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.

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.

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

[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.

High Current Compatible Flexible Circuit Board BigElec

High Current Compatible Flexible Circuit Board BigElec

The Big Elec flexible circuit board compatible with high current has three features.

Big Elec is a flexible circuit board designed for high current wiring, achieving a flat shape and thin profile as an alternative to busbars and wire harnesses. It boasts three remarkable features. 【Feature 1】 Low Inductance Thanks to its unique structure, it achieves lower inductance compared to conventional wires with the same conductor cross-section. When switching high currents at high frequencies, high inductance can cause significant voltage spikes, potentially damaging high-current electronic components. Big Elec's low inductance reduces voltage spikes, contributing to the reliability of high-current electronic components. 【Feature 2】 Flat Shape and Flexibility Its unique structure allows for a thin conductor, flat shape, and flexibility. It is flatter than traditional wire harnesses and can handle higher currents than conventional flexible circuit boards. 【Feature 3】 High Design Freedom It ensures the same design freedom and usability as printed circuit boards. Pattern wiring and external shapes can be customized to meet specific requirements. It also supports the mounting of electronic components and connectors using paste solder.

Narrow pitch pad on beer flexible substrate

Narrow pitch pad on beer flexible substrate

By directly providing vias on the pitch pad, we contribute to the high-density implementation of FPC.

By incorporating non-through filled vias into extremely small pads with narrow pitch, it becomes possible to implement electronic components at a higher density. This enables the miniaturization of flexible substrates and the implementation of multi-pin SoC chips. 【High-Density Implementation Possible】 It is possible to directly create filled vias on very small pads (φ100μm) with a pitch of 150μm, allowing for higher density component implementation. 【Easy Miniaturization】 Since high-density components can be implemented, it allows for the design of miniaturized substrates.

Low-rebound, high-speed transmission flexible substrate

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.
