Hello all,
Maybe somebody can give me a hint or direct me to any ressources about this
topic.
On a PCB there are a lot of mechanical and electrical parameters more or
less dependent on temperature.
I found a lot of ressouces discussing dependencies of material properties.
What I would be interested in is
the overall dependency of the signal flight time on temperature. The
different temp dependencies might have
different effects on flight time, and might compensate or worsen each other.
- Does anybody know how much effect a temp change for e. g. 0C to 100C I
would have to consider for signal flight
time ?
- What would be the main contributor to this change ?
- Or is the effect not even measerable at all ?
Thanks a lot
