4 . Final test & configuration
The final test and configuration stage is the last verification step before shipment. Relying solely on human visual observation introduces unacceptable risk; testing procedures must be automated, repeatable, and data-driven.
This chapter configures the architecture of system-level validation. Requirements for building automated
- 4.1 Functional testing
Functional Testing (FCT) serves as the final quality gate. It verifies that the completed Box Build unit meets specified engineering performance criteria. Unlike basic continuity or Hi-Pot checks, FCT...
- 4.2 Safety testing
Safety testing is a mandatory step within the final assembly process, verifying that the product poses zero electrical hazard to the end user. These tests confirm that the enclosure, grounding scheme,...
- 4.3 Firmware loading and device programming
Firmware loading and device provisioning install the embedded code, set unique identifiers (like MAC addresses), and configure calibration tables. Loading the correct firmware revision and properly lo...
- 4.4 Calibration and adjustment
Calibration and adjustment are final assembly steps that ensure a product's functional parameters narrow down to meet specified engineering tolerance limits. In physical assemblies, individual compone...
- 4.5 Environmental and burn-in testing
Environmental Burn-In Testing is an accelerated aging process applied to fully assembled electronic systems. The process induces failure in marginal components prior to shipment. For high-reliability...
