Hi Charles, I once faced with the problem on such issue. I solved by using a rubber squeegee. And I was consistently getting 99.7% yield rate or even higher, without solder short and unsoldered joint. I guess many people do not use rubber squeegee nowsaday. Getting a good print definition is important and getting a good stencil is important so as to have a good paste release. And one more important area is the solderpaste. Good paste provides good print defintion as well as resolving bridging issue. Sometimes, I use manual printing process on 20 mil pitch components, and so far there is no issue on bridging and no solder or insufficient solder. Good Luck.
