Actually, crimping properly done does not need soldering.  Properly
done is the hard part.  There is some serious materials science to
know.

As I pointed out earlier:

(1)
A properly done crimp never fails.

(2)
If it never fails it is properly done.

I need a way to tell the proper ones from the nonproper ones that
doesn't involve waiting for them to fail.  I need a procedure that
leads to no failures.

Without soldering the crimp lugs, I had neither.

I find myself in the same position with some SE Asian suppliers.

You can specify on paper till you're blue in the face, but they'll
still make substitutes to reduce cost in the initial evaluation
stages. If you catch these early, and detect potential trouble, I find
that the resulting product will generally tow the line in production
shipments.

I have no problem with modifying drawings, adding alternates to
reflect the source's capability, providing the product proves
functional and accurate info on the subs made is provided for the
docs, prior to finalizing the sale. This is normally needed for safety
documentation accuracy, anyways.

Maybe next time, eh?

Since we are talking about evaluating alternates, I believe it should
be "toe the line".

That alternative does not always result in timely completion of a
project, within budget. Intelligent flexibility, properly supervised
and documented, can be a profitable characteristic of part sourcing
activity.

These guys are simply trying to do their job - if you can help them
succeed, it can only contribute to your own success.
