Product data sheet
9.1 Introduction to soldering WLCSP packages
9.2 Board mounting
9.3 Reflow soldering
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:

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

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) 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 classified in accordance with
Lead-free process (from J-STD-020C)
