Just feel relieved that we didn't go to the matt on the use of "leaching" rather than "dissolution". And you thought this was easy, eh?

Hi Pavel, what you see is most probably caused by to much solder. There�re plenty of hints to avoid this in the archives, just use the "search" function and look for "solder beads" and "solder balls". That will bring you on the right track. Good lu
