The design of any type of PCB is where everything starts, as assembly may be more efficient there. You must take a close look at all the steps involved in manufacturing a flex-rigid or flexible PCB. Keep in mind that developing a rigid-flex PCB is more complex than a flexible PCB.
As the name suggests, PCBs that offer strength and flexibility at the same time are Rigid-Flex PCBs. These are a hybrid design that incorporates rigid characteristics and flexible PCB characteristics
Key Takeaways
Cross-hatching significantly increases the flexibility of flex PCBs by reducing copper content.
Helps maintain optimal impedance in flex PCBs without altering dielectric thickness or signal line width.
Enables efficient manufacturing with reduced copper usage and improved resin adhesion.
