Hi Ken,
As they say in the movies: "here is my 2 cents".
IPC-610C, Section 11.2.3, last paragraph prohibits
wires, or staking tape, or adhesive from overhanging
the edge of the PCB. Thus, running a wire from one
side of a PCB to the other, (over the edge) will
violate this section.
I understand the update of IPC-7721 will have a
section on jumper wires that explains how to use
"non-used" plated through holes for routing wires from
one side to the other. And the update will also
document a method for drilling and sleeving a hole for
the same purpose. (We use these techniques
occasionally.)
You can find these documented procedures at the
circuittechctr.com, web site. The procedures are in
our "guides" section (bottom of home page), section
6.
I agree with Ed Valentine, if you have a unused
through pin or lead, use it. If I were going to use
a unused lead on a DIP, I'd isolate it from the
component first.
I have no experience using an "edge clip".
I'll be interested to know how you solve your dilemma.
thanx
Bill
