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.
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.
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.
