Mechanical Description
The Generation V of Add-A-pak module combine the
excellent thermal performance obtained by the usage
of Direct Bonded Copper substrate with superior
mechanical ruggedness, thanks to the insertion of a
solid Copper baseplate at the bottom side of the device.
The Cu baseplate allow an easier mounting on the
majority of heatsink with increased tolerance of surface
roughness and improve thermal spread.
The Generation V of AAP module is manufactured
without hard mold, eliminating in this way any possible
direct stress on the leads.
