4. Box Build GDP and System Integration
Assembling a PCBA requires microscopic precision; enclosure integration requires systemic control. Box builds introduce complex mechanical tolerances, routing constraints, and human factors.
The System Integration GDP documents torque specifications, cable routing paths, and final functional requirements. It guides mechanical assembly using standardized work instructions, eliminating reliance on operator intuition.
- 4.1 System BOM and Mechanical BOM
A missing $0.02 screw halts a production line just as effectively as a missing $50.00 main processor. While engineering teams obsess over the PCBA Bill of Materials down to the last resistor, the Mech...
- 4.2 Mechanical CAD Package and Drawings
A perfect 3D model does not guarantee a perfect physical part. Manufacturing partners cannot functionally inspect a physical piece of plastic or metal against a digital STEP file without explicit 2D t...
- 4.3 Wiring Harness and Cable Assembly Pack
Cable assemblies are the literal "nervous system" of your product, yet they are frequently the most under-documented, under-specified components in the entire Bill of Materials (BOM). A vague cable dr...
- 4.4 Mechanical Assembly WI: Torque, Sealants, TIM and ESD Controls
The Box Build process is where undocumented knowledge compromises manufacturing consistency. When the assembly sequence relies on an operator remembering which screw goes where, or guessing how much g...
- 4.5 Labels, Serialization, and Regulatory Technical File
A product label is not a graphic design exercise; it is the official legal passport of your product. A perfectly functioning device will be impounded at customs or rejected by distributors if the regu...
- 4.6 System Test, Calibration, and Pack-Out Specification
A Printed Circuit Board Assembly (PCBA) that has passed In-Circuit Testing (ICT) is not a finished product. Mechanical system integration introduces unique, system-level failure modes: pinched custom...
