Dual 1-of-4 FET multiplexer/demultiplexer
13.4 Reow soldering
Key characteristics in reow soldering are:
Lead-free versus SnPb soldering; note that a lead-free reow process usually leads to
higher minimum peak temperatures (see Figure 13) than a PbSn 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
Reow temperature prole; this prole includes preheat, reow (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 classied in accordance with
Table 9 and 10
Moisture sensitivity precautions, as indicated on the packing, must be respected at all
times.
Studies have shown that small packages reach higher temperatures during reow
soldering, see Figure 13.
