Electron Beam Curing Technology    

Apparatus and Methods for Curing Ink on a Substrate Using Scanning Electron Beam

Overview

The technology offered is ideal for curing ink/organics where thermal budget becomes an issue in conventional thermal curing systems. It is also critical when ink shelf life may be an issue. The electron beam cure technology/know-how can potentially help the buyer/licensee in reducing engineering/development costs and time to market. A movable electron beam emitter allows for curing of large substrates/areas. The electron beam emitter is provided by any reputable OEM .

Features of the system -
Houses an 80 kV, 20mA electron beam used to polymerize the wet inks on the substrate. The beam spot is confined to a 10.5" x 2" area.
X and Y-axis linear motors, controlled by the a computer, position the electron beam emitter as the substrate is held in place by a vacuum chuck.
Water cooled emitter.The curing process occurs in an aluminum and lead plate enclosure to protect the operator from the hazards of X-ray radiation.
Viewing ports are equipped with a removable X-ray shielding cover.
Nitrogen purge during curing prevents the generation of ozone from oxygen present in the ambient air. Nitrogen is exhausted from the bottom of the module to general facilities exhaust. A narrow slit I/O door allows the robot end-effector to load the substrate onto the stage. The I/O door is safety interlocked to the operation of the emitter for manual loading and unloading.
The module frame supports the weight of the emitter and enclosure.An oxygen analyzer and the emitter high voltage power supply are mounted in the frame.

Primary Application of the Technology

Curing of ink and organic materials on substrates that can stand low thermal budget

The seller would like to be granted a license back.

Patent Summary

U.S. Patent Classes & Classifications Covered in this listing:

Class 427: Coating Processes

This is the generic class for: A. applying or obtaining a coating on a surface. The coating may be hard or soft, permanent or transitory, supplied solely by extraneous materials or supplied wholly or in part by the base material. B. impregnating a base by causing a coating material to extend or penetrate into the base material, or into the interstices of a porous, cellular or foraminous material. C. taking preparatory treatments of the base material, subsequent treatments of the coated base material and other ancillary noncoating operations claimed, per se, processes limited to etching for making a base more compatible with, or adherent to, the coating wherein the base is the substrate (work) onto which a coating is applied are included.

Subclass 496: High energy electromagnetic radiation or high energy particles utilized (e.g., gamma rays, X-rays, atomic particles, i.e., alpha rays, beta rays, electrons, etc.)
Subclass 8: MEASURING, TESTING, OR INDICATING

Class 347: Incremental Printing Of Symbolic Information

Processes and apparatus for conveying information by selectively creating on a medium a visibly distinguishable symbol or mark composed of a plurality of portions; created portion by portion as, for example, by pixels or dots. The symbol or mark may be an alphanumeric character or an image.

Subclass 102: Drying or curing
