Isola Supports High-Speed Digital Circuits at IPC APEX EXPO 2022


Reading time ( words)

Isola Group, a leading global manufacturer of copper-clad laminates and dielectric prepregs for printed circuit boards (PCBs), will be on hand at the IPC APEX EXPO 2022 exhibition with examples of its high-performance circuit materials for high-speed digital circuits, including Tachyon 100G and I-Tera MT40 materials. The exhibition is scheduled for January 25-27, 2022, at the San Diego Convention Center (San Diego, CA) and represents one of North America’s largest annual gatherings of electronics manufacturing technology and PCB manufacturers.

Isola Group will be well represented at IPC APEX EXPO Booth No. 3233, offering insights and guidance on the use of its outstanding circuit materials, in particular Tachyon 100G ultra low loss laminate and prepreg materials and I-Tera MT40 (RF/MW) very low-loss laminate and prepreg materials. The circuit materials provide stable foundations for high-speed digital circuits, including multilayer circuits in which size must be minimized.

Tachyon 100G circuit materials maintain dielectric constant (Dk) of 3.02 in the z-axis (thickness) with low dissipation factor (Df) of 0.0021 at 10 GHz across a wide temperature range of -55 to +125°C. With low z-axis coefficient of thermal expansion (CTE), Tachyon circuit materials are optimized with spread glass to provide the substrate stability needed for low-jitter data rates to 100 GB/s. They are available in laminate and prepreg forms for constructing compact high-speed-digital (HSD) multilayer circuits and circuit assemblies.

I-Tera MT40 laminates and prepregs are characterized by a z-axis Dk of 3.45 and low Df of 0.0031 at 10 GHz, both of which remain stable with temperatures from -55 to +125°C. They are cost-effective alternatives to more-difficult-to-process PTFE circuit materials for high-speed digital multilayer and hybrid high-speed digital and RF/microwave multilayer circuits. In fact, they are FR-4 process compatible for ease of hybrid circuit fabrication.

Regarding the two materials, Sean Mirshafiei, Chief Sales & Marketing Officer, said: “Circuit designers are pressing for more bandwidth, higher frequencies, and faster digital speeds for automotive, communications, industrial, medical, and military circuits. Both Tachyon 100G and I-Tera laminates and prepregs provide the characteristics needed for consistent outstanding circuit performance at the highest data rates.” 

Isola Group representatives at IPC APEX EXPO will welcome visitors to their booth with details and advice on the use of Tachyon 100G, I-Tera MT40, and other circuit materials well suited for high-speed digital circuits and high-frequency millimeter-wave (mmWave) circuits through W-band frequencies to 110 GHz. The circuit materials are FR-4 process compatible and RoHS-compliant and make cost-effective alternatives to more-difficult-to-process PTFE circuit materials for high-speed, high-frequency circuits.

Plating on Silver: What’s Old is New Again

07/07/2022 | Denis Jacques, Technic Inc.
About three decades ago, immersion silver, a nitrate-based process, gained a lot of market share in the world of PCB final finishes. More economical than ENIG, flat, solderable, and conductive, it had everything going for it—everything but corrosion resistance in a harsh environment, that is. Champagne voids were also an issue, along with line reduction. But the worst drawback, the characteristic that made the part short over time, was creep corrosion. A build-up of copper sulfide salt that grows in contact with a sulfur-rich environment, heat, and moisture resulted in failures in the field. This was enough to scar the process for good.

EIPC Summer Conference 2022: Day 2 Review

06/29/2022 | Pete Starkey, I-Connect007
Örebro, Sweden on June 15 brought a bright and early start to Day 2 of the EIPC Summer Conference for those who had enjoyed the previous evening’s networking dinner, but had resisted the temptation to over-indulge or to carry on their long-awaited catch-up conversations with old friends into the small hours. All but a few were in their seats for 9 a.m., awake and attentive for Session 4 of the conference, on the theme of new process technologies, moderated by Martyn Gaudion, CEO of Polar Instruments.

EIPC Summer Conference 2022: Day 1 Review

06/28/2022 | Pete Starkey, I-Connect007
At last, a live EIPC conference and this time in the Swedish city of Örebro, “where history and contemporary culture converge,” a pleasant and convenient location for an event that included a privileged visit to the Ericsson facility in Kumla. Around 100 delegates made the journey and the Örebro Scandic Grand Hotel was an excellent conference venue for the June 14-15 conference.
