Burn-in chamber for sensor screening
An ideal burn-in chamber for screening of sensors that make up reliable ADAS
With advances in automated driving and ADAS, sensors are becoming ever more important as safety features. There are various types of sensors mounted on cars for detecting people and lanes, accelerator pedal sensors, and power steering sensors. This chamber inputs a signal in a high-temperature environment to activate the sensor, then monitors the output to determine the quality.
Test category
- High-temperature screening test
- Low temperature test
Test devices
- Accelerator pedal sensor
- Power steering sensor
- CMOS sensors
Keywords
- ADAS
- Sensors
- Aging
POINT 01Efficient screening
- Monitors the output voltage from automotive sensors for each channel to determine the quality.
- The temperature program and test conditions can be synchronized during testing.
POINT 02Automatic insertion/extraction mechanism
The chamber is equipped with an automatic insertion/extraction mechanism that can insert multiple burn-in board card edge connectors at once, allowing for streamlined burn-in testing.
