Someone had questions about this issue, forgot what man. However found old paper with a considerably interesting theory:
a) Large voids in bond line >>>reduced thermal conductivity
b) Moderate voids " >>>good thermal conductivity, little mechanical stress, no cracks
c) No voids at all " >>>good thermal conductivity, high stress, cracks
So, perfectionism may also be a disaster, read article in Solid State Techn May 1993 p43 etc.
