The Isola Group will be showcasing an assortment of circuit materials at electronica 2022 in Munich, Germany from 15-18 November. Isola’s material experts will welcome visitors with advice and guidance on the optimum use of the company’s most popular laminates and prepregs.
Isola’s circuit materials cover a broad spectrum of markets, for printed circuit boards (PCBs) in everything from portable electronic devices and automotive safety systems to Fifth Generation (5G) base stations and small cells and satellite communications (Satcom) systems. The materials are “made for manufacturing,” formulated with characteristics that enable different circuit materials to be fabricated with compatible processes, even when they are used to form multilayer, multiple-signal PCBs with a blend of analogue, digital, and power circuitry. Isola’s materials on display will include I-Tera MT40, I-Tera MT40 (RF/MW), Astra MT77, Tachyon 100G, TerraGreen, TerraGreen (RF/MW), and TerraGreen 400G.
These high-performance circuit materials feature key parameters, such as high glass transition temperature (Tg) and decomposition temperature (Td) to encourage compatibility of processing. The materials offer circuit designers and PCB fabricators a wide choice of circuit performance parameters, including permittivity (Dk) and dissipation factor or loss (Df), with behaviour that remains stable over wide operating temperature ranges, making them suitable choices for many growing electronic applications including Advanced Driver Assistance Systems (ADAS) and their 77 GHz mmWave radar circuits, 5G wireless communications networks, and smart energy systems.
I-Tera MT40, which is a good starting point for many high-speed digital (HSD) circuits and RF/microwave PCBs, is RoHS, lead-free process compatible and FR-4 process compatible. With a Dk that is stable with frequency (3.45 through 10 GHz) and over wide temperature ranges, it forms reliable PCBs for HSD and also microwave applications. For higher microwave frequencies, I-Tera MT-40 (RF/MW) offers Dk tailored to a user’s requirements but boasts performance consistent with time, temperature, and frequency, which is true for the general-purpose/HSD versions of the material as well.
When circuit loss is a concern, few circuit materials can match the performance of Isola’s Astra MT77 laminates (also available as prepregs without copper cladding) and their low Df of 0.0017. Also, FR-4 process compatible, these materials are ideal candidates for the mmWave portions of 5G networks and the 77 GHz radar circuits in ADAS systems. For mmWave frequency coverage where low z-axis (thickness) coefficient of thermal expansion (CTE) is required, Isola’s Tachyon 100G provide extremely high stability over frequency and temperature through 100 GHz analogue frequencies and 100 Gb/s digital rates. And for designers and PCB producers in need of high-performance, halogen-free circuit materials, Isola’s TerraGreen, TerraGreen (RF/MW), and TerraGreen 400G provide lead-free RoHS-compliant solutions usable for PCBs operating through high microwave frequencies and high-speed digital rates.
