Frequently Asked Questions

What files do you need for a quote?

We require Gerber files (RS-274X) and BOM (Bill of Materials) for PCB assembly. For bare PCBs, Gerber and drill files are sufficient.

Do you offer PCB cloning services?

Yes, we provide reverse engineering and PCB cloning from physical samples. Contact us for details.

What is your typical lead time?

Standard lead time is 1–3 weeks depending on complexity. Expedited options are available for urgent orders.

Are your PCBs RoHS compliant?

Yes, all our PCBs and assembly processes comply with RoHS and environmental safety standards.

Can you source hard-to-find components?

Yes, our procurement team specializes in sourcing obsolete and long-lead-time components with full traceability.
