Abstract

The invention discloses a resin gold conductor paste, which is formed by fully mixing terpineol, DL-methionine, chloroauric acid, silver nitrate and an organometallic compound, and then performing vacuum distillation heat reaction, wherein the organometallic compound It is a mixture of manganese isooctate, bismuth isooctanoate, cobalt isooctanoate, copper isooctanoate, zinc isooctanoate, zirconium isooctanoate. The resin gold conductor paste prepared by vacuum distillation heat reaction in the present invention has no lead, no rhodium, no palladium, environmental protection, low cost, smooth surface after sintering, good lapping stability with silver paste, and large bonding tension, etc. Features, suitable for the use requirements of thick film printing process, and can meet the use requirements of capacitive sensors, thermal print heads and other products.

Description

technical field [0001] The invention belongs to the technical field of conductor paste, and in particular relates to a resin gold conductor paste. Background technique [0002] Gold 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 production of electronic components such as hybrid integrated circuits, microwave hybrid integrated circuits, multi-chip components, and thermal print heads. . The existing organic gold conductor paste is made of polymer gold compound, the film layer is thin and dense, and the material cost is only 10% of the inorganic gold powder paste. Combined with photolithography technology, lines with line width and spacing up to 10 μm can be produced, and the performance can reach the level of sputtering. The level of gold injection is widely used in the production of high-performance products such as thermal pri...
