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.*

Next-generation flexible substrate with high heat resistance, low loss, and chemical resistance, all made of LCP!

All LCP is a high-performance flexible printed circuit board (FPC) made entirely of liquid crystal polymer (LCP) without the use of adhesives. Compared to conventional polyimide FPCs, it features high heat resistance, low moisture absorption, low loss characteristics, chemical resistance, and low outgassing properties, providing stable performance even in harsh environments. It is particularly suitable for applications that require reduced transmission loss of high-frequency signals and improved durability in environments where oils and chemicals are used.

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 ...

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.

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.

When conducting structural analysis of organic compounds, IR, NMR, and MS can be considered the three sacred treasures. If the analysis is performed correctly, it is possible to elucidate the structure of even quite complex compounds. However, actual spectra are often not of a single compound, as seen in textbooks, which can lead to significant challenges in interpreting results for beginners in analysis. Additionally, while database searches are a useful tool in structural analysis, the ability to read spectra is necessary to select the correct structure from among the candidates, not just pattern matching. In this course, we will lecture on the basic ways to interpret IR, NMR, and MS spectra, including simple explanations of principles, points to be aware of during analysis, and how to proceed with actual analysis, incorporating some exercises as well.

[Speaker] Yuri Ishii, Deputy Director, Environmental Economics Division, Minister's Secretariat, Ministry of the Environment [Key Lecture Content] This guide has been created with the intention of assisting companies in responding to the increasing demands for disclosure in various environmental fields, such as climate change and natural capital, and was published in June of the 7th year of Reiwa. The "integrated approach" introduced in this guide suggests that companies should not respond individually to the disclosure requirements in each environmental field, but rather engage with an awareness of their interconnections. Through this initiative, we aim to improve business processes under management involvement, effectively and efficiently address various environmental issues, and facilitate disclosure. The key points of the guide will be explained. [Lecture Items] 1. Expansion of environmental issues to be addressed 2. Significance of integrated initiatives and disclosure 3. Trends in sustainability-related information disclosure 4. Methods and benefits of integrated initiatives and disclosure; case studies of companies 5. Utilization of environmental due diligence for information disclosure 6. Q&A / Business card exchange
