In no particular order: Hole diameter inadequate size for component lead... component leads are contaminated... wave solder is contaminated... also check wave solder temp; angle; dwell... hole wall plating is thin; rough and/or contaminated (micro-section and evaluate a poorly filled PTH). Surface finish of hole wall is compromised (e.g., immSN w/thick intermetalic; insufficient OSP coverage; oxidized immAG; porous ENIG). Recommendation: Perform an IPC J-003B solderability test on a BARE board. Failing that you then go to the Board House. Passing that you look to your storage; handling; soldering processes. NOTE: Some SnPb designs that later converted to Pb-Free see improved PTH fill when the PTH diameters are slightly increased.
