Low-rebound, high-speed transmission flexible substrate

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.

[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.

[Use Case] Supporting IoT integration through wiring wearable devices into clothing.

The conductor resistance value is low, and the change in conductor resistance during expansion and contraction is small! Suitable for applications that were difficult to apply in the past!

We would like to introduce a case where our EMS (design and manufacturing contract services) supported the IoT integration of clothing through the wiring of wearable devices. The customer's challenge was to improve the performance and quality of their own wearable devices. By using copper foil for the circuit conductors, we achieve low conductor resistance and minimal changes in resistance during stretching. This feature allows for wide application in areas that were previously difficult to implement. [Challenges] ■ Desire to improve the performance and quality of their own wearable devices ■ Traditional flexible substrates have issues with lack of elasticity ■ Unable to realize the desired wearable device *For more details, please refer to the PDF document or feel free to contact us.
