Turnkey Box Build Solutions for Complete Products
From mechanical assembly and PCB integration to harness routing, testing, labeling, and packaging— JINST delivers shipment-ready units built to your work instructions and quality standards.
Enclosures, PCBs and harnesses built and tested as one complete system.
One team owns assembly, testing and pack-out for shipment-ready units.
What We Do
Our box build services bring together mechanical, electrical and test operations into one smooth workflow. You ship us components or sub-assemblies, and we return fully built, tested and packed units.
We support new product introductions, engineering builds and ongoing production with clear work instructions, controlled change management and reliable delivery.
Every unit passes defined test gates.
From kitting to final packaging.
Complete Assembly Process
From metalwork and PCBs to fully tested, labelled and packed units—one integrated flow.
