Subject: Long term storage of electronics
Message:
I have a question about electronics in general and circuit boards in particular. Is there research done about how long it is possible to store electronic devices? Does anything happen if you store a cicuit for more than 20 years or is there a good chanse that everything works allright even after so many years. Is there any actions to take during storage to decrease the risk of failure? Thanks for any help on the subject! /Per

I don´t understand if ground active to ground passive means that the stuff simply is not used or if it is put in a store with controlled environment? /Per
