Frequently Asked Questions

What MOQ should we expect?

It depends on the line and the test fixture. We quote honestly.

Can you take a Western brand through ATEX or FCC?

We have certified products on the line. The cert lab still owns the mark; we own the design and the evidence pack.

Is Hardware Manufacturing a different page?

Yes. The program overview is on Hardware Manufacturing. This product is the commercial SKU for DFM or contract manufacturing.
