RT/duroid 5880 PCB: 2-Layer, 40mil Core, 1.1mm Thickness with Immersion Gold Finish

(All PCBs are custom-manufactured. Reference images and parameters may vary based on your design requirements.)

Overview of RT/duroid 5880 2-Layer PCB

The RT/duroid 5880 PCB is a high-performance 2-layer rigid PCB, ideal for high-frequency RF, microwave, and Ku-band applications. With a 40mil (1.016mm) RT/duroid 5880 core and a finished thickness of 1.1mm, this PCB offers exceptional dielectric constant uniformity, low dissipation factor, and resistance to solvents and reagents. The dielectric constant (Dk) of 2.2 ± 0.02 and dissipation factor of 0.0009 make it an excellent choice for precision microstrip and stripline circuits.

The Immersion Gold (ENIG) surface finish ensures superior solderability, corrosion resistance, and long-term reliability, while the white silkscreen on the top layer enhances component labeling and readability.
