Prototype to Production sourcing for St. Louis programs
End-to-end support from quick-turn prototypes through bridge builds and long-term production runs.
Our prototype-to-production programs are structured around the reality that the shop that's right for your first 5 boards is rarely the shop that's right for your 5,000th. We start with quick-turn prototype partners — 24-48 hour PCB fab, 5-day PCBA, 7-day CNC — to get hardware in engineers' hands while the design is still moving. Once the design is stable, we transition into bridge production with a mid-volume EMS or machine shop that can absorb engineering changes without re-tooling cost. From there, we move into sustained production with a partner sized for your annual volume, with full DFM/DFT review, supply-chain hardening on long-lead components, and lifecycle management on resin grades, connectors, and ICs. The handoff between stages is the part that breaks most programs and the part SmartFab manages — keeping the BOM, AVL, and test plan aligned across multiple shops so the product that ships in year three is the product that was qualified in year one.
Why St. Louis teams source prototype-to-production through SmartFab
One RFQ, one accountable partner
One prototype-to-production RFQ from St. Louis returns one accountable manufacturing quote — sized for your volume, your certifications, and your lead time.
Supply chain headache, eliminated
We own sourcing, production, and follow-up on every St. Louis prototype-to-production program so your team ships product instead of chasing shops.
Better supplier fit
The shop that builds your prototype is rarely the right shop for production — and the handoff is where most programs lose time and money. For St. Louis programs in aerospace & defense, that means placing the build on a line with the right certifications and volume profile from day one.
Build approach for St. Louis prototype-to-production programs
When we route a prototype-to-production RFQ for a St. Louis customer, we evaluate the build against facilities in our network on three axes: certifications (does it need ISO 9001 baseline plus industry-specific (AS9100, ISO 13485)?), volume (prototype, low-volume, production), and lead time. 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.
For aerospace & defense programs in St. Louis, we typically return one accountable manufacturing quote within 24–48 hours.
