As such it includes three main sections. The first consists of two major state-of the-art reviews, and two invited introductory papers. The reviews were prepare978-94-010-6868-0978-94-009-0847-5许可 发表于 2025-3-31 03:03:23

iability to accidental or repeated drop events. Impact drop test and solder joint reliability investigations for Pb-based and Pb-free soldered assemblies were investigated. Explicit dynamic FEA modeling and simulation of the board-level drop test were used to predict the transient vibration deformatDIKE 发表于 2025-3-31 10:29:49

The lower intersection of discordia with concordia represents the time of the episodic event and the upper intersection represents the age of the phase. . (1957) suggested that diffusion of lead out of a phase might take place at a constant rate
