chip operating temperatures`

[talltom]

   I'm going to take BOTH sides on this one! Generally I don't see to much 
problems with pcb's, except in cars. One of my customers has an electronics
co that has about 8000 ft of pcb's, and little problem with pcb's. On the 
other hand, I'm certain we could come up with a few rooms full of auto pcb's
with cracked traces, specifically Mercedes temp control. I don't know what
MBZ used for a substrate, but do know that the usual fix is to eyeball for 
and solder up cracks in trace.(Mine is mechanical, thank you)
    One thing I've never seen is the failure of the printed circuits on the 
what appears to be some type of mylar used in many dash assembly's. Anybody
know what the material is? And the difference in expansion rate between it 
and copper? I'm guessing that either the expansion rate is similar or copper 
exapnds more than the film, or I'm full of it.
