DC members,
I have note on my assemblies to trim excess pin length. I am wondering if
there is a standards or spec on finished
products (assemblies) that outlines this topic? I don't believe it is
covered in the J standard.

I have the documentation (IPC-D-325A) for PCB assemblies and support
drawings.
There has been something that I think needs addressed on the PCB assembly
section; Wires and their connection.
Here are the topics of concern;
Where a wire is connected to a PCB, should it always be noted and what is an
appropriate Ref Desg?
What sort of wiring table or wire list should be used to display the
connections between a pcb and a connector
or something else? (Granted the opposite connection may be in a higher level
drawing, but not the board connection)
Notes concerning tinning and soldering discrete wire.

This may not be the appropriate place to document this, but is just one of
may assembly issues I come across.
We have (employer) our own way of doing things with no problem, but I like
documentation supporting my work.
(For ISO reasons also)
