Multilayer varistors (MLVs)
Standard series
A further advantage of adhesion is that the components are subjected to virtually no temperature
shock at all. The curing temperatures of the adhesives are between 120 ° C and 180 ° C, typical
curing times are between 30 minutes and one hour.
The bending strength of glued chips is, in comparison with that of soldered chips, higher by a fac-
tor of at least 2, as is to be expected due to the elasticity of the glued joints.
The lower conductivity of conductive adhesive may lead to higher contact resistance and thus re-
sult in electrical data different to those of soldered components. Users must pay special attention
to this in RF applications.
