FAQ

Frequently Asked Questions

Aluminum core PCBs are lightweight, cost-effective, and suitable for most LED lighting and power supply applications with thermal conductivity of 1–3 W/mK. Copper core PCBs offer much higher thermal conductivity (~400 W/mK) and are ideal for high-power RF modules, HPC, and precision instruments where maximum heat dissipation is critical.

Standard prototype lead time is 2–7 working days depending on layer count and complexity. For urgent projects, we offer expedited service with 24–48 hour turnaround. Mass production typically takes 10–15 working days.

We accept orders starting from just 1 piece for prototyping. There is no strict MOQ — whether you need a single sample or full-scale production, we can accommodate your requirements with competitive pricing at every volume level.

Our manufacturing facilities are certified to ISO 9001, IATF 16949, and UL standards. Every batch undergoes thermal conductivity testing, insulation resistance testing, and pressure resistance testing to ensure consistent quality and reliability.

Yes. Our engineering team provides free DFM review for every order. We'll analyze your design files, identify potential manufacturing issues, and suggest optimizations for thermal performance, trace design, and component placement before production begins.
