Comparison between of the high speed VT-462S and VT-464G laminate
While VT-462S and VT-464G are both high-performance laminates designed for similar applications, there are several key differences between the two materials:
Glass Transition Temperature (Tg)
VT-462S has a higher Tg compared to VT-464G, making it more suitable for applications that involve higher operating temperatures. A higher Tg means better resistance to thermal stress, making VT-462S the material of choice for demanding, high-temperature environments.
Low Dk & Loss Values
VT-462S offers a superior low Dk and very low loss profile compared to VT-464G. This translates into better signal integrity and less signal attenuation in high frequency applications. VT-462S’s minimal loss ensures efficient transmission, particularly in high speed data communication and testing applications, where low signal loss is crucial.
Z-Axis CTE (Coefficient of Thermal Expansion)
VT-464G typically exhibits a lower Z-axis CTE than VT-462S , which is an important factor in reducing thermal stress between layers in multi-layer PCB designs. A lower Z-axis CTE ensures better dimensional stability during thermal cycling, minimizing the risk of warping or delamination in the final product.
VT-462S is a high speed laminate material with high Tg, low Dk and loss, excellent thermal reliability, and lead-free compatibility. It excels in high speed networking, IC testing, and high frequency devices. Compared to VT-464G, it has very Low Dk, lower signal loss, and improved dimensional stability. It is ideal for advanced electronics requiring top performance and reliability. In summary, VT-462S provides a versatile, reliable, and eco-friendly option for high-performance electronics.
