Apparatus and method for mounting particles on a carrier

摘要

Method and apparatus for individually positioning and mounting particles on a target carrier according to a predefined pattern. In particular the particles are spheres of an electrically chargeable material with a diameter in the range of 10 micrometer up to one millimeter and are electrically conductive.

主权项

1. A mounting tool for individual positioning and mounting particles on a target carrier, the mounting tool comprising:
a conductive storage bin for containing the particles, the particles having a particle diameter; an intermediate carrier provided with a first pattern of conductive capture areas provided with an insulating layer, the areas having an area diameter, where the area diameter is less than or substantially equal to the particle diameter in order for each capture area to capture substantially one particle; a first transfer device configured to transfer the particles from the storage bin to the intermediate carrier according to the first pattern, the first transfer device comprising an electrical charging device configured to electrically charge the capture areas; a device configured to bring the intermediate carrier into the direct vicinity of the particles in such a way that particles are attracted to the charged capture areas; and a second transfer device configured to transfer the particles from the intermediate carrier to the target carrier according to the first pattern, the second transfer device comprising a device configured to position the intermediate carrier in the direct vicinity of the target carrier and a device configured to position and fix the particles on the target carrier.
