What Is FPC StiffenerHeres All You Need to Know
Flexible PCBs are common, but can be too flexible. FPC stiffeners add rigidity, structure, and support. Different materials like polyimide, FR-4, aluminum, stainless steel are used. Stiffener thickness varies. Benefits include better handling, stress distribution, heat dissipation. Stiffeners are applied using pressure-sensitive adhesives or thermal bonding. They prevent parts from falling off, maintain circuit thickness, and aid in ZIF connector compatibility. Adding FPC stiffeners enhances performance and reliability of PCBs.
