16. Soldering
16.1 Introduction to soldering WLCSP packages
This text provides a very brief insight into a complex technology. A more in-depth account
of soldering WLCSP (Wafer Level Chip-Size Packages) can be found in Application Note
AN10439 “Wafer Level Chip Scale Package” and in Application Note AN10365 “Surface
mount reow soldering description”.
Wave soldering is not suitable for this package.
16.2 Board mounting
Board mounting of a WLCSP requires several steps:
1. Solder paste printing on the PCB
2. Component placement with a pick and place machine
3. The reow soldering itself
16.3 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 23) than a PbSn process, thus
reducing the process window
Solder paste printing issues, such as 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) while being 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 35 and 36
Table 35.
