FAQ

Common Questions About Working With Us.

What information do I need to provide for a technical evaluation?

Share your target product description, functional requirements, any size/power/enclosure constraints, estimated volume, and timeline. Schematics or reference designs help but are not required at the initial stage.

What is the typical project timeline?

Timeline depends on complexity. A typical custom PCBA project ranges from 4–12 weeks from requirement freeze to prototype delivery. NFC RF debugging can often run in parallel with development.

Do you sign NDAs?

Yes. We routinely sign mutual NDAs before detailed technical discussions. Your product IP and project details are treated as confidential.

What is the minimum order quantity?

We support projects from prototype (1–10 units) through pilot production (100–1,000 units) to mass production (5,000+ units). MOQ depends on the specific module and production stage.

Can you work with our existing design files?

Yes. We can take over from existing schematics, layouts, BOMs, and firmware — providing RF tuning, production optimization, or manufacturing support as needed.
