Radiation degrades EEE components and generates device perturbations that could lead to its malfunction or destruction. These effects are highly dependent on the radiation type: gamma radiation, heavy ions, protons, etc., but also on the device technology, the manufacturing lot...
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 burgeoning demand for the incorporation of disruptive technologies into space industry clearly requires fast and reliable procedures for the space qualification of these innovative components. This also entails a close collaboration between the manufacturing and...
This technique combines to two inspection methods (microscopy and fluorescent dye penetrant inspection) commonly used for the detection of surface anomalies such as cracks, porosity, laps, delaminations, and other discontinuities. This joint approach is intended to highlight and...
Microwave Laboratory Experts in design, packaging and testing of high reliability components Engineering Expertise The experience and technical knowledge achieved by our engineers in the last years is major lack for most space and harsh environment companies. Our engineering...
