4 Carrier Board Solder Paste

Depending on the final application of the customer board and assembly constraints, either a low-temperature soldering or common lead-free soldering process can be used. Two types of solder paste are available, depending on the assembly process and the reflow profile:

  • SnBi Eutectic composition for low-temperature lead-free solder reflow applications
  • SnAgCu Eutectic composition for most common lead-free solder reflow applications

For each solution, the reflow profile must be adapted according to the solder paste used during the assembly phase. Some examples are given in the next paragraph.
