• Printed Circuit Board

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.

We would like to introduce a case of flexing our substrate and wire products. We improved a product that was composed of a rigid substrate and wire into an integrated flex design. There are application examples for dental examination tables and EEG measurement sensor devices. 【Application Examples】 ■ Dental Examination Table ■ EEG Measurement Sensor Device *For more details, please refer to the PDF document or feel free to contact us.

• Circuit board design and manufacturing
• Other contract services

We would like to introduce a case study of the design and production of field winding using flexible substrates that we conducted. To wind around the main pole piece, a circuit was formed considering the thickness of the flexible substrate so that the coil wiring overlaps at the same position (L/S pitch was corrected and adjusted). Due to the long structure, we implemented correction processing considering the shrinkage characteristics of the flexible material and the etching factor of the conductor, utilizing ultra-thin copper foil material. 【Case Overview】 ■L/S=100μ/100μ ■Specifications: Double-sided structure ■Base PI thickness: 25μ (no adhesive material) ■Cu thickness: 2μ (excluding Cu plating thickness) *For more details, please refer to the PDF document or feel free to contact us.

• Contract manufacturing

We would like to introduce a case study of the fabrication of a superconducting device flex that operates at an ultra-low temperature of -269°C. Using flex materials that operate in a superconducting environment, we produced flex for superconducting devices, including single flux quantum circuits (SFQ circuits) and adiabatic quantum flux parametron (AQFP), for the purpose of verifying the operation of superconducting circuits. Laser processing was applied due to the tolerances required for the device electrode parts. [Case Overview] ■ Materials Used - 2-layer materials (2 types) - 3-layer materials (2 types) *Materials were determined after verification experiments. ■ Laser processing was applied due to the tolerances required for the device electrode parts. *For more details, please refer to the PDF document or feel free to contact us.
