Isola Brings Broad Range of Circuit Material Solutions to Electronica 2022


Reading time ( words)

Isola Group is coming to Munich, Germany and Electronica 2022 with an assortment of circuit materials expected to meet or exceed the needs of the broad range of markets the international event serves. Set for November 15-18, 2022 in the Trade Fair Center, Messe Munchen, Electronica 2022 is the world’s leading conference and exhibition for the design and production of all things electronic, from consumer products to long-lasting assemblies built for space. Isola Group will be in Hall B1, Booth #422 at the show. Isola’s material experts will welcome visitors with advice and guidance on optimum use of the company’s most popular laminates and prepregs.

Like Electronica 2022, 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 analog, 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 behavior 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 analog 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. Visitors to Electronica 2022 are welcome to visit Booth #422 to learn more.

Optimize Your Etcher for Best Image Quality

11/03/2022 | Christopher Bonsell, Chemcut
When it comes to obtaining high-quality images, many different factors come into play. Typically, most of these factors come down to your imaging equipment and cleanroom; however, there are factors involved in the etching process that can affect the quality of your image. Here are five steps to ensure your etching process is optimized for the best image quality.

Millennium Circuits on The Move

10/31/2022 | Andy Shaughnessy, Design007 Magazine
I recently met with Daniel Thau, CEO of Millennium Circuits Limited, at PCB West. This Pennsylvania-based PCB distributor has been on an expansion path lately, so I asked Daniel to introduce us to MCL and explain where the company is headed. As Daniel says, it’s all about impacting the world in a positive way.

EIPC Technical Snapshot: ‘Tremendous Uncertainty’ in Global PCB Marketplace

10/26/2022 | Pete Starkey, I-Connect007
For the past two years, EIPC’s Technical Snapshot series has kept us extremely well-informed on developments in printed circuit materials and manufacturing technologies. But what is currently happening in the global PCB market, and how is Europe and the rest of the world affected by the current world situation? The 19th chapter (coincidentally on Oct. 19) in the series gave us a privileged opportunity to find out, as two leading industry analysts presented their observations and opinions in a webinar introduced and moderated by EIPC technical director Tarja Rapala-Virtanen.
