Protecting electronic components in acidic and basic environments

摘要

Electronic devices (1) protected by an organic polymeric encapsulant (10) and placed in a corrosive environment can have added protection by dispersing in the encapsulant particles of a solid buffer which tend to neutralize the effect of the corrosive agent. This approach is quite effective when strong acids are the corrosive agents, and when solid acid-base buffers are dispersed in the polymeric material. The encapsulant (10) may be elastomeric, and silicone elastomers containing solid acid-base buffers are quite effective in protecting the underlying electronic device (1) from corrosion by strong acids.
