For further information on temperature profiles, refer to Application Note AN10365
“Surface mount reflow soldering description” .
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 reflow soldering description” .
Wave soldering is not suitable for this package.
All NXP WLCSP packages are lead-free.
Board mounting of a WLCSP requires several steps:
Key characteristics in reflow soldering are:
1. Solder paste printing on the PCB
2. Component placement with a pick and place machine
3. The reflow soldering itself
