370 TURBO®
4.1 Dk , 0.02 Df
175 Tg , 340 Td
/121 /124 /21 /24 /26
370 TURBO is the new standard in a high performance FR-4.
The 175°C glass transition temperature (Tg) and 350°C degradation temperature make it the 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.
