[Production Example] Superconducting Device (Flexible for Superconducting Circuit Evaluation)

[Production Example] Superconducting Device (Flexible for Superconducting Circuit Evaluation)

Examples of superconducting devices (for superconducting circuit evaluation) operating at ultra-low temperatures of -269℃. *Source: Yokohama National University

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.

Flying lead flexible printed circuit board (FPC/flexible circuit board)

Flying lead flexible printed circuit board (FPC/flexible circuit board)

It is a flexible substrate that allows for a highly reliable connection.

By partially removing the base film, it is possible to form a conductor. By narrowing the pattern width, reliable connections to the opposing circuit or device can be achieved, similar to wire bonding. It is used in areas that require high density and high reliability, such as probes.

Ultra-fine circuit high-frequency flexible substrate

Ultra-fine circuit high-frequency flexible substrate

Combining PTFE base and low dielectric coverlay to produce various low-loss FPCs!

The "Ultra-Fine Circuit High-Frequency Flexible Substrate" is a flexible substrate designed for high-frequency applications in the GHz range, compatible with bare chip mounting. By using LCP (Liquid Crystal Polymer) with low dielectric properties as the core material and forming circuits using the SAP (Semi-Additive Process), it is possible to create transmission lines with a differential impedance of 100Ω at wiring pitches below 50μm. To accommodate wire bonding with bare chips, the mounting pads are treated with ENEPIG (Electroless Ni Pd Au plating) for surface treatment. One of the features of SAP is its high precision in circuit formation, with an accuracy of ±5μm, making it suitable for impedance control. *For more details, please download the PDF or contact us.*

Stretchable flexible printed circuit board (FPC/flexible board)

Stretchable flexible printed circuit board (FPC/flexible board)

It is a flexible circuit board that can be repeatedly stretched and contracted, and can follow deformation. FPC

While general flexible materials can be bent, they face challenges in folding and stretching. Due to their flexibility, stretchability, and ability to conform, they are expected to be used in a wide range of fields for flexible electronics devices, including wearables, sensors, displays, robotics, as well as pressure sensors and seat heaters.

[Design and Production Example] Coil_FPC for Motor Field Windings

[Design and Production Example] Coil_FPC for Motor Field Windings

A circuit is formed considering the thickness of the flexible printed circuit (adjusting the L/S pitch). For the motor's field winding (for generating a high electromagnetic field) flexible printed circuit. *Source: Gunma University

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.

Blind Via (BVH) connection Flexible Printed Circuit (FPC)

Blind Via (BVH) connection Flexible Printed Circuit (FPC)

It is a flexible substrate effective for high-density wiring. FPC

Unlike conventional through holes, to avoid penetrating the hole, a via is placed directly under the pad. Fine hole processing using lasers is possible, making it effective for ultra-high-density wiring, etc. With the miniaturization and thinning of mobile devices, as well as the enhancement of communication devices, there is an increasing demand for high-density mounting of narrow pitch, multi-pin packages. Consequently, flexible substrates are also advancing in terms of high-layer count and high density. FPC

Transparent Polyimide Flexible Substrate (FPC/Flexible Substrate)

Transparent Polyimide Flexible Substrate (FPC/Flexible Substrate)

It is a flexible substrate that combines heat resistance and transparency. FPC

Compared to glass materials, it is possible to create unique design concepts not only for flat surfaces but also for curved surfaces, folding, and wrapping, thereby expanding the design possibilities for mounted devices. It is expected to be used as a substitute for glass substrates in applications such as: - Transparent conductive substrates for touch panels - Organic EL and LED lighting substrates - Displays for mobile phones. Additionally, bare chip LEDs will be implemented on transparent polyimide substrates using wire bonding, followed by resin encapsulation. Light will pass through the transparent polyimide and beautifully illuminate the opposite side.
