As typical length in integrated circuits decreases thermal management is becoming a key factor determining the reliability and lifetime of such systems. Furthermore, micrometric and submicrometric objects in integrated circuits modify local heat transport and may lead to the formation of unintentional hot-spots. Thus, the accurate measurement of the local temperature with micrometric spatial resolution is crucial to confirm the suitable operation of highly integrated systems.
Different types of Corrosion / Contamination in Crimped Connectors

Crimped connectors are gas-tight junctions ideally protected against environmental contaminants and corrosive agents. Nonetheless inappropriate crimping and inherent connector and wire defects reduce this protection. Thus, depending of the storage atmosphere, non-conducting corrosion products can be formed, or stress corrosion cracking can be eventually induced. The former act as insolation layer that reduces the connector conductivity and both corrosion effects are identified as critical factors involved in common fails reported for electrical connectors.

High reliability assembled PCB prototypes as well as novel surface mounted devices (SMD) and mixed systems must be assessed according to well defined qualification test plans. Such high reliability verification programmes are not limited to just evaluate the robustness, reliability and performance of the product but they also address the verification of tools, fabrication procedures and involved materials, as well as the confirmation of product integrity. For instance, ECSS (European Cooperation for Space Standardization” (ECSS) standards used in space programs
