5.1 Thermal and Soldering Information
Best thermal performance is acheived when slug is soldered to PCB.
It is recomended to have five solder dots (See fig. 28) without resist to connect the Copper slug to the
ground layer on the soldering side. Moreover it is recomeded to connect the ground layer on the soldering
side to another ground layer on the opposite side with 15 to 20 vias.
It is suggested to not use the PCB surface below the slug area to interconnect any pin except groung pins.
