connections.
• Strategic placement of high-speed signals, clock signals, and synchronization signals.
