Denis,

I find this as an ongoing challenge that is complicated even further by
ourselves. We all have good information and share our experience and ideas
the best that we can, but........

I find that a lot of the time information on what works and what doesn't is
not recorded properly enough to use as data to substantiate our experiences,
and when it is, it's proprietary information and the property of a company
who won't, or can't, publish it's findings for us to use.

If anybody has a solution to this dilemma, please share.

I am convinced that this will not fare well when they try to solder this
part, yet the engineer insists on doing it this way. What argument can I
make, with supporting data, to persuade him? Simply telling him that I know
it is poor practice isn't cutting it! [Adjusting tie..."I tell ya, we get no
