Suitability of surface mount IC packages for wave and reflow soldering methods
Notes
1. For more detailed information on the BGA packages refer to the “(LF)BGA Application Note ” (AN01026); order a copy
2. All surface mount (SMD) packages are moisture sensitive. Depending upon the moisture content, the maximum
3. These packages are not suitable for wave soldering. On versions with the heatsink on the bottom side, the solder
4. If wave soldering is considered, then the package must be placed at a 45 angle to the solder wave direction.
5. Wave soldering is suitable for LQFP, TQFP and QFP packages with a pitch (e) larger than 0.8 mm; it is definitely not
6. Wave soldering is suitable for SSOP and TSSOP packages with a pitch (e) equal to or larger than 0.65 mm; it is
