Box Build Assembly for San Antonio, TX.
Contract manufacturing for San Antonio engineering teams across box build. Prototype through production. Network certifications: AS9100 · ISO 9001 · ITAR · IPC.
Box Build Assembly sourcing for San Antonio programs
Full electromechanical assembly, integration, testing, and packaging — from sub-assemblies to finished product.
Our box-build bench takes PCBAs, harnesses, mechanical enclosures, and purchased components and turns them into finished, tested, packaged product. Scope includes electromechanical sub-assembly, full system integration, cable routing and dress, software/firmware loading, functional test development and execution, environmental burn-in, label and serial-number application, custom packaging, and direct fulfillment. We support both kitted (you supply components) and turnkey (we source) models. Volumes range from single-unit engineering builds and 10-unit pilot runs through sustained production of thousands of units monthly. Workmanship to IPC-A-610 and IPC/WHMA-A-620 Class 2 or Class 3. Full traceability — by serial number, by lot, by component date code — is standard on the shops we shortlist for regulated industries. We match each program to a shop with the right mix of electrical, mechanical, and test capability, sized for your volume so you're not paying enterprise overhead on a 50-unit run.
Why San Antonio teams source box build through SmartFab
One RFQ, one accountable partner
One box build RFQ from San Antonio 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 San Antonio box build program so your team ships product instead of chasing shops.
Better supplier fit
Box build is where electrical, mechanical, and test capability all have to live under one roof — and the right shop depends on which of those dominates. For San Antonio programs in defense, that means placing the build on a line with the right certifications and volume profile from day one.
Build approach for San Antonio box build programs
When we route a box build RFQ for a San Antonio customer, we evaluate the build against facilities in our network on three axes: certifications (does it need ISO 9001 with ISO 13485 or AS9100 add-ons?), volume (prototype, low-volume, production), and lead time. San Antonio's defense (Lackland, BAMC) and growing med-device base needs ITAR and ISO 13485 partners — our Texas bench covers both with domestic capacity.
For defense programs in San Antonio, we typically return one accountable manufacturing quote within 24–48 hours.
