TRF-45 Double-Sided rigid PCB built on 32mil substrates with ENIG Finish

Double-Sided PCB with TRF-45, 0.9mm Thickness, and ENIG Finish
(All PCBs are custom-manufactured. Reference images and parameters may vary based on your design requirements.)



1. Overview of the Double-Sided PCB
This double-sided PCB is built with TRF-45, a ceramic-filled PTFE laminate reinforced with woven fiberglass. It offers low-loss performance, stable dielectric properties, and dimensional stability, making it ideal for high-frequency RF applications. The ENIG surface finish provides excellent solderability and corrosion resistance, ensuring long-term reliability.

With 1oz copper layers, precise trace/space tolerances, and no solder mask or silkscreen, this PCB is designed for efficient signal transmission and high-frequency consistency. Every board is tested to IPC-Class-2 standards, ensuring quality and reliability for critical applications.
