Using direct temperature (vs watts/current/voltage) as input from a heat plate @ 100C - simple conduction - with a disparity of area - Heat plate is 25in sq, as it ratchets down to a 10 mil copper conductor (actually a cupper plated via) through a 100 mil PCB.
Will the temperature rise when it reaches conductor peak (via surface) as opposed to remain steady state?
For the theoretical - resistances are too negligible to factor but if it need a value, the inverse would assume Cu to be 400 w/m-k
So Im trying to solve for for t2
T1=100C.... Along - Dia=.010/Distance = .100 Cu.... With k = 400w/m-k.... T2=( ? )
