High-Speed Communication
What materials are best for high-speed communication PCBs?
Hybrid laminates like Rogers RO3003, RO4350B, Taconic RF-35, and PTFE-based materials are preferred for their low dielectric loss and stable electrical properties at mmWave frequencies.
How do you control impedance and insertion loss?
We use precise stackup design, SI/PI simulation, controlled copper thickness, and laser-etched microvias to maintain impedance within ±5% and insertion loss below 0.6 dB/inch @ 28 GHz.
Can you handle complex BGA and array connector assemblies?
Yes, our SMT lines support fine-pitch BGA and array connectors with advanced soldering and inspection techniques to ensure mechanical and electrical reliability.
What testing do you perform for telecom PCBs?
We conduct impedance testing, thermal cycling, AOI, X-ray inspection, and functional testing to meet or exceed telecom industry requirements.
What is your typical lead time?
Prototype turnaround is 3–5 days; mass production lead times start at 10 days depending on complexity and volume.
Do you provide end-to-end solutions?
Absolutely. From PCB design consultation, material sourcing, fabrication, assembly, to final testing and logistics, we offer a seamless one-stop service.
