If it's a spray, usually balls, originating from a definable point it's probably a paste problem. If your paste dries out on the surface of the deposition and forms a crust pressure will build up inside when the flux volitalizes during reflow. When it erupts you get a spray. 1. old, dry paste 2. too long between paste deposition and reflow 3. bad profile |
