Connie,
Are there any other locations in the circuit away from the lead
where this part could be tapped in? Or possibly it must be there at the
pin for other reasons? If it has to be there, this would be considered
as a jumper wire as outlined in 11.2.5.2, which makes no mention of
solder touching the body. Though not good standard practice, many rework
scenarios are unique to an assembly and do not fall under 'cookie
cutter' assembly techniques. Explain to your customer the issue this
particular rework raises in regards to workmanship standards, gain their
understanding and approval, and move forward.

Subject: [TN] IPC 610 Interpretation
Good afternoon all,
We have a rework situation in our facility. Here goes:
We have a gull wing component that we have to add a large
through-hole capacitor lead on to one of the IC leads. Per the 610
requirement, 12.2.5.5, solder may not touch the body of the component of
a gull wing component. Because this is not a normal build situation, is
that a requirement that has to be met? It is very difficult to solder
this large lead on to this small lead, making a solid connection,
without getting solder between the lead and body of the IC. I realize
the 610 is a guideline for us to make decisions.
So......... In your opinion, what would you do? Rework, accept
as is, .....
I realize the final decision is between us and our customer, but
would
like to hear what others think aobut this.
Thanks,
Connie M. Korth
