| Abstract(J) | 電子部品には偶発故障があり，故障後に電流が継続的に通電されると異常加熱を起こす．車載ECUは他用途ECUに比べて，高温環境下のより厳しい条件で使用されるため，異常加熱の要因検証，対策設計の効果確認が必要である．本研究では，導入コストの高い恒温槽を使わない高温環境の簡易評価構築手法を提案する． Translation |
| Abstract(E) | Electronic components can suffer random failures, and if current continues to flow after such a failure, abnormal heating can occur. Because automotive ECUs are used under more severe high-temperature conditions than ECUs for other applications, it is necessary to investigate the causes of such abnormal heating and to verify the effectiveness of countermeasure designs. This study proposes a method for constructing a simple high-temperature evaluation setup that does not require the use of costly temperature-controlled chambers. |
