  • Method of manufacturing and transferring metallic droplets
    Patent number: 5935294
    Abstract: A method of manufacturing metallic droplets (9), comprising the following steps:(a) providing a substrate (1) which is substantially transparent to radiation of wavelength .lambda., one face (1a) of the substrate (1) being provided with a metallic layer (3) which is partitioned into an array of lands (5);(b) directing a laser beam (7) of wavelength .lambda. through the substrate (1) onto a land (5), thereby causing rapid melting of the land (5) and its detachment from the substrate (1) in the form of a molten droplet (9). In a preferential embodiment of the method, the molten droplet (9) is "shot" onto a target substrate (21) before solidifying.
