Introducing a flexible printed circuit board (FPC) that balances transparency and solderability!
"Transparent FPC" is a flexible printed circuit board (FPC) that excels in transparency and heat resistance, using transparent polyimide film as its substrate. We have worked on developing an FPC that achieves both high heat resistance and transparency by adopting a highly heat-resistant transparent polyimide film, thereby solving the issues of warping and dimensional changes caused by heat during reflow. As a result, it can be applied to various fields such as wearable devices and medical equipment, which prioritize design. [Features] - Uses highly heat-resistant transparent polyimide film - Can utilize the existing design rules of conventional FPCs - Proposes new wiring styles in fields such as medical, lighting, and industrial equipment *For more details, please refer to the PDF document or feel free to contact us.
Approximately one-third the rebound force compared to conventional structures! Low-rebound FPC for communication devices that combines noise reduction and high-speed transmission.
The low-rebound, high-speed transmission FPC adopts a stripline structure and is an excellent flexible substrate for noise countermeasures using shielding materials. Compared to conventional 3-layer FPCs, it is approximately 200μm thinner and reduces rebound force to about one-third, while keeping transmission loss at the same level or lower. This innovative FPC, developed for communication devices, is expected to improve assembly workability and be used in movable parts. 【Four Features】 1. Reduces transmission loss to the same level or lower compared to conventional 3-layer FPCs and decreases rebound force to about one-third. 2. Improves assembly workability and allows for use in movable parts. 3. Enhances noise countermeasures through the adoption of stripline structure and shielding materials. 4. Supports compact device design due to its thin profile. For more details, please refer to the PDF materials or feel free to contact us.
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.

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.
Achieving a length of 100m! Introducing a flexible circuit board that can handle long-distance wiring.
The "Long-Length FPC" is a flexible printed circuit board (FPC) that can accommodate lengths of up to 100 meters without seams or folds. In addition to being thin, light, soft, and able to take on various shapes, it achieves wiring lengths comparable to traditional cables. It can be used in large FA equipment and large lighting devices, and is also adopted for wiring in space development equipment such as satellites. 【Features】 ■ Can be used as an alternative to cables ■ Weighs about 1/100th compared to cables, making it lightweight ■ Thickness is approximately 0.1mm at most, allowing for installation in minimal spaces ■ Reduces the likelihood of miswiring compared to cables, improving work efficiency during assembly *For more details, please refer to the PDF document or feel free to contact us.
