Abstract

The invention relates to a low-temperature co-fired ceramic tape casting material and a preparing method and application of the low-temperature co-fired ceramic tape casting material. The low-temperature co-fired ceramic tape casting material comprises, by weight, 35-50% of inorganic-phase components and 50-65% of organic-phase components. The inorganic-phase components include borosilicate glass powder and aluminum oxide ceramic powder, wherein the weight ratio of the borosilicate glass powder to the aluminum oxide ceramic powder is 2:3-3:2, and the borosilicate glass powder includes CuO which accounts for less than 3% of the power in weight. The organic-phase components include a solvent, an adhesion agent, a plasticizing agent and a dispersing agent, wherein the solvent is an alcohol-ester mixed solvent, and alcohol accounts for 20-70% in the mixed solvent in weight.

Description

technical field

[0001] The invention relates to a low-temperature co-fired ceramic raw belt material, a preparation method and application thereof, and belongs to the field of electronic ceramic substrate materials and the manufacture thereof. Background technique

[0002] Low temperature co-fired ceramics (Low temperature co-fired ceramics, LTCC) as a ceramic packaging substrate material, has low dielectric constant and loss, low thermal expansion coefficient (matched with silicon), high chemical stability, good mechanical performance, and can be integrated with high-conductivity metals (such as gold, silver, copper, etc.) at 900 ° C to achieve many advantages such as multi-layer wiring of ceramic substrates. packaging and device manufacturing. LTCC substrate materials are mainly composed of glass / ceramic composites. In the LTCC substrate materials that have been applied in the market, the base material generally uses borosilicate glass with low softening point, and the c...
