        Hi Carmen:
        Solder ball is an indication that the process needs to be refined. Moisture in the barrels, or any cavity can cause the sudden explosion of vapor which brings the solder up and causes the solder balls. I would make sure that boards are dried. Perhaps as you say it may be the solder, try other type of solder.
        Good luck,
        Ramon

we use a no clean solder and flux, which i believe is what is causing the
solder balls, any suggestions on what to do to cut down the solder balls.
