dig deeper Ben
some of these can be calculated
what will be the temp offset from one side to the other of C110 Cu with a hot side temp of 40°C and a thickness of:
0.075" ?
0.150" ?
0.300" ?
(there are wbs with these actual thicknesses)
assume bp same size as die, no edge effects, uniform heat flux
- finished ?
now go to waterloo and play with some more realistic assumptions
go to the AS site and see how Nevin looks at the issue
(though I have difficulties with some of it)
an aside: you cannot start each thread as if it were a brand new world, at some point you have to start incorporating what has gone before into your 'body of knowledge'; this is basic matls sci stuff - on google, all over
and the same applies to the thermo stuff, we're tilling the same field over, and over, and over; identify the principles involved - and apply them to each 'new' issue
and I repeat, read Cathar's thread; and re-read it until you understand the PROCESS by which he made choices
