The board would be a very small single sided pcb about the size of a postage
stamp.  If all smt is used the weight would only be a few 10's of grams. I was
assuming all the components would have been mounted on the "up" side so
any force would push the parts onto the board.

I posted the question onto another list and one of the fellows there evidently
designed something along the same use to detonate firework shells. Those get
fired off from a mortar which would have a more abrupt kick than what these 
would..
I couldn't see anything producing enough G to peel off the copper.
