If the pins are tempered they should not be trimmed. Also IPC 610 and
J-STD 001 say " should" a recomendation. If they don't cause a problem
in processing. Like catching on the fluxer at wave solder and do not
pose a problem mechanically in the end item you "should not" ( my
recomendation) have to trim. We don't unless specified on the
documentation except where the lenghth causes a problem later.

Subject: [TN] Trimming Leads...
Hi All,
I've got a question about trimming leads on components such as three-row
DIN
connectors, machine pin sockets, PGA devices, things like that...
In the past, I've never trimmed the leads on components like that. But I
can't find any reference that says those are things that you don't lead
clip...
The reason I'm asking is the -610 and J-STD say that for class-3, the
leads
are not supposed to be longer than 1.5mm (.0591"). Should leads be
clipped on
the kind of components I outlined above if they exceed that?
Thanks!!
