... Philips Semiconductors 8.1 Alarm function modes By clearing the MSB of one or more of the alarm registers (bit AE = alarm enable), the corresponding alarm condition(s) will be active. In this way an alarm can be generated from once per minute up to once per week. The alarm condition sets the Alarm Flag (AF). The asserted AF can be used to generate an interrupt (INT). ...

A more in-depth account of soldering ICs can be found in our Data Handbook IC26; Integrated Circuit Packages (document order number 9398 652 90011). There is no soldering method that is ideal for all surface mount IC packages. Wave soldering can still be used for certain surface mount ICs, but it is not suitable for fi ...

... SSOP, TSSOP, VSO, VSSOP For more detailed information on the BGA packages refer to the (LF)BGA Application Note [1] (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 Data Handbook IC26 ...
