Double-Sided PCB with TP450, 2.6mm Thickness, ENIG Finish for High-Frequency Applications
(All PCBs are custom-manufactured. Reference images and parameters may vary based on your design requirements.)
1. Overview of the Double-Sided PCB
Our double-sided PCB is built with TP450, a unique thermoplastic material that combines ceramic fillers and polyphenylene oxide resin (PPO) for superior dielectric performance. With a 4.5 dielectric constant (Dk) and low dissipation factor (Df) of 0.0010 at 10 GHz, this PCB ensures signal integrity and minimal signal loss, even in demanding environments.
The ENIG surface finish enhances solderability and provides excellent corrosion resistance, while the 2-layer rigid design ensures structural stability. Although this PCB does not include solder masks or silkscreens, it is manufactured with 100% electrical testing to ensure performance and compliance with IPC-Class-2 standards.
