Hello,
    I am using a Su8 coating over a permalloy core as an insulating
material. My sensor is subjected to a temperature variation of about -20 deg
C to + 50 deg C . Can anybody help me regarding the effect that the Su8 will
have on the core , i.e. will there be any contraction or expansion of su8 at
the low and high temperatures and whether or not it will induce any stress
effect on the core, changing its permeability.

Debashis.
