Visualizing the reliability evaluation of automotive electronic components in a "high-temperature environment"
Do you encounter any of these issues when evaluating automotive electronic components?
- Want to know the temperature of parts in real time during high-temperature testing
- Contact sensors cannot detect temperature distribution
- Visualizing the heat generation status inside a thermostatic chamber
- I want to obtain evaluation data that meets AEC standard testing requirements.
When evaluating the reliability of automotive electronic components, it is important to detect heat generation behavior and hot spots in high-temperature environments.
thermal image measurement, which can measure temperature distribution over a wide range without contact, contribute greatly to the efficiency of quality evaluation.
Solution Overview
Heat-resistant thermal image measurement CPA-L25HT
The CPA-L25HT is a heat-resistant thermal image measurement that can be installed and used inside a thermostatic chamber.
Main features
- Temperature measurement range: 0 to 300°C
- Ambient temperature: Maximum 200°C (when using a heat-resistant case)
- Resolution: 320 x 240 pixel
- high-speed frame rate up to 60Hz
High-resolution thermal images allow for real-time visualization of minute temperature distribution and instantaneous heat generation in electronic components.
Three scenarios where you can see the benefits of implementing the system
① Evaluation of electronic components in a high-temperature thermostatic chamber
By placing it in a temperature chamber, it is possible to measure the temperature distribution in real time when parts are exposed to a high-temperature environment.
It enables temperature distribution analyzing across the entire surface, which is difficult to do with contact sensors.
② Reliability evaluation through heat generation analyzing
high-speed frame rate of 60Hz enables continuous recording of the transient heat generation behavior of electronic components.
By analyzing time changes
- Temperature rising trend
- Timing of abnormal fever occurrence
- Hotspot Location
You can understand the following:
③ Aluminum electrolytic capacitor reverse voltage test
In reverse voltage testing, changes in temperature distribution after energization is applied can be visualized in real time.
for example
- Fever distribution after 1 minute
- Temperature diffusion after 5 minutes
- Maximum Temperature Rise
Recording these will help you analyzing the heat generation origin and degradation mechanism.
