Tag - Method ECSS-Q-ST-70-26C Rev1.

The Method ECSS-Q-ST-70-26C Rev.1. is a Standard that defines the technical and quality assurance provisions for the manufacture and verification of high-reliability electronic circuits based a Crimped Connectors.
The Standard defines acceptance and rejection criteria for high-reliability manufacture of surface-mount and nixed-technology circuit assemblies intended to whithstand a normal terrestrial conditions and the vibrational g-loads and environmental imposed by space flight.
The proper tools, correct materials, design and workmanship are included to permit discrimination between proper and improper work.

Failure Mechanics and Causes in Crimped Connectors

by Francisco Javier Aparicio Rebollo

Crimped connectors are extensively present in EEE systems because of the good performance and easier installation at reduced dimension. Due to the key role played, they are required to have high durability even under harsh operating conditions. In the case of unexpected/early...

Corrosion/Contamination in Crimped Connectors

by Francisco Javier Aparicio Rebollo

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...

Electrothermal events in Crimped Connectors

by Francisco Javier Aparicio Rebollo

Electrothermal event refers to abnormal temperature increase leading to malfunction or catastrophic fails. The high temperature reached during such event activates or initiates some of the failure mechanism explained before, such as the growth of insulation oxide layers and...
