Frozen82540.jpg

A picture is worth a thousand words, and in a blog that's a great time saver!  These are unaltered (except for size) images taking during our testing for our industrial temperature run for the 82540EP. The chip is marked as an EM for test reasons. The 82450EP is just like the 82551IT and the 82574IT in that it supports temperatures of +85/-40. The snippet on the left is the card at -85 degrees Celsius.  The ice is from the humidity.  The ice would melt off near the edges and it pooled on the motherboard and finally caused the motherboard to short out.  The right part of the image is running at 166 degrees Celsius and it was transmitting data until the solder melted.  If you look closely at the white lines around the top right corner and the bottom right corner you can see that the part is actually shifting clockwise and down as the balls of solder melt.  The capacitor at C39 has actually melted off and the force of the heater has blown it off the board.  The silver trail is the capacitor solder.  The orange line is the temperature probe.

This is just some of the testing we do to make sure that our products are well tested. 

     Now for a couple statements that our lawyers want to make sure you’re aware of.  First, just because we test to +166/-85 doesn't mean you should try to use it there.  Second, if you put the parts into an environment that is higher than the supported temperature, it will invalidate your warranty not to mention your product and Intel isn't responsible for any damage done.

 

 

Hopefully I'll have more cool pictures for you in the future.

 

 

Review time!

1)  Intel offers industrial temperature parts

2)  Testing until failure often leads to cool pictures

3)  Thanks for your interest in Intel networking products.
