A product’s electronics work correctly on the test bench. Its firmware performs as expected. The mechanical parts fit, and each subsystem appears to have passed its tests.
Then everything is installed inside the final enclosure, and new problems suddenly emerge.
This is where product integration becomes critical. Bringing the electronics, firmware, power system, wiring, mechanical components, and enclosure together creates a very different operating environment. Heat accumulates, airflow changes, components may interfere with one another, clearances become tighter, and access for debugging can disappear.
In this episode of China Manufacturing Decoded, Adrian is joined by Paul Adams from Agilian Technology to explain why individually successful subsystems can fail once they are combined into a complete product.
They discuss the importance of staged integration, retaining access to test points, testing thermal and EMC risks early, and validating the product as its eventual users will experience it. Paul also shares a practical five-step framework for moving from successful bench tests to a safe, reliable, and genuinely usable finished product.
