Frequently Asked Questions

Does localized California production cost substantially more than Asia alternatives?

Misconceptions persist that domestic California production cannot compete on electronics manufacturing costs against foreign regions. However automated smart factory innovations enable California factories achieving near cost parity thanks to logistics, reliability and IP security advantages saving hidden overheads cancelling wage gaps to within ~25% cost premiums.

Why not just rely on large global EMS companies instead of California partners?

Leading global electronics manufacturing services (EMS) firms undoubtedly produce superb quality at high scales. However California startups often struggle navigating their rigid factory hierarchies shoehorning into rigid commodity workflows. Nimble regional shops alleviate friction through better aligned motivations and incentives understanding early stage engineering driven customers distinctly. They embrace the art of small volume manufacturing still with excellence.
