HIGH FREQUENCY / HIGH SPEED PCB

High-Frequency and High-Speed PCB

Serving high-frequency high-speed links such as 800G/1.6T optical modules, 5G communications and radar. Low-loss materials, hybrid lamination and metal-base composites — combined with line width precision and copper foil roughness control — keep insertion loss within the design window.

The material range covers Rogers RO4350B/RO4003C/RO3003, Taconic TLX/RF-35 and Panasonic M4/M6/M7, with local hybrid lamination where the loss budget allows a mixed build. Line width goes down to 2/2 mil on HDI and impedance is held to ±8%.

FAQ

FAQ

Which low-loss materials do you run?

Rogers RO4350B/RO4003C/RO3003, Taconic TLX/RF-35, Panasonic M4/M6/M7 plus domestic high-frequency laminates. Hybrid lamination with FR-4 is quoted when the loss budget allows.

How is impedance controlled?

Tolerance is ±8%, verified by coupon test on single-ended, differential and coplanar waveguide structures.

Do you build mmWave radar boards?

Yes — millimeter-wave radar boards on PTFE and hydrocarbon laminates, with line width and copper foil roughness controlled together.
