PCB Manufacturing
Bare-board PCB fabrication — rigid, flex, rigid-flex, and HDI — through a hand-picked manufacturer bench.
PCB Assembly
SMT, through-hole, BGA, and mixed-technology assembly — prototype quantities through full production.
Cable and Wire Harness Assembly
Custom cable assemblies, wire harnesses, and overmolded connectors built to IPC/WHMA-A-620.
CNC Machining
Milled and turned parts in aluminum, steel, stainless, brass, and engineering plastics — prototype to production.
Injection Molding
Custom plastic parts and enclosures, from prototype tooling through full production molds.
Box Build Assembly
Full electromechanical assembly, integration, testing, and packaging — from sub-assemblies to finished product.
Prototype to Production
End-to-end support from quick-turn prototypes through bridge builds and long-term production runs.
Built for the hardware teams shaping what's next in St. Louis
Build approach for St. Louis programs
For St. Louis programs, our network includes domestic facilities for fast-turn and ITAR-controlled work and overseas facilities for cost-sensitive production volume. St. Louis's Boeing Defense presence and the broader agtech corridor need AS9100, ITAR, and ruggedized harness partners — our Midwest bench is structured for that mix.
A aerospace & defense startup in St. Louis needs a different supplier than a agtech OEM — SmartFab's job is to place each build on the right line in our network, not push every program through the same shop.
