PCB Panelization, also called PCB arrays, are composed of multiple small boards arranged to form a larger unit. These panels streamline manufacturing and assembly processes. After the components are mounted, a depaneling process separates individual PCBs from the array.
Both types of circuit boards have their own advantages and disadvantages. Rigid-flex boards are more flexible than Fr4 rigid boards. Fr4 has a higher flame retardancy. Therefore, it is used according to the current situation. Rigid-flex boards have more industrial uses, which explains why they are more expensive, while Fr4 rigid boards have more universal uses and are therefore cost-effective.
By following these guidelines—such as optimizing trace width, minimizing via use, and ensuring proper documentation for manufacturing—you can significantly improve the performance, reliability, and manufacturability of your PCB designs.
