What is the halogen free & mid-Tg VT-441 material?
The glass transition temperature (Tg) of VT-441 is 150°C, it features a mid-glass transition temperature (Tg) FR4.1 composition. Maintains its mechanical and electrical properties under moderate thermal conditions, suitable for standard reflow soldering processes. It is formulated as a halogen-free material, offering significant environmental and safety advantages over traditional brominated flame retardants. This eco-friendly composition ensures compliance with stringent environmental regulations such as RoHS and REACH, making it suitable for global markets.
VT-441 exhibits exceptional resistance to conductive anodic filaments (CAF), which can cause short circuits and reliability issues in high-voltage applications. The material’s high CAF resistance minimizes the risk of filament formation between conductive layers, ensuring long-lasting performance and reliability. This property is crucial for maintaining signal integrity and preventing failures in high-voltage circuits, especially in environments prone to moisture and humidity.
