In Alter Technology micro-sectioning is accomplished in a specifically dedicated laboratory and by ESA certified staff on PCB/SMD inspection. ESA selects those laboratories that according to the higher quality standards are recommended to perform such operations on SMT/PCB...
Plated Through Vias (PTV) are critical elements in PCB systems and special care must be paid during their inspection in order to ensure the reliability, as they are one the main factors that determine the PCB Quality. The functionality and reliability of PTVs are dictated by:...
Thermomechanical stress in PCB/PWBs is generated by the mismatch between the coefficient of thermal expansion (CTE) of the materials comprising the system. In general laminate material used for PCB fabrication, as well as other dielectric polymers, have larger CTE than metal...
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...
Improper degree of compression: Stress relaxation, Improper crimping, Diagnosis tools and Inspection conducted in Alter Technology laboratories.
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 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...
Crimping together with wire wrapping and spring clip systems are the preferred alternatives for the solderless connection of electrical conductors. In particular, crimped connectors offer several advantages such as: Gas-tightness and protection against oxidation and corrosive...
The ESA (European Space Agency) named this satellite as Aeolus, coming from Greek mythology, Eolo (in Greek), is known as the father of the race eolia, the lord and god of the winds. What is intended with this satellite is to gather accurate information about the winds, not...
The satellite SAOCOM 1A, is the first of two identical satellites where it covers the development of active instruments operating in the microwave range. Put into orbit these satellites comes from the Argentine Government. Developed, manufactured and built in the southern...
BepiColombo will provide the best understanding of Mercury to date. It consists of two individuals orbiters, the Mercury Planetary Orbiter (MPO), that will map the planet, and the Mercury Magnetospheric Orbiter (MMO), that will investigate its magnetosphere.
Material Analysis is performed to detect and identify the materials used in the manufacturing of semiconductors and microelectronic parts and packages. One particular use of this analysis is the detection of prohibited materials, especially in the lead finish, to identify...
