Aging of electronic components refers to the phenomenon that the performance of components gradually declines or changes during long-term use. The main factors that cause the aging of electronic components are as follows:In some cases,Texas InstrumentsThe advantages will become more and more obvious, and it will be able to develop indomitable after market tests. https://www.asourcingelectronics.com/product/detail/store/4507805/tca9517adgkr.html
Temperature effect:
High temperature can accelerate the chemical reaction and physical changes of materials, resulting in the decline of temperature resistance of insulating materials, and the connection points may melt or break.
Temperature cycling can also lead to thermal expansion and contraction, increase mechanical stress, and thus cause fatigue and cracks.
Humidity:
In high humidity environment, moisture can penetrate into the components or solder joints, causing corrosion, short circuit and electrical performance degradation.
Humidity changes can also lead to the performance degradation of insulating materials.
Current and voltage stress:
Excessive current and voltage may lead to overheating and overload of components operating under high load for a long time, thus accelerating the aging of components.
Long-term electrification of DC and AC currents may also lead to problems such as oxidation.
Electromagnetic interference:
The interference of external electromagnetic field may cause signal interference, thus affecting the normal function of components, and long-term exposure to interference environment may lead to the degradation of component performance.
Material fatigue:
Additional stress of components (such as mechanical stress, vibration, etc.) will lead to fatigue of metals and other materials, especially in solder joints and connections.
Chemical corrosion:
The materials of electronic components (such as metals) may react with gases and liquids in the environment, resulting in surface corrosion and affecting electrical conductivity and mechanical strength.
Radiation:
High-energy particles or radiation (such as gamma rays, ultraviolet rays, etc.) will damage semiconductor materials and insulating materials, resulting in performance degradation.
Electrostatic discharge (ESD):
Electrostatic discharge may instantly destroy sensitive components, resulting in functional failure or performance degradation.
Production defects:
In the manufacturing process, there are defects in design, materials or technology, which may lead to premature aging of components under normal use.
Understanding these aging factors can help engineers to take corresponding preventive measures when designing products and improve the reliability and service life of components.
