Abstract

The invention relates to a chip type multilayer ceramic connector and a preparation method thereof. The chip-type multilayer ceramic connector includes a chip-type ceramic dielectric body and a plurality of terminal electrodes arranged on the chip-type ceramic dielectric body and separated from each other. A conductive pattern is formed inside the chip-type ceramic dielectric body. The conductive pattern conducts at least two of the terminal electrodes. The conductive pattern inside the chip-type ceramic dielectric body of the chip-type multilayer ceramic connector can realize the conduction of at least two terminal electrodes, so that when the chip-type multilayer ceramic connector is applied to a circuit board, the electronic components can be realized. Conduction, and because the chip ceramic dielectric body is used as the dielectric structure, the volume is small, which can meet the miniaturization requirements of electronic products.

Description

technical field [0001] The invention relates to the technical field of electronic product accessories, in particular to a chip-type multilayer ceramic connector and a preparation method thereof. Background technique [0002] With the intelligent development of society, people have higher and higher requirements for the appearance and performance of electronic products, especially for the miniaturization of electronic products. [0003] Circuit connectors are generally used to connect components on circuit boards and act as a bridge connection. There are many circuit connectors required for each electronic product, and the structures of the circuit connectors are diverse. The circuit connection and the physical connection on the circuit board should be guaranteed, and the current circuit connector has a large volume. [0004] Circuit connectors should tend to be miniaturized in order to meet the miniaturization requirements of electronic products. Contents of the inventio...
