Frequently Asked Questions

What is HDI PCB and why is it important?

HDI (High-Density Interconnect) PCBs use microvias, fine lines, and high layer density to enable smaller, faster, and more reliable electronic devices. They are essential for smartphones, IoT, and 5G technologies.

Can you produce impedance-controlled boards?

Yes, Runtek offers precision impedance-controlled PCBs with tight tolerances, ideal for high-speed digital and RF applications such as servers, optical modules, and 5G base stations.

What materials do you support?

We support FR-4, HF (high-frequency) materials like Rogers, polyimide for flex, and metal-core substrates. Material selection is optimized for frequency, thermal, and mechanical requirements.

What is your lead time for prototypes?

Standard prototype lead time is 5–7 days. Fast-turn options are available. Production lead times vary based on complexity and volume.

Do you offer DFM support?

Yes, our engineering team provides free Design for Manufacturing (DFM) analysis to ensure your design is optimized for yield, reliability, and cost-efficiency.
