i am trained in surface mount as part of my mil-std certification.however the average home user can not repair these boards.not to mention STATIC damage that can lay dormant in a chip and then decide it will shit itself at any time.maybee after two balls of play.this is called latent defective.i hope stern see sense and go back to through hole components,or offer cheap replacement boards.

the cost of a pin these days is not the boards.there is only about $200 worth of board/components,in a machine.
