Notes

1. For more detailed information on the BGA packages refer to the â(LF)BGA Application Noteâ (AN01026); order a copy

from your Philips Semiconductors sales office.

2. All surface mount (SMD) packages are moisture sensitive. Depending upon the moisture content, the maximum

temperature (with respect to time) and body size of the package, there is a risk that internal or external package

cracks may occur due to vaporization of the moisture in them (the so called popcorn effect). For details, refer to the

Drypack information in the âData Handbook IC26; Integrated Circuit Packages; Section: Packing Methodsâ.

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

cannot penetrate between the printed-circuit board and the heatsink. On versions with the heatsink on the top side,

the solder might be deposited on the heatsink surface.

5. If wave soldering is considered, then the package must be placed at a 45Â° angle to the solder wave direction.

The package footprint must incorporate solder thieves downstream and at the side corners.

6. Wave soldering is suitable for LQFP, QFP and TQFP packages with a pitch (e) larger than 0.8 mm; it is definitely not

suitable for packages with a pitch (e) equal to or smaller than 0.65 mm.

7. Wave soldering is suitable for SSOP, TSSOP, VSO and VSSOP packages with a pitch (e) equal to or larger than

0.65 mm; it is definitely not suitable for packages with a pitch (e) equal to or smaller than 0.5 mm.
