Conducting space projects has its own characteristics, which often go far beyond the boundaries of designing boards and circuits. In a review article, the author briefly introduces the reader to aspects specific to the development of electronics in the space industry.
Pewter Mustache and Protective Cover
Let's start with the unusual. The author has no doubt that all the developers of ultra-reliable systems familiar phenomenon called "tin whiskers» ( tin whiskers ) - long thin crystals of yarns that can grow out of the surfaces of chips or solder terminals.
They grow quite quickly, so much so that after months, these whiskers can simply close adjacent leads. One of the options for neutralizing this process is the application of a certain protective coating, the choice of which is nontrivial.
