Suitability of IC packages for wave, reflow and dipping 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. For SDIP packages, the longitudinal axis must be parallel to the transport direction of the printed-circuit board.
4. These packages are not suitable for wave soldering. On versions with the heatsink on the bottom side, the solder
5. If wave soldering is considered, then the package must be placed at a 45 angle to the solder wave direction.
6. Wave soldering is suitable for LQFP, QFP and TQFP packages with a pitch (e) larger than 0.8 mm; it is definitely not
7. Wave soldering is suitable for SSOP and TSSOP packages with a pitch (e) equal to or larger than 0.65 mm; it is
