Ultra Thin Circuits utilizing Bond-Ply
Heat Spreading Capability
Dielectric thickness and foil thickness both influence heat spreading
capability in Thermal Clad. Heat spreading is one of the most powerful
advantages derived from IMS. By increasing copper conductor thick-
ness, heat spreading increases and brings junction temperature down.
In some cases very heavy copper can be utilized along with bare die
to eliminate the need for a standard packaged component.
The following graphs depict both the thermal impedance value and
case temperature when relating dielectric and foil thickness.
