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).
