... Heat Sinking the thermally conductive material such as copper or aluminum. The slug should be at least the same RMBA19500A-58 thickness as the PWB. In the case of the heat sink, a small pedestal should protrude through a hole in the PWB where the package bottom is directly soldered. In either configuration, the top surface of the slug or the pedestal should be made coplanar with the package lead mounting plane i.e., the top surface of the PWB. Use Sn96 solder (96.5% Sn and 3.5% Ag) at 220º ...
