ADVANCED TEST SYSTEMS
Automated Hot Run-In Test System for Complex ECU Assemblies
At IMI, we engineer advanced, automated test solutions to ensure the reliability and performance of complex electronic control units (ECUs). Our Hot Run-In (HRI) Test System is designed to meet the rigorous demands of high-reliability industries such as automotive, medical and industrial electronics.
Key Features of the MX R13 HRI Station:
High-Capacity Thermal Testing:
The system features 10 thermally insulated towers, each with 9 chambers capable of testing up to 36 ECUs simultaneously under high-temperature conditions.
Self-Heating ECUs:
Each ECU is equipped with power resistors that enable self-heating up to 100°C, simulating real-world thermal stress conditions.
Automated Handling with Robotics:
A high-precision ABB 6-axis robot (150 kg payload) automates the loading and unloading of ECU pallets, ensuring consistent handling and operational efficiency.
Integrated Cooling Process:
After thermal exposure, devices under test (DUTs) are transferred to a dedicated cooling rack to complete the required temperature profile.
Powerful and Scalable Infrastructure:
Each chamber is connected to high-current programmable power supplies (rated at 10kW), ensuring stable and scalable power delivery across all test units.
This system exemplifies IMI’s commitment to engineering excellence, automation, and quality assurance—delivering robust solutions that support our customers’ most demanding reliability requirements.
