Monitoring of JUICE Optical Fibers During Thermal Cycles Keeping the Optical Connectors at Different Stable Cryogenic Temperatures in 3-Chambers Setup Two types of multimode fibers (50µm and 400µm) will be used for the scalar sensor of the JUICE (Jupiter Icy Moon Explorer program) magnetometer. This optical sensor will be placed at the end of a boom. These multimode fibers will transmit modulated laser light through the sensor, the light source, and the detector electronics being located within the spaceship.

Microsectioning sample preparation is an essential tool for the detailed materialographic inspection of EEE parts, including solder joints on PCB systems involving both surface mounting technology (SMT) and through hole technology (THT). In reveals critical information regarding the structural characteristics and the workmanship quality that is not accessible by other techniques.

The manufacture and testing of EEE parts designed for the Space market are complex procedures that strict specification systems have ruled for years. These specifications depend on various factors such us, country of origin of the parts (USA, European, Japan…), use the parts were designed for (Space, Military) and the component’s family (resistors, capacitors, inductors, microcircuits…).

What does Electrothermal events in Crimped Connectors refer to?

Electrothermal events. 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 outgassing processes responsible for organic contamination. Besides the formation of nonconductive layers at the contact interface, high temperature can also cause to the degradation of plastic insulators and contribute to multiple short circuit conditions.
