Based on JEDEC JESD51-7, defining the PCB as 4 layer 2x 2oz and 2 x 1oz (inner) with copper area 70mm x 70mm. It is used as high conductivity test bed for package thermal performance assessment.
I'm interest in transient and wish to know if anyone calculated or/and measure thermal capacitance (as well as JESD51-3). Is this validated?
You may modify them to include thermal vias (for exposed pad package such as QFN or TSSOP28 or DPAK).
