An apparatus for cleaning electronic packages comprises a tank containing cleaning fluid and a holder above the tank that supports the electronic packages above a top surface of the cleaning fluid with the electronic packages facing the cleaning fluid. Acoustic energy generators are immersed in the cleaning fluid for generating and propagating acoustic energy towards the top surface of the cleaning fluid to create streaming fluid jets projecting upwardly at the top surface to contact and clean the electronic packages supported on the holder.
