1. All surface mount (SMD) packages are moisture sensitive. Depending upon the moisture content, the maximum
2. These packages are not suitable for wave soldering. On versions with the heatsink on the bottom side, the solder
3. If wave soldering is considered, then the package must be placed at a 45 angle to the solder wave direction.
4. Wave soldering is only suitable for LQFP, TQFP and QFP packages with a pitch (e) equal to or larger than 0.8 mm;
5. Wave soldering is only suitable for SSOP and TSSOP packages with a pitch (e) equal to or larger than 0.65 mm; it is
