Method for forming a conductor path structure on an electrode surface of an electronic component
View Patent ↗Various embodiments may relate to a method for forming a conductor path structure on an electrode surface of an electronic component. The method includes introducing electrically conductive metal particles into an insulating carrier material, producing a mixed composition by mixing the carrier material with the metal particles, applying the mixed composition to the electrode surface, separating the metal particles from the carrier material, allowing the metal particles to become attached to the electrode surface, fixing the metal particles attached to the electrode surface, and curing the carrier material.
1. A method for forming a conductor path structure on an electrode surface of an electronic component, the method comprising:
introducing electrically conductive metal particles into an insulating carrier material,
producing a mixed composition by mixing the carrier material with the metal particles,
applying the mixed composition to the electrode surface,
separating the metal particles from the carrier material within the mixed composition,
allowing the metal particles to become attached to the electrode surface by creating a magnetic field that extends through the electrode surface, so that the metal particles in the mixed composition are guided in the direction of the electrode surface by means of the magnetic field,
fixing the metal particles attached to the electrode surface, and
curing the carrier material.
2. The method as claimed in claim 1 ,
wherein the metal particles is distributed homogeneously in the carrier material during the mixing of the metal particles with the carrier material.
3. The method as claimed in claim 1 ,
wherein the mixed composition is applied to the electrode surface in multiple paths.
4. The method as claimed in claim 1 ,
wherein the mixed composition is applied to the electrode surface by a printing process.
5. The method as claimed in claim 1 ,
wherein the fixing of the metal particles on the electrode surface is performed by means of an irradiation process.
6. The method as claimed in claim 5 ,
wherein ultraviolet light is used in the irradiation process.
7. The method as claimed in claim 1 ,
wherein the curing of the carrier material is performed in such a way that in a cured state the metal particles are covered over by the carrier material.
8. The method as claimed in claim 1 ,
the curing of the carrier material is performed by supplying heat.
9. The method as claimed in claim 8 ,
wherein a flow-transformation of edges of a metal structure formed by the metal particles is by means of a reflow process.
10. The method as claimed in claim 1 ,
wherein nano metal particles are used as the metal particles.
