Assembly Services

Five Services. Eight Industries.
One Precision Standard.

Global Precision Works (GPW) delivers five core electromechanical assembly services — each engineered to take your product from components to a fully tested, shipping-ready unit.

Every product GPW assembles follows the same principle: mechanical structure, electrical components, cabling, and testing come together under one roof, managed by one team, held to one quality standard.

What We Do

Assembly That Combines Mechanical, Electrical, and Cabling into Finished Products

Electromechanical assembly is the process of integrating mechanical structures, electronic components, cable and wire harnesses, and functional testing into a complete, shipping-ready product. Unlike PCBA fabrication — which produces circuit boards — electromechanical assembly takes those boards and all other components and builds them into the final product that ships to your customer.

GPW specializes in this exact scope. We do not fabricate PCBAs. We do not run SMT lines. What we do is receive your bill of materials — the chassis, the boards, the connectors, the cables, the fasteners, the firmware — and assemble it into a finished product that ships from our Monterrey facility tested, labeled, and packaged to your specifications.

The scope spans a wide range of complexity. On one end: a cable harness with 20 terminations. On the other: a multi-rack AI server system with 500+ cables, dozens of PCBAs, thermal management, firmware loading, and 72-hour burn-in validation. GPW handles both ends of this spectrum using the same disciplined process framework: document the build, control the materials, verify at every station, test to specification.

Core Services

Five Core Services — From Component to Complete Product

Each service operates as a standalone capability and as part of a larger integrated build. Most customer programs combine two or more services within a single production line.

Service 01

Box Build Assembly

Complete integration of mechanical, electrical, and electromechanical components into a finished enclosure or housing. GPW receives your components and builds them into a product that is tested, labeled, and ready to ship.

  • Mechanical assembly: chassis mounting, bracket installation, component alignment
  • Electrical integration: PCBA mounting, connector wiring, power supply installation
  • Cable routing and management within the enclosure
  • Firmware loading and configuration
  • Cosmetic inspection and final packaging

Industries served: AI server racks, industrial controls, telecom cabinets, medical device enclosures, energy equipment, appliance sub-assemblies.

Service 04

Testing & Inspection

All quality validation activities performed during and after assembly — from in-process inspection gates to end-of-line functional testing, burn-in, and Hi-Pot testing. Integrated into the production line, not a separate post-assembly step.

  • First article inspection (FAI) on every new program
  • In-process quality gates at critical assembly stations
  • End-of-line functional testing with documented pass/fail criteria
  • Burn-in testing for extended operational validation
  • Hi-Pot testing for electrical safety compliance
  • Full BOM-level component traceability

Industries served: All 8 verticals. Medical devices, aerospace, and AI server racks typically require the most rigorous testing protocols.

Enclosure & Cabinet Assembly

Mechanical construction and integration of housings, racks, cabinets, and chassis that protect and organize electronic and electromechanical components. GPW assembles enclosures and integrates all internal components into a finished unit.

  • Assembly of enclosures, racks, and cabinets from sourced or customer-supplied components
  • DIN rail mounting, panel wiring, and terminal block installation
  • Thermal management integration (fans, heat sinks, airflow routing)
  • Door assemblies, cable entry points, and environmental sealing
  • Labeling, engraving, and cosmetic finishing
