Abstract

The invention discloses a low-temperature co-fired ceramic colloid and a preparation method and application thereof. The low-temperature co-fired ceramic colloid is prepared from the following raw materials in parts by mass: 60-90 parts of metal powder, 0.5-20 parts of glass powder, 3-30 parts of an organic adhesive and 1-28 parts of a solvent. The glass powder is added to a noble metal such as silver metal powder, gold metal powder, palladium metal powder, copper metal powder or nickel metal powder. If the glass powder is added into the silver metal powder and sintering in the atmosphere is conducted, a high adhesion force of 30-50 N<2> (wherein 1 kgf / cm<2> is equal to 9.8 N / cm<2>) can be produced; and if the glass powder is added into the copper powder and sintering in the inert atmosphere is conducted, a high adhesion force of 30-50 N<2> (wherein 1 kgf / cm<2> is equal to 9.8 N / cm<2>) can be produced.

Description

technical field [0001] The invention belongs to the field of electrode paste of low-temperature co-fired ceramics and high-frequency microwave dielectric ceramics, and in particular relates to low-temperature co-fired ceramic colloids and a preparation method and application thereof. Background technique [0002] With the development of electronic products, the requirements of the market are gradually moving towards the direction of miniaturization, high capacity, thin film and low energy consumption, which makes the circuit components face the problem of reducing the volume, so the laminated ceramic passive components that meet the market requirements The low-temperature process and high-frequency technology that came into being and can effectively reduce costs at the same time are the development trends of digital 3C products. [0003] Since the available frequencies for 5G communication transmission are expected to be 24.25-27.5GHz, 31.8-33.4GHz or 37-40.5GHz, the industr...
