In this study, the interfacial reactions and mechanical properties of solder joints after multiple reflows were observed to evaluate the applicability of the developed materials for high-temperature soldering for automotive electronic components. The microstructural changes and mechanical properties of Sn-Cu solders regarding Al(Si) addition and the number of reflows were investigated to determine their reliability under high heat and strong vibrations. Using differential scanning calorimetry, the melting points were measured to be approximately 227, 230, and 231 °C for the SC07 solder, SC-0.01Al(Si), and SC-0.03Al(Si), respectively. The cross-sectional analysis results showed that the total intermetallic compounds (IMCs) of the SC-0.03Al(Si) solder grew the least after the as-reflow, as well as after 10 reflows. Electron probe microanalysis and transmission electron microscopy revealed that the Al-Cu and Cu-Al-Sn IMCs were present inside the solders, and their amounts increased with increasing Al(Si) content. In addition, the Cu6Sn5 IMCs inside the solder became more finely distributed with increasing Al(Si) content. The Sn-0.5Cu-0.03Al(Si) solder exhibited the highest shear strength at the beginning and after 10 reflows, and ductile fracturing was observed in all three solders. This study will facilitate the future application of lead-free solders, such as an Sn-Cu-Al(Si) solder, in automotive electrical components.

with the rapid development of information technology, the deepening of sensing detection and automobile electronic technology, the safety and reliability of vehicle electronic control has been the core problem to be solved in the automotive electronic control system. Sensor detection technology has become an important part of the development of automotive technology. This paper first analyzes the automobile electronic detection technology and sensing detection applications. Based on this, the theoretical framework principle model of automotive electronic software program design has been further deepened, so as to take the electronic program design of automotive anti-collision radar as the empirical analysis example. Finally, the optimization of automotive electronic program software design provides scientific basis and practice way to a certain extent in this field research.

EAST-ADL is an Architecture Description Language (ADL) initially defined in several European-funded research projects and aligned with AUTOSAR and ISO26262. It provides a comprehensive approach for defining automotive electronic systems through an information model that captures engineering information in a standardized form. Aspects covered include vehicle features, requirements, analysis functions, software and hardware components and communication. The representation of the system's implementation is not defined in EAST-ADL itself but by AUTOSAR. However, traceability is supported from EAST-ADL's lower abstraction levels to the implementation level elements in AUTOSAR. In this article the authors describe EAST-ADL in detail, show how it relates to AUTOSAR as well as other significant automotive standards and present recent research work on using and advancing EAST-ADL, the functional safety standard ISO 26262, heterogeneous multi / many core architectures, security and for multi-objective optimization.
