Mounting Footprint and Procedure: SOLDER PASTE SOLDER PASTE SCREW (2 PLS.) PC BOARD HEATSINK SOLDER FILLED VIA MOUNTING PROCEDURE 1. Drill thermal vias through PCB and fill with solder, such as SN63 type. Dimension given in inches. For best thermal performance the PCB should be placed with thermal joint compound to the heat sink. 2. Solder part in place using SN63 type solder with controlled temperature iron (700°F). 3. To ensure good thermal connectivity to heat sink, drill and tap heatsink and mount PCB board to heat sink using screws.
