What's included

Everything between a finished PCBA and a boxed, tested product.

Stop coordinating and start outsourcing. We keep it in one facility, one team, one traceability system.

01 — Mechanical & Plastic Integration

Enclosure assembly, built alongside your electronics

Plastic injection components, enclosure assembly, and mechanical fit integrated directly into the same facility as your PCBA. No coordination between separate vendors, no shipping between factories.

02 — Wire Harnesses & Adhesives

Custom harnesses, robotic adhesive application

Custom wire harness assembly, robotic adhesive dispensing, and conformal coating for boards that need environmental protection, all built to your specification.

03 — Vision-Based Quality Control

Poka-yoke at every station, not spot checks

Vision-based poka-yoke systems at every assembly station prevent errors before they happen. Every unit tracked with photo records, incoming inspection, and test results.

04 — Functional Testing & Final Packaging

Custom fixtures validate every unit before it ships

Custom-built functional test fixtures validate every finished unit. Automated test data recorded per unit, ready for custom packaging to your specification.

Why now

Why companies are moving box build to Mexico.

Rising tariffs on finished electronics products, long lead times, and time zone friction have pushed U.S. hardware companies to rethink Asia based final assembly.

Nearshoring your box build to Mexico cuts logistics from weeks to days, reduces tariff exposure under USMCA, and keeps engineering support in your own time zone, in fluent English, from first article to full production.

Process

How it works, from BOM to finished unit.

1

Send us your BOM and mechanical drawings

Share your bill of materials, enclosure drawings, and assembly documentation. We sign an NDA before any detailed discussion.

2

DFM review in 48 hours

Our engineering team reviews your PCBA and mechanical assembly design, flagging issues before production.

3

First article and pilot run

A complete first article build validates fit, function, and process before we scale.

4

Scaled production, USMCA compliant

Full box build production shipped to the U.S. and Canada under USMCA, with full traceability per unit.
