Rigid-flex PCB assembly looks easy until reflow. Learn causes of delamination, warpage, paste issues, and how fixtures and DFM keep yield stable on the line.

What thickness of flex PCB material is best for wearables?

Posted on January 19, 2026January 19, 2026 by MC PCB Co, Ltd

Jan

Choosing flex PCB thickness for wearables? Use 0.10–0.30 mm, match dynamic vs static bend, size bend radius, and add stiffeners for real-world use. No guesswork

What are the design guidelines to prevent cracking in rigid-flex bend areas?

Posted on January 19, 2026 by MC PCB Co, Ltd

19
Jan

Stop rigid-flex cracks fast: set bend radius early, keep vias out, smooth routing, manage stiffeners, choose RA copper, and lock DFM notes for builds.

How complex is the design process for rigid-flex compared to rigid boards?

Posted on January 19, 2026January 19, 2026 by MC PCB Co, Ltd

19
Jan

Rigid-flex PCB design is harder than rigid boards because bends, stackup, transitions, assembly handling, and testing must be solved early to avoid rework.

Should I use RA (rolled annealed) or ED (electrodeposited) copper for flex circuits
