QFP Soldering
1. Apply the solder paste.
Apply the proper quantity of solder paste
and install the SMD on the PWB.
2. Preheat the SMD.
Preheat the SMD as shown in the photo.
3. Soldering
Heat the lead frame evenly.
4. Cleaning
When soldering is completed, clean the
residual flux from the board with an
appropriate cleaner.
NOTE:
Soldering with hot air has many advantages, such
as the inherent ability to pre-heat the component
being replaced. As with any soldering process,
however, there is always the possibility of forming
solder balls, bridges between leads, and inadequate
solder joints. Always inspect the finished solder
joints for structural and electrical integrity.
