Claims
- 1. A method for making a field-emitting cathode assembly, comprising:
providing a non-conductive substrate, the substrate having a first and a second surface, and a first conductive pin electrically connected to the first surface and extending from the second surface providing a field-emitting device having an emitting array and attaching the device to the first surface and electrically connecting the device to the first conductive pin; electrically connecting at least one electrode of the field-emitting device to a second conductive pin, the second conductive pin extending from the second surface; providing an alignment member having a least one aperture therein and a selected diameter; providing a spacer to place the alignment member at a selected distance from the substrate; and joining the substrate and alignment member at a selected spaced-apart distance.
- 2. The method of claim 1 wherein the method of joining is selected from the methods of welding, brazing and applying adhesive.
- 3. The method of claim 1 wherein the alignment member is a disk and the disk further comprises a cylindrical side therein.
- 4. The method of claim 1 wherein the alignment member is a can.
- 5. A method for assembling an electron gun, comprising:
providing a field-emitting cathode assembly having an alignment member, the alignment member having at least one aperture and a selected diameter; providing a lens to be a part of the electron gun, the lens having an aperture; providing an aligning tool adapted to fit in the aperture of the alignment member and the lens; and placing the aligning tool in the apertures of the alignment member and the focusing lens so as to align the apertures and placing a shim between the alignment member and the lens so as to provide a selected distance therebetween; and glass beading the field-emitting cathode assembly and the lens.
- 6. The method of claim 5 wherein the alignment member is a can, the can further comprising wings attached thereto to produce the selected diameter.
