Low-loss flexible substrate

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

Our company manufactures low-loss flexible substrates (GHz band, Microstrip Line). We would like to introduce a flexible substrate that significantly improves transmission loss compared to the combination of polyimide-based and standard coverlay products. Using a PTFE base with a low-dielectric coverlay, we can expect a 60-70% improvement in transmission loss at the 40GHz band compared to standard products. Additionally, while the performance is slightly lower compared to PTFE-based substrates, a combination of LCP base and LCP coverlay can also expect about a 50% improvement in transmission loss and is suitable for long-term heat resistance and low outgassing applications due to the absence of adhesives. *For more details, please refer to the PDF materials or feel free to contact us. *Abbreviation explanations: PTFE ... Fluoropolymer LCP ... Liquid Crystal Polymer

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.

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.*
