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.*
