Problems solved by technology

However, when the organic gold conductor paste is sintered, the gold compound gradually decomposes into simple gold and forms tiny grains, and the grains grow gradually during further sintering. When the grain boundaries of the two grains contact, they will reunite and fuse to form Large particles make the appearance of the gold film rough after sintering, and the smoothness is poor

Abstract

The invention discloses an organic gold conductor paste. The organic gold conductor paste includes gold compounds, other metal compounds and organic carriers, and the other metal compounds include lead compounds, bismuth compounds, rhodium compounds, silicon compounds, and boron compounds. and vanadium compound, in terms of element weight, Rh / Au=0.0010-0.0050 in the organic metal conductive paste. By optimizing the ratio of Rh / Au in the composition of the organic gold conductor paste, the present invention can effectively improve the appearance of the gold film after sintering, make the gold film smooth, and avoid the obvious increase of the square resistance of the gold film.

Description

technical field [0001] The invention relates to the technical field of electronic paste, in particular to an organic gold conductor paste. Background technique [0002] Gold-based conductor paste has the characteristics of high electrical conductivity, stable performance, easy thermocompression welding, and high bonding strength with the substrate. It is widely used in the electronic components such as hybrid integrated circuits, microwave hybrid integrated circuits, multi-chip components, and thermal print heads. Production. Among them, organic gold conductive paste has the characteristics of low cost and low sintering temperature, and is often used as a conductive electrode in thermal printing modules. The composition of the existing organic gold conductor paste includes gold compound, other metal compounds and organic carrier. However, when the organic gold conductor paste is sintered, the gold compound gradually decomposes into simple gold and forms tiny grains, and th...
