A.K. Stamping Company, Inc. (AKS) announced today cutting-edge technology allowing one of the world's most efficient wireless charging receiver coils. Using advanced manufacturing technology, AKS coils have the highest metal density of any charging comparable coil. Currently, handheld device manufacturers are facing numerous challenges posed by incorporating wireless charging into their devices. A.K. Stamping is addressing these with unique solutions for receiver coils.
Features of the new coils include: Reduced thickness, AKS patent-pending bifilar coil design keeps the assembly thickness down to 0.3mm, including shield. Reduced heat, AKS charging coils feature industry-lowest resistance, helping reduce device temperatures while charging. Lower cost, AKS highly scalable manufacturing process offers wireless charging coils at a price point that minimizes BOM cost impact. Production yields benefit greatly from consistent inductance and resistance. Higher Power, AKS low resistance charging coils meet the higher power requirements of mobile device manufacturers, for faster charging in smartphones, tablets and other devices. And standards compatibility, AKS provides designers the flexibility to combine multiple standards such as Qi and AirFuel (A4WP / PMA) into one assembly for true multimode interoperability.
AKS expects to play an active role in the expanding wireless charging infrastructure, and through memberships in the Wireless Power Consortium (Qi) and AirFuel (formerly A4WP Rezence / PMA). The receiver coils and their unique technology reflect AKS's long-standing commitment to innovation in
AK Stamping now offers stamped, wireless charging coils and antennas. Designed as drop in replacements for wound or bent wire TX coils and wound wire or FPC Receiver coils, the benefits of AKS patent-pending, stamped coils include greater charging efficiency and reliability, while promising reduced cost and thickness for many applications.
