Defect : Excessive solder Process/machine infomation :  Board type - Double sided  Solderability protection - OSP  Flux carrier - Water  Preheat type - Forced Convection  Process solutions Conveyor speed too fast. a. Dwell time too short. Flux not active enough or solids percentage too low. Solder temperature too low. Not enough flux.   Board and design solutions Board/component solderability. Lead length to pad size ratio incorrect. Component layout, orientation.
