Ventec High-CTI Substrate Drives Increased Vehicle Electrification
June 4, 2020 | Ventec International Group Co., Ltd.Estimated reading time: 2 minutes
The increasingly complex typical vehicle electrical infrastructure, with many electronic control units (ECUs) positioned in harsh underhood environments where high humidity, -temperatures and atmospheric contaminants are expected, demands high reliability and durable materials for highest safety. Ventec International Group Co., Ltd. (6672 TT) has developed a high-CTI substrate (VT-441C) that offers an environmentally friendly, high-performance copper clad laminate that creates a stable and reliable platform on which to build ECU circuitry.
Increased electrification of vehicles is a trend now firmly entrenched, enabling more features, greater economy, superior reliability. ECU’s are positioned in harsh and distributed throughout the vehicle managing functions from critical safety systems such as airbag or ABS controllers to engine management and comfort features such as electric windows and electric seats. Reliability and thermal management is a must, so paying attention to the properties of materials at the substrate level is the first step towards achieving the most stringent performance targets.
The solution begins with high-performance substrate materials such as Ventec’s VT-441C high-CTI substrate that ensures reliability in the presence of high applied voltages in harsh and humid environments. With a Grade 0 (>600) Comparative Tracking Index (CTI) and a glass transition temperature (Tg) of 155oC, the versatile halogen-free material is the perfect choice for use in extreme high-temperature/humidity applications.
VT-441C is available in sheet or panel form with core thicknesses of 0.004” (0.10mm) to 0.200” (5mm).
Ventec International is a world leader in the production of polyimide & high reliability epoxy laminates and prepregs and specialist provider of thermal management and IMS solutions. Further information about Ventec’s solutions and the company’s wide variety of products is available at www.venteclaminates.com and/or by downloading the Ventec APP.

Driving Innovation: Selecting the Right Laser Source
04/28/2026 | Simon Khesin -- Column: Driving InnovationWhen I first joined Schmoll Maschinen, I brought experience from almost every PCB process, except for laser. As I immersed myself in laser processing, I realized why it can seem so daunting to a newcomer. The complexity arises from three intersecting factors: A vast variety of laser sources: CO2, UV-nano, green-pico, UV-pico, IR-pico, and others; a diverse range of applications: Drilling, cutting, ablation, and more; and an extensive list of materials: These have vastly different absorption rates. Choosing the right machine or laser source is rarely trivial. Even for experienced engineers, answering "Which source is best?" requires examining the business's specific goals.
Institute of Circuit Technology Spring Seminar 2026: A Bright Future in Europe
04/23/2026 | Pete Starkey, I-Connect007Through the leafy lanes and spring flowers of Warwickshire and back to Meridan, the traditional centre of England, and now officially part of the Metropolitan Borough of Solihull in the county of the West Midlands, I attended the Annual General Meeting and Spring Seminar of the Institute of Circuit Technology (ICT) on April 14. Out of the AGM came notable changes in leadership at the top of the Institute: the retirement of Mat Beadel as chair and Emma Hudson as technical director. Effective May 1, Steve Driver is the new chair, and Alun Morgan is the new technical director.
ACCM Unveils Negative and Near-zero CTE Materials for Large-Format AI Chips
04/21/2026 | Advanced Chip and Circuit MaterialsAdvanced Chip and Circuit Materials, Inc. (ACCM) has launched two new materials: Celeritas HM50, with a negative coefficient of thermal expansion (CTE) of -8 ppm/°C to offset the positive CTE and expansion of copper with temperature on circuit boards, and Celeritas HM001, with near-zero CTE and the low-loss performance needed for high-speed signal layers to 224 Gb/s and faster in artificial intelligence (AI) circuits.
Fresh PCB Concepts: Designing PCBs for Harsh Environments—Reliability Is Engineered Upstream
04/23/2026 | Team NCAB -- Column: Fresh PCB ConceptsWhen engineers hear the phrase “harsh environment,” they usually think of the extreme temperature swings, vibration and shock, pressure changes, or radiation in aerospace. However, aerospace is not the only harsh environment where electronic assemblies must survive. Automotive power electronics, downhole oil and gas tools, marine controls, rail systems, defense platforms, and industrial automation equipment all expose PCBs to environments that are equally unforgiving. The stress mechanisms may differ, but the physics does not.
Advanced Packaging for AI: Reliability Starts at the Cu/Cu/Cu Microvia Junction
04/20/2026 | Kuldip Johal, MKS' AtotechThe rapid growth of AI computing, from training clusters to inference at scale, is reshaping demand across the entire electronics supply chain. Advances in technology requirements, such as higher bandwidth, lower latency, and greater compute density, are driving the development of advanced packaging technologies and transforming the PCB industry across design, manufacturing, testing, and even architecture.
