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 SMT Net Team Member,
I always have problem at MY SMT process and production side, Every time product running at my production side always found a lot solder Ball issue near the pad of SMT chip component. We had quite hard to do the trouble shoot to get the actual root cause of that But seems like my work hard is no result. Currently my process is on top side used solder paste and at Bottom side used epoxy process. My solder paste is Kester R811. my reflow setting is 130, 170, 185, 180, 190, 250.
Any one of you face the similar problem as mine ?, any one of you can solved my problem ? Is all the water soluble solder paste must have the solder ball after reflow ?
