7 results about "Conductive paste" patented technology

In a case of multilayer circuit boards where a plurality of conventional films are used as insulating layers, the films are connected with each other using an adhesive, and therefore, the adhesive sometimes negatively affects reduction in thickness. Therefore, a plurality of two-sided boards with films used therein are pasted together with a paste connection layer interposed therebetween, the paste connection layer being configured such that through holes formed in a prepreg are filled in with a conductive paste which is then cured, and second wires are electrically connected with each other through the conductive paste with which the through holes formed in the paste connection layer in advance are filled in, and thus, a multilayer board can be provided without using an adhesive, and the entirety of the multilayer circuit board can be reduced in thickness.

The invention relates to the technical field of conductive paste smearing, in particular to an automatic conductive paste smearing device for a power control cabinet. The automatic conductive paste smearing device comprises a drawer body, a connecting mechanism is mounted on the drawer body, a storage mechanism is mounted on the drawer body, a closing mechanism is mounted on the storage mechanism, and a smearing mechanism is arranged in the connecting mechanism. A protection mechanism is arranged in the connecting mechanism, and a gas injection mechanism is installed in the drawer. Through insertion of the drawer body and the control cabinet, protection of a plug-in unit is facilitated through the connecting mechanism, conductive paste is smeared into the connecting mechanism through the smearing mechanism, the conductive paste is conveniently stored under the action of the storage mechanism, the conductive paste is conveniently injected into the storage mechanism through the closing mechanism, the smearing work of the smearing mechanism is facilitated, under the action of the gas injection mechanism, the interior of the storage mechanism is pressurized, and the conductive paste in the storage mechanism can be smoothly guided into the interior of the smearing mechanism for smearing work.
