Abstract
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.
Claims2
A method for individually positioning and mounting particles on a target carrier, the method comprising:
- a first transferring step of transferring the particles from a storage bin to an intermediate carrier and a second transferring step of transferring the particles from the intermediate carrier to the target carrier,
- the first transferring step further comprising the steps of:
- applying a voltage to a pattern of interconnected conductive capture areas on a first side of the intermediate carrier, the pattern being covered with an insulating layer;
- bringing the first side of the intermediate carrier in the direct vicinity of particles stored in the conductive storage bin;
- turning the bin and the intermediate carrier together around an axis parallel to the intermediate carrier;
- disconnecting the voltage from the interconnected conductive capture areas;
- and
- moving the intermediate carrier with a monolayer of particles according to the pattern from the bin;
- and
- the second transferring step further comprising the steps of:
- positioning the intermediate carrier with the monolayer of particles according to the pattern in front of the target carrier, the target carrier being provided with an adhesive layer;
- pushing the monolayer of particles against the adhesive layer of the target carrier;
- and
- curing the adhesive layer for fixing the monolayer of particles onto the target carrier.
