• 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 14 and Table 15

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 19.
