Solder paste is a material used in the manufacture of printed circuit boards to connect surface mount components to pads on the board. It is also possible to solder through hole pin in paste components by print solder paste in/over the holes.

Hi, all. There is one 0.8mmX0.8mm QFN on almost of our PWBAs. But the quality report showed that we got bad solder quality for this component. My question is which elements are the root cause for this situation frequently? Thanks.
