As more IC components are used in cars which increase the complexity of the automotive electronic system, the BLR has gradually become one of the important test items of automotive electronics. Tier 1 module makers including BOSCH, Continental, and TRW are releasing “Board Level” specifications covering combined vibration test, temperature cycling and shock test, and shock test. More strikingly, the AEC has also come up with the latest AEC-Q104 qualification to clearly define the test items of BLR.
Although AEC-Q104 defines the need for testing automotive electronics BLR, it only provides guidelines for individual components in tests such as Temperature Cycling (TCT), Drop, Low Temperature Storage Life (LTSL), and Start Up & Temperature Steps (STEP). It wasn’t until the introduction of AEC-Q007 in March 2024 that a comprehensive standard was established, combining components and printed circuit boards (PCBs) to address the popular automotive board-level reliability testing requirements.
Based on long-term observations and experience, iST’s reliability testing laboratory has noted that electronic components can indeed exhibit anomalies under prolonged temperature conditions. Compared to consumer-grade components, automotive components must overcome more temperature-related factors due to the critical importance of user safety. Therefore, the reliability of automotive components must be treated with even greater rigor.
