Abstract
A laser-assisted deposition apparatus 20 for depositing deposition medium 3 (e.g. solder paste) from a tape 2 onto a workpiece W, comprises a coating section with a deposition material source 15, first and second regulating members 13’,14’ arranged downstream of the deposition material source 15 in spaced relation on either side of the tape 2 such that the distance between the first and second regulating members 13’,14’ regulates the thickness of deposition material 3 coated onto the tape 2 in use, a vibration unit 21,22 which is operative to agitate the deposition material 3 at the coating section, and a laser source 7 which illuminates the tape 2 to expel deposition medium 3 onto the workpiece W. The first regulating member 14’ may be a roller or a doctor blade and the second regulating member 13’ may be a roller or a flat tape support surface.
