Please respond
to Brian Ellis
Sorry, still not good enough. What kind of vacuum package? How thick?
How sealed? What vacuum? What conditions of storage? What component
construction? What finish? How clean? How do you define
reliability/functionality? What figure of confidence level? How long is
a piece of string?
