Abstract

The invention discloses an electronic electrode paste with high oxidation resistance, and a preparation method thereof. The electronic electrode paste comprises, by weight, 54-60% of molybdenum powder, 30-66% of a solvent and 7-13% of white glue. The electronic electrode paste is obtained through solvent preparation, white glue preparation, batching, ball milling, rolling and defoaming. The prepared electronic electrode paste has good oxidation resistance, and sintered molybdenum crystals have good metallization performance, so that electrode lead connection is extremely firm.

Description

technical field [0001] The invention belongs to the technical field of electronic electrode slurry production, and relates to an electronic electrode slurry with strong oxidation resistance and a preparation method thereof. Background technique [0002] Conductive paste, also known as conductive adhesive, is a mixture of precious metal powder and base metal powder, glass powder and synthetic resin. The conductive paste is applied to the required part of the substrate by screen printing or other methods, and then heated at a temperature of Conductors are fired at 400-1000°C, and are mainly used for wiring of thick film integrated circuits, electrodes of ceramic capacitors, and leads of hybrid integrated circuits. When the conductive paste is used as the electrode of a ceramic capacitor or a thick film integrated circuit, it needs to have good conductivity with the integrated circuit, and at the same time it needs to be fixed to the connecting lead, and the electrode is genera...
