Flex PCB Design Guidelines for Manufacturing

Abstract:

Designing flex and rigid-flex circuit boards calls for an advanced methodology compared to standard rigid boards. From material selection to calculation of bend radius, and controlled impedance to EMI shielding, all require a unique design approach to align with the fabrication and assembly processes. Knowing these design considerations is important to reduce the turn time and improve reliability.

What you will learn:

• Material selection for flex boards
• Types of flex materials
• Calculating bend radius
• Electrical factors that influence bend capabilities
• Controlled impedance in flex boards
• How to maintain signal integrity of your flex designs
• Cross-hatch modifications to reduce signal reflections
• EMI shielding
