IsoClad 933 2-Layer PCB (62mil Thickness, Black Solder Mask, White Silkscreen) for High-Frequency Conformal and Radar Applications

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

Overview of IsoClad 933 2-Layer PCB

The IsoClad 933 2-layer PCB is a high-performance printed circuit board designed for advanced RF and microwave applications. Built with IsoClad 933 laminates, which combine nonwoven fiberglass with PTFE composites, this PCB provides excellent electrical performance, dimensional stability, and mechanical flexibility. Its low dielectric constant (Dk = 2.33 at 10 GHz), exceptionally low dissipation factor (Df = 0.0016 at 10 GHz), and isotropic mechanical properties make it an ideal choice for high-frequency designs.

The final board is fabricated to a thickness of 1.6 mm (62 mils), finished with Electroless Nickel Immersion Gold (ENIG) for superior reliability and solderability. With a black solder mask on the top side and white silkscreen overlay, this PCB combines visual clarity with advanced surface protection. Manufactured to IPC Class-2 quality standards, each board undergoes 100% electrical testing to guarantee performance and reliability.
