Joe,
A couple of obvious things.
1) If you have a customer that wants to disallow this for production, then
he's willing to foot the bill for new board layouts. That's good.
2) If it's on the print, that takes precedence over any general rules or
other edicts. Whether allowed or not, you're obligated to make the parts to
print.
If "dead bugs" are part of "Production", gosh, I hope the order is very
small. "Dead Bugs" should be limited to development maybe even prototype
work. Otherwise, new board layout is needed.
You might want to know why they're suggesting this? I'd be curious.
Good Luck.

Subject: [TN] Dead Bugs
We've talked before about implementing design changes with "dead
bug" components, where you turn the part upside down, bond
it to the board surface, and solder wires to the pins.
Of course, this takes more labor, but sometimes it's useful to
implement a change for a short time while artwork is being updated.
Now we have a customer talking about disallowing this practice for
production. Anyone have a good reason why dead bugs should be
outlawed? Are there any specs that prohibit this?
