Abstract
A method for placing material onto a target board by means of a transfer board comprising a plurality of blind holes, the method comprising the steps of immersing the transfer board in a material bath, wherein a first pressure acts on the material bath and a second pressure acts in the blind holes, and wherein the first pressure and the second pressure are substantially equal; generating a pressure difference between the first pressure and the second pressure, so that the blind holes of the transfer board are filled at least partially with the liquid material; extracting the transfer board from the material bath; and positioning the transfer board opposite to the target board, the material being expelled from the blind holes, such that the material touches the target board.
