you might be right but the real world is where things really matter as most the are involved in higher education and high level engineering tend to work in isolated none real world environments where millions of dollars of equipment and controlled environments are their workspace.
the real world which is unfortunately based on cashola tend to cut corners to reduce cost but end up with products out in the field that may eventually fail sooner as compared to things from days gone by where quality ruled rather then quantity.
its not that i don't understand your opinion or even think that your wrong i just no if somethings within reason manufacturers will release the product and in the end in most cases the enduser takes it.
Ps3-4, xbox260-new one, tons of different laptops and the list goes on and on, and even tho because of bad flow profiles not really corrected to the none lead based solder has lead to tons of graphix failures occuring before they really should have. and a large part of those actually aren't even related to bad soldering but because Nvidea decided to let the graphix chips go out into the real world when they should not have.
in Nvidea's case the real issue lays not with board level bga mount but with bad flip-chip manufacturing which was a ENGINEERED calculation prior to packaging the wafer inside the outter bonded bga carrier. People think that reheating the board/bga mount is fixing the problem when all they are really doing is overheating the bga package which is making the flip-chip connections temporarily reconnect inside the chip itself.
as i said i understand your concern but i honestly think that until people that actually own and use the board start to complain about heat related issues i think you should do yourself a favor and let the issue go as i hate when i see unending debates over unproven issues and over the years i have watched you contribute since you 1st appeared over on Freaktab doing the linux thing along time ago and would never want to see people loose respect or credibility over something like this, especially when you've earned somuch cred's over the years by helping others.
