silver gull migration

Fulica atra) and silver gull (lat. <]>> These are inherent points of weakness in single-sided printed electronics that increase the risk of silver migration. Unfortunately, the nature of the process and materials can allow pinholes, which still provide avenues for silver migration to propagate. Breeding. Cross-over, bridged or jumper connections are flaws that significantly increases the risk of silver migration — and ultimately circuitry failure — over time. While membrane switch providers have made many advancements since the 1970’s and 1980’s, the majority of suppliers still produce single-sided circuitry, which is constructed with inherent points of weakness that invite unnecessary risk into your application, particularly in harsh environments. Reducing the voltage can also reduce the risk. 0000008317 00000 n Gasketing and sealing technology can stop the ambient penetration of moisture, however, elevated temperatures will make it necessary to utilize other methods to reduce migration. Today, membrane switches operating in harsh environments where moisture and humidity are present are the most vulnerable.
