What is Electrochemical Migration
Electrochemical migration is a phenomenon that occurs when an electric potential is applied across a conductive path on a printed wiring board, and moisture and ionic contaminants are present. The electric field causes the ions to migrate along the conductive path, forming metallic filaments or dendrites that can bridge adjacent conductors and cause short circuits or corrosion.
Electrochemical migration can affect the reliability and performance of printed wiring boards and assemblies, especially in high-density, low-voltage, and high-humidity applications. Some of the factors that can influence electrochemical migration are:
The type and amount of ionic contaminants on the board surface or in the solder mask
The level of humidity and temperature in the operating environment
The spacing and geometry of the conductors
The magnitude and polarity of the applied voltage
The duration and frequency of the power cycles
What is Solid State Electromigration
Solid state electromigration is another phenomenon that occurs when an electric current flows through a metallic conductor on a printed wiring board, and causes the atoms to move from regions of high electron density to regions of low electron density. This can result in voids or hillocks formation in the conductor, which can lead to open circuits or increased resistance.
Solid state electromigration can affect the reliability and performance of printed wiring boards and assemblies, especially in high-current, high-temperature, and fine-pitch applications. Some of the factors that can influence solid state electromigration are:
The type and composition of the metallic conductor
The level of temperature and current density in the operating condition
The direction and polarity of the current flow
The mechanical stress and strain on the conductor
The presence of intermetallic compounds or grain boundaries in the conductor 061ffe29dd
