Ed,
I would be interested in seeing cross-sectional views of the solder joints
made with said connectors.

Subject: [TN] Dewetting on high current connector
Greetings fellow 'netters,
I have discovered a dewetting condition on high current blade connector(s)
which causes me to raise an eyebrow. I can't find any scholarly articles
discussing the long term effect such an irregular surface at the material
contact interface (photo located at
http://stevezeva.homestead.com/Terminal_de-wetting.JPG ) will have on
connection integrity at high current. This is an extreme environment
automotive application with MTBF expectations in excess of 10 years.
Any guidance and/or professional opinions would be greatly appreciated.
As always, thanks to Steve G. for sharing his webspace with us!
