Introduction to RF-35 Material
Taconic RF-35 is an organic-ceramic laminate reinforced with woven
glass, specifically designed for low-cost, high-volume RF and
microwave circuits. The laminate features a low dissipation factor
and ultra-low moisture absorption, ensuring minimal phase shift at
high frequencies.
The material’s enhanced peel strength even for 1oz copper makes it
ideal for applications requiring reworkability. Additionally, it
provides excellent dielectric stability, ensuring reliable
performance over a wide frequency range.
