Small Batch Electronics Production in Spain

Opotek coordinates small-batch electronics production for pilots, B2B devices, lab equipment and niche products, covering PCBA, enclosure, firmware programming, functional test and packaging. It suits startups that cannot yet reach contract-manufacturer minimum order quantities.

  • Based in Barcelona
  • NDA by default
  • IP ownership: your choice

What is included in a small batch?

  • PCB assembly and enclosure parts.
  • Firmware programming and end-of-line functional test.
  • Test fixtures and programming jigs.
  • Serial numbers and per-unit test logs where required.
  • Labeling and packaging.

When should I move to a contract manufacturer?

When volume and design stability justify tooling and minimum order quantities. We tell you honestly when that point arrives and prepare the handover.

Frequently asked questions

Can you produce small batches?

Yes, for both the electronics and the mechanical parts. We coordinate PCBA, programming and functional testing, and we also manufacture the mechanical side: FDM and resin 3D printing are available in-house, and we work with trusted partners for machined parts and SLS or MJF printed parts. Contact us with your expected quantities.

Do you design test fixtures for production?

Yes. Test fixtures and programming jigs are part of our production support.
