Built in ones and twos, to a drawing that changed last week.

Power, thermal and cabling infrastructure for quantum systems.

Low volume and high change is our normaloperating mode.

We build in ones and twos, to drawings that are still moving, with engineering in the same building as the floor. Quantum programs get engineered while they are being built, and that is the work we do every day.

What these systems need from us

  • Stable, low noise power

    For control electronics and instrumentation, where supply noise shows up directly in the measurement.

  • Precision thermal management

    Around cryogenic systems and the equipment that supports them.

  • Shielded cable and harness assemblies

    Built where EMI performance is part of the specification rather than an afterthought.

  • Control and instrumentation panels

    Built to the current revision of a drawing, not the one from six weeks ago.

  • Thermal management

    Cooling for enclosures and process equipment where ambient conditions work against you.

How we work with programs like these

  • Engineering before the build. Feasibility studies, FEA, and design for manufacturability reviews on hardware that has never been built before.

  • Prototype and production under one roof. The team that builds the first article builds the tenth, which means the learning stays in the building.

  • Revision control that expects revisions. Configuration management is set up for hardware that changes, because most of what we build does.

Frequently Asked Questions

Does FSE manufacture sub-components for medical device OEMs?

Yes. FSE builds precision wire harnesses, cable assemblies, control panels, custom enclosures, and electromechanical sub-assemblies for medical device OEMs. Every assembly ships with full serialization, complete component traceability, and 100% functional and Hi-pot testing, all backed by IPC-A-610 and IPC/WHMA-A-620 Class 3 workmanship.

Can FSE meet OEM supplier qualification requirements for medical device programs?

Yes. FSE builds to IPC Class 3 workmanship, runs APQP and PPAP on every program, and provides complete documentation packages (serialization, BOM traceability, test records, and configuration management) that support the audits and qualification reviews medical device OEM regulatory teams require.

Is FSE an FDA-registered medical device manufacturer?

FSE manufactures sub-components and sub-assemblies that medical device OEMs integrate into their finished products. We are not a finished medical device manufacturer. The OEMs we serve hold device-level certifications such as FDA registration and ISO 13485, and FSE provides the precision contract manufacturing that meets their supplier qualification standards.

How does FSE support long medical device product lifecycles?

Medical devices often stay in service for 10-15 years, which makes component obsolescence a real risk to your program. FSE audits your Bill of Materials during the design phase to flag long-lead and end-of-life components, establishes secure cross-references, and runs Vendor Managed Inventory programs to insulate your program against supply chain disruption. Configuration management is documented across the full lifecycle.
