83103Re: [Electronics_101] Ruggedized components?
- Aug 21, 2013When you say "ruggedized", are you talking about fully screened parts as
used in military and space? Or are you talking about general shock
abuse. If it is the prior, yes, there are parts but cost is high and
many commercial products cannot afford the pricing.
If you are talking about the later, then it becomes how the part is
assembled. Some key points:
1. Layout of parts on the board to minimize shock stress and
prevent the parts from coming off. Think about what is shot out of a
cannon / gun. Here if the parts are not in the proper orientation the
parts will break away from the solder joint.
2. Pot the entire assembly, or just the boards. Though it makes
repair difficult, if not impossible (depending on the potting), it does
help keep all the parts on the board.
