Finding better methods to lay blame on your customers, no matter how idiotic those customers might be, is an exercise in futility, at best, and a road to lawsuits and lost customers, at worst.

I think that using "weak" parts will not be a viable approach, since your customers can simply claim that your "weak" parts are so weak that they could have been zapped in the factory and shipped with latent failures.
***Indeed, the plan is to test the circuits at the factory just before...
Thank you all for the feedback.
In answer to various posts, yes, this is a design already in the field. In fact it is multiple designs but they all have 5V rails and technicians have a tendency to pick up the boards by their edges, which is coincidentally where most of our ESD damage is...
I am building a couple of simple detector circuits to determine if our board has seen an overvoltage or ESD event. The limiting reagent is that it must be real cheap because it will go onto several thousand boards. And when I say cheap, my boss doesn't want to dole out $1.10 for 15mA fuses...
