Electronic assemblies built to Class 3

Turnkey box builds, cable and harness assemblies and electromechanical integration, built to the highest workmanship class IPC publishes. Confirm the scope before this ships.

Class 3 is the highest workmanship standard IPC publishes. It applies where continued performance is required and where equipment cannot be taken out of service to fix a defect. We build to it as standard rather than as an upgrade.

What We Build

IPC-A-610 Class 3

For electronic assemblies.

IPC/WHMA-A-620 Class 3

For cable and wire harness assemblies.

ITAR registered and NIST SP 800-171

For defense programs and controlled unclassified information.

ISO 9001 and IATF 16949

Quality systems, with APQP and PPAP discipline.

Where the failures get caught

100% functional validation  on every unit, documented and signed off.

Environmental Stress Screening  and electrical safety screening including hi-pot and continuity.

Custom automated test fixtures  built for the assembly rather than adapted from a generic rig.

Counterfeit and obsolescence control

Counterfeit component mitigation and complete component traceability on every assembly. Component cross referencing to find alternates before an end of life part becomes a schedule problem.

Where they are built

An ESD and humidity controlled manufacturing floor inside 135,000 square feet, with full serialization and records retained.

Frequently Asked Questions

Does FSE manufacture UL-listed custom power cables?

Yes. FSE builds prefabricated, UL-listed power cables custom-built to facility specifications. Capabilities include heavy-gauge cable fabrication, automated wire prep and stripping, precision routing, and overmolded environmental connectors for harsh-condition deployments.

Does FSE build underfloor power whips for data centers?

Yes. FSE manufactures custom underfloor power whips engineered to specific data center specs, ready to install. Builds include full Hi-pot testing, continuity validation, custom labeling, and serialization to align with facility cable management standards.

What testing does FSE perform on critical power cable assemblies?

Every cable assembly is validated through Hi-pot isolation testing and continuity testing before shipment. Builds intended for defense, transportation, or outdoor applications also undergo environmental stress screening to verify performance under thermal cycling, vibration, and moisture intrusion.

Can FSE handle data center cable management for new builds and upgrades?

Yes. FSE plans, fabricates, and assembles cable management systems for both new data center builds and retrofit upgrades. Engineering teams work from your facility specs to design clean, installation-ready cable runs that minimize on-site labor and deployment time.
