... Notes 1. For more detailed information on the BGA packages refer to the “(LF)BGA Application Note” (AN01026); order a copy from your NXP 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 “ ...
