Problems solved by technology

However, the internal structure of the existing molded multi-core ceramic capacitors is a single-layer or double-layer chip-mount welding structure, which is of a single type. Due to the restriction of the design structure, the maximum number of chips carried by the product is limited, which cannot meet the increasing customer needs.

Abstract

The invention provides a double-layer-structure mould pressing multi-core-group ceramic capacitor and a production method thereof. The multi-core-group ceramic capacitor comprises a plastic package shell, a frame arranged in the plastic package shell, four capacitor chip modules and an insulating spacer, wherein the frame comprises a first leading-out end, a second leading-out end, a lower welding layer and an upper welding layer, the capacitor chip modules are welded at the upper and lower ends of the upper and lower welding layers, the insulating spacer is arranged between the two adjacent capacitor chip modules to play a role in isolation, and the first and second leading-out ends respectively extend out of the plastic package shell. The multi-core-group ceramic capacitor realizes multi-core-group capacitor lamination in space, greatly increases the capacitance, saves the welding area, and has higher electrical performance and reliability.

Description

technical field [0001] The invention relates to a double-layer structure molded multi-core group ceramic capacitor and a production method thereof. Background technique [0002] Ceramic capacitors have the characteristics of small size, large specific volume, long life, high reliability, and suitable for surface mounting, in addition to the characteristics of "blocking direct traffic" of capacitors. With the rapid development of the world's electronics industry, as the basic components of the electronics industry, ceramic capacitors are also developing at an astonishing speed, increasing at a rate of 10% to 15% every year. At present, the demand for ceramic capacitors in the world is more than 200 billion pieces, 70% of which come from Japan, followed by Europe, America and Southeast Asia (including China). With the improvement of the reliability and integration of chip products, its scope of use is wider and wider, and it is widely used in various military and civilian ele...
