Frequently Asked Questions

Is First Source Electronics an ITAR-registered manufacturer?

Yes. FSE is fully ITAR registered and maintains NIST SP 800-171 compliance to safeguard Controlled Unclassified Information (CUI). The facility includes restricted-access zones built specifically for high-consequence defense and aerospace programs.

Does FSE build for defense primes and aerospace platforms?

Yes. FSE manufactures mission-critical control panels, defense electronics assemblies, mil-spec wire harnesses, and ruggedized integrations for defense primes, aerospace OEMs, and autonomous platform developers. Every build runs under IPC Class 3 workmanship standards for extreme vibration, thermal cycling, and zero-failure tolerance.

What workmanship standards does FSE use for aerospace wire harnesses and cables?

FSE builds to IPC-A-610 and IPC/WHMA-A-620 Class 3 — the highest workmanship class, required for aerospace wire networks, satellite control enclosures, and tactical vehicle assemblies. These are the standards needed to meet the extreme vibration, thermal cycling, and zero-failure thresholds demanded by defense primes.

How does FSE handle counterfeit mitigation and supply chain assurance for defense programs?

FSE intervenes at the design stage with comprehensive Bill of Materials auditing, component cross-referencing, and counterfeit mitigation protocols. Long-lead and obsolescence-risk components are flagged early, secure local cross-references are established, and every part is traceable through the full assembly lifecycle.
