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).
