Double-Sided PCB with TP980, 4.1mm 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 constructed using TP980, a high-frequency thermoplastic laminate with ceramic and PPO resin composition. The absence of fiberglass reinforcement ensures smooth surfaces and precise dielectric properties, making it ideal for microwave and RF designs. With a 9.8 dielectric constant (Dk) and low dissipation factor (Df) of 0.0012 at 10 GHz, the TP980 core enables stable performance even in demanding conditions.
The ENIG surface finish enhances solderability and provides long-lasting corrosion resistance. Designed with 100% electrical testing to meet IPC-Class-2 quality standards, this PCB ensures reliability and consistency for critical applications.
