Abstract
A system for in-process orientation of particles used in direct-write inks for fabricating a component may include a device for polarizing direct-write particles in an aerosol. An outlet may direct the aerosol including the polarized direct-write particles on a substrate to form a component. An apparatus may cause the polarized direct-write particles to be aligned in a selected orientation to form the component with predetermined characteristics when deposited on the substrate.
Claims15
A system for in-process orientation of particles used in direct-write inks for fabricating a component, the system comprising:
- a device for polarizing direct-write particles in an aerosol, the device comprising:
- a holding chamber for retaining the aerosol including the direct-write particles;
- a positive electrically chargeable element;
- and
- a negative electrically chargeable element, wherein the direct-write particles are polarized in the holding chamber by a first electric field generated by the positive electrically chargeable element and the negative electrically chargeable element, one of the holding chamber being moved relative to the electrically chargeable elements or the electrically chargeable elements being moved relative to the holding chamber;
- an outlet to direct the aerosol including the polarized direct-write particles on a substrate to form a component;
- and
- an apparatus to cause the polarized direct-write particles to be aligned in a selected orientation to form the component with predetermined characteristics when deposited on the substrate.
A system for in-process orientation of particles used in direct-write inks for fabricating an electrical component, the system comprising:
- a holding chamber for retaining an aerosol, wherein the aerosol includes direct-write particles;
- a first structure to generate a first electric field in the holding chamber to polarize the direct-write particles in the aerosol, wherein either the holding chamber is moved relative to the first electric field or the first electric field is moved relative to the holding chamber to polarize the direct-write particles, and wherein the first structure to generate the first electric field in the holding chamber comprises:
- a positive electrically chargeable element and a negative electrically chargeable element;
- a device to move either the holding chamber relative to the positive electrically chargeable element and the negative electrically chargeable element, or to move the electrically chargeable elements relative to the holding chamber, to polarize the direct-write particles in the aerosol within the holding chamber;
- an exit nozzle to direct the aerosol including the polarized direct-write particles on a substrate to form an electrical component;
- and
- a second structure to generate a second electric field, wherein the aerosol including the polarized direct-write particles is directed through the second electric field toward the substrate and wherein the second electric field causes the polarized direct-write particles to be aligned in a selected orientation to form the electrical component with predetermined electrical characteristics when deposited on the substrate.
