[Design and Manufacturing Example] Stator Coil for Ultra-Small Motor_FPC

Base PI thickness is 25μ, Cu thickness is 18μ! A case study of coil flex design and manufacturing aimed at achieving a strong magnetic field formation.

We would like to introduce a case study of the design and manufacturing of coil flex aimed at achieving a very small yet powerful magnetic field formation, as requested by the manufacturer. Within an outer dimension of approximately 4.0mm x approximately 3.0mm, we configured a single-sided structure with L/S=35μ/35μ, 6 turns x 3 blocks. Additionally, within an outer dimension of approximately 4.0mm x approximately 10.0mm, we configured a double-sided structure with L/S=70μ/50μ, 4 turns x 3 blocks. The materials used for both the single-sided and double-sided structures are adhesive-free, with a base PI thickness of 25μ and a copper thickness of 18μ. 【Case Overview】 ■ Materials Used - Single-sided: Adhesive-free material - Double-sided: Adhesive-free material ■ Base PI Thickness: 25μ ■ Copper Thickness: 18μ *For more details, please refer to the PDF document or feel free to contact us.
