Shengyi SF305 Flexible PCB Material for Compact Electronics
Highleap Electronics offers Shengyi SF305 flexible PCB manufacturing and assembly for mobile, wearable, and space-constrained electronic applications.
What Is Shengyi SF305 Flexible PCB Material?
Shengyi SF305 is a high-performance flexible copper clad laminate widely used in mobile electronics, wearable devices, antenna modules, and other space-constrained applications. It features excellent flexibility, low water absorption, and strong dimensional stability—making it ideal for modern compact circuit designs.
This RoHS-compliant material supports lead-free processing and meets UL 94 V-0 flammability standards. SF305 can be etched like standard copper-clad materials and is compatible with chemical processing methods such as ferric chloride etching. Despite its thin profile, it offers impressive electrical insulation and physical strength.
At Highleap Electronics, we integrate SF305 into flexible PCB prototyping and full-scale production. Whether you’re developing a flexible sensor, a foldable display, or embedded electronics for wearables, our factory is ready to deliver precise, reliable results.
