Hello Edward

How many wires?  As many as the designer, assembler, and customer, will
agree to.  There isn't a spec limit that I'm aware of.  More often it's
a question of cost of installing jumpers vs cost of re-design.
Reliability should not be a big factor, although obviously more hand
assembly leads to more opportunities for error.

All,
I have been tasked with trying to find out if there is a limitation on
the number of jumper wires permitted on a class 3 PCB assembly. I've
looked @ 610 and 7711 and 7721 and can't find anything. I would be
grateful for any direction anyone can give me on this.
Thanks,
