摘要:
The invention relates to a method for forming an electrically conductive structure on a plastic substrate, wherein an ink, which contains electrically conductive solid particles, is printed on the plastic substrate, wherein copper particles are used as electrically conductive solid particles and, after the printing of the ink, only the surface regions of the plastic substrate on which the electrically conductive structure is to be formed are swept over by means of an electron beam having a first energy per unit length within a vacuum chamber, which first energy per unit length causes sintering of the copper particles.

The invention relates to an apparatus for generating accelerated electrons, comprising: a housing (101) which delimits an evacuable space (102a; 102b) and has an electron exit window (104); an inlet for supplying a working gas into the evacuable space (102); at least one first cathode (105a; 105b) and at least one first anode (101), between which a corona discharge plasma (106) can be generated in the evacuable space (102a) by means of a first applied electric voltage, wherein ions from the corona discharge plasma (106) can be accelerated onto the surface (110) of a second cathode (107) and electrons emitted by the second cathode (107) can be accelerated in the direction of the electron exit window (104) by means of a second electric voltage applied between the second cathode (107) and a second anode (108), wherein the housing (101), the second cathode (107) and the electron exit window (104) are ring-shaped, and wherein the surface perpendiculars of the electron exit window (104) and the surface region (110) of the second cathode (107) from which the electrons are emitted are oriented towards the ring interior of the ring-shaped housing (101).
