Digital temperature sensor with overtemperature alarms
13.4   Reflow soldering
Key characteristics in reflow soldering are:
" Lead-free versus SnPb soldering; note that a lead-free reflow process usually leads to 
higher minimum peak temperatures (see Figure 24
) than a SnPb process, thus
reducing the process window
"  Solder paste printing issues including smearing, release, and adjusting the process 
window for a mix of large and small components on one board
"  Reflow temperature profile; this profile includes preheat, reflow (in which the board is 
heated to the peak temperature) and cooling down. It is imperative that the peak
temperature is high enough for the solder to make reliable solder joints (a solder paste
characteristic). In addition, the peak temperature must be low enough that the
packages and/or boards are not damaged. The peak temperature of the package
depends on package thickness and volume and is classified in accordance with
Table 22
 and 23
 
 
Moisture sensitivity precautions, as indicated on the packing, must be respected at all
times.
Studies have shown that small packages reach higher temperatures during reflow
soldering, see Figure 24
.
