Abstract
A method of connecting a fine wire to an ultrafine wire, the fine wire exhibiting a first cross-section and the ultrafine wire exhibiting a second cross-section, the second cross-section smaller than the first cross-section, the method constituted of: providing an uninsulated portion of the fine wire exhibiting a flat surface; depositing a conductive material on the flat surface of the provided uninsulated portion of the fine wire; providing an uninsulated portion of the ultrafine wire; and bonding the provided uninsulated portion of the ultrafine wire to the deposited conductive material on the flat surface of the provided uninsulated portion of the fine wire by thermocompression.

A method of connecting an ultrafine wire to a fine wire, the fine wire exhibiting a maximal cross-section of 25-100 microns and the ultrafine wire exhibiting a maximal cross-section of less than 25 microns, the method comprising:
- providing an uninsulated portion of the fine wire exhibiting a flat surface;
- depositing gold on the flat surface of said provided uninsulated portion of the fine wire;
- providing an uninsulated portion of the ultrafine wire;
- and
- bonding said provided uninsulated portion of the ultrafine wire to said deposited gold on the flat surface of said provided uninsulated portion of the fine wire, said bonding accomplished by thermocompression utilizing a predetermined temperature and pressure profile over a predetermined time.
A method of connecting a first wire to a second wire, the first wire exhibiting a maximal cross-section of less than 25 microns and the second wire exhibiting a maximal cross-section of 25-100 microns, the method comprising bonding a predetermined portion of the first wire to gold deposited on a predetermined portion of the second wire,
- wherein said bonding is accomplished by thermocompression utilizing a predetermined temperature and pressure profile over a predetermined time.
