Add the NVIDIA problem on HP Pavilion laptop motherboards. GPU BGA's lead
free. I have 3 in my shop to reflow the chips.

Recently, on the Circuits Assembly blog, Dr Ron Lasky published a column,
bragging about the reliability of lead-free electronics - based on the
presentations at a session of SMTAI where he was the chairman. All of these
papers were about commercial electronics, and are well done.
Dr Ron goes on to infer that lead-free electronics should be accepted as
reliable, (in my interpretation) for all environments and situations. Dr Ron
implies that scientists against lead-free are just wrong.
I maintain that the information in this column in Circuits Assembly is very
misleading - regarding harsh environments. I cite the three papers later at
SMTAI from the NASA/DoD participants who each state "lead based assembly
out-performed lead-free in these harsh tests".
Here is the link to the Lasky column:

Please read it, and add your comments if you wish. Should you feel inclined to
drop a note to Circuits Assembly or to Mike Buetow, I am not going to stop you.
Thanks - Denny Fritz
