Hi Technetters, I am encountering the issue that having solder balls that stucked inside the via-holes, as this was caused by the cleaning the 'misprint' boards, that the solder paste was somehow got into the via-holes by trying to scoop the solder off the board. Now, the problem is that the solder beads (from the paste) that stucked inside the via-hole so stubbornly that I am not able to get them out. We try to water-jet clean off the solder beads, it only manages to get rid 50% of them, and still there is 50% of ball/beads in the via-holes. Any good advise that enable me to get the solder balls/beads out of the via-holes completely.
