/21 /24 /26 /121 /124
370 TURBO is the new standard in a high performance FR-4.
The 175°C glass transition temperature (Tg) and 340°C degradation temperature (Td) make it the best choice for the most thermally demanding multilayer Printed Wiring Board (PWB) applications. The application of TURBO manufacturing and curing technology to the industry-leading 370 system provides this dramatic improvement in thermal performance and reliability. TURBO technology also results in faster curing, allowing lamination press cycle time reductions of 30% or more. This combination provides not only improved performance but retains FR-4 processability, with mechanical, chemical and moisture resistance and laser fluorescing and UV blocking properties that equal or exceed the performance of any other FR-4 material available.
