Relays are one of electronics mechanical devices, and they are used for various purposes. So relays are demand for high reliability under various conditions. Especially, Sealing relays are packaged with sealant to prevent from invasion of solder-flux, foreign matters, corrosive gas, etc. Adhesive property between adhesives and metallic terminals, base or case made from plastics affects reliability of relays. Sealing relays can classify two types according to soldering method. One is Surface Mount type. Another is Through Hole type. Especially, Surface Mount type relays are revealed that sealing reliability in soldering is deteriorated by humidity. We paid attention to the fact that the break points of sealing in soldering caused by humidity are near the interface between sealing agents and plastics. And we studied about effects of humidity for the interface between sealing agents and plastics. As a result, we revealed that the cohesive force in Liquid Crystal Polymer used as relay-case is deteriorated by humidity, and the deterioration of the cohesive force in Liquid Crystal Polymer caused the deterioration of sealing property in soldering. |
