Ja Saab lavede en Layland / Jaguar fejl.
Jag. monterede deres tændings-elektronik på indsugningen af deres V12.
Det blev varmt ved bykørsel. Det var super velkendt at det gav problemer.
Og så monterer Saab elektronik direkte oven på topstykket..
De kunne have ladet spolerne sidde I enheden på topstykket og trukket elektronikken væk, for der sidder elektroniske komponenter i epoxyen inde i DI kasetten.
Så ja, jeg køber en ny SEM DI enhed og lader den ekstra blive i bagagerummet.
Det er fuld velkendt at elektronik fejler med stigende temperatur: MTBF falder..
Mean Time Between Failures (MTBF) for electronic components is significantly impacted by temperature. Higher temperatures generally lead to a decrease in MTBF, meaning the component is expected to fail more frequently. This is because higher temperatures accelerate the rate of chemical reactions and physical degradation within the electronic components.
Here's a more detailed explanation:
Temperature and Failure Rate:
A common rule of thumb is that for every 10°C increase in temperature, the failure rate of electronic components can double.
Arrhenius Equation:
The relationship between temperature and failure rate is often modeled using the Arrhenius equation, which is a mathematical equation that describes how the rate of a chemical reaction (in this case, a failure mechanism) changes with temperature.
Manufacturer Data:
Manufacturers often specify MTBF values for their electronic components, and these values are typically based on operation at a standard temperature, such as 25°C. When operating at higher temperatures, the MTBF will be lower than the specified value.
Practical Implications:
Understanding the impact of temperature on MTBF is crucial for designing reliable electronic systems. Engineers need to consider the operating environment and its temperature when selecting components and designing cooling solutions to ensure the desired level of reliability.
In essence, the temperature at which an electronic component operates is a critical factor in determining its expected lifespan and reliability. Higher temperatures mean a shorter expected lifespan and more frequent failures.
