Frequently Asked Questions

What is an IC Substrate PCB?

An IC Substrate PCB is a high-density interconnect board used as a carrier for semiconductor chips in packages like BGA, CSP, and SIP. It provides electrical connections, thermal dissipation, and mechanical support at the chip level.

What materials do you offer for RF PCBs?

We offer Rogers (e.g., RO4350B), Teflon (PTFE), Taconic, F4B, Isola, and Arlon materials for high-frequency applications. These are ideal for antennas, 5G, and microwave circuits.

Do you provide quick-turn PCB services?

Yes, we offer quick-turn services with options for 24-hour, 48-hour, and 5-day turnaround for both prototypes and small-volume production.

Can you handle ultra-thin PCBs?

Yes, we have specialized capabilities for ultra-thin PCBs down to 0.3mm thickness, suitable for compact and lightweight electronic devices.
