Abstract
Electrostatic printing methods are used to allow the precise placement of small, discrete components on a substrate. The components are configured as liquid toners by coating one or more surfaces with a charge control agent which reacts with a charge director in a diluent to create a charge on the coated components allowing them to be manipulated and placed using electrical fields.
Claims12
A method for the precise placement of one or more discrete components on a substrate comprising:
- A. coating said one or more components with a charge control agent;
- B. dispersing said coated components in an aliphatic hydrocarbon diluent containing charge director material;
- wherein said charge control agent and said charge director material interact to impart an ionic charge on the coated components and an oppositely charged micelles in said diluent;
- C. applying a first electrical voltage opposite that of the charge on said components to an image plate having one or more cavities corresponding to the desired placement of said one or more components;
- thereby pulling said components into said cavities;
- D. placing said substrate proximate to said image plate;
- E. reducing said first electrical voltage and applying a second electrical voltage opposite that of the charge on said components to said substrate;
- thereby pulling and affixing said components to said substrate.
