TLY-5 125mil laminates are manufactured with woven fiberglass and Immersion Gold

Product Specification

Double-Sided PCB with TLY-5, 3.2mm Thickness, and Immersion Gold 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 TLY-5, a high-frequency laminate manufactured with lightweight woven fiberglass, offering exceptional mechanical stability and low dissipation factor. The ENIG surface finish ensures excellent solderability and corrosion resistance, making it a reliable choice for millimeter-wave applications at frequencies up to 77 GHz.

With 1oz copper layers, precise 7/7 mil trace and space tolerances, and a 3.2mm board thickness, this PCB is optimized for high-frequency signal integrity. Every unit undergoes 100% electrical testing to meet IPC-Class-2 quality standards.
