Problems solved by technology

The sintering shrinkage behavior of the above-mentioned ceramics is exactly the same as that of the internal electrodes, which may also cause internal cracking defects, which will affect the reliability and yield of components, and promote defects such as discontinuous contact, resistance value change, capacitance decay, and excessive leakage.
When the storage temperature and humidity change, this kind of MLCC with internal cracks and poor electrical quality will show short circuit, uncontrolled current flow, and disorder due to functional damage. As a result, the product will heat up, which may cause the Sony lithium battery to explode. class event

Embodiment Construction

[0070] See figure 1 a, the present invention provides a sintering method, which includes the steps of: providing a first green body 1, forming a second green body 2 on the first green body, and simultaneously heating the first green body and the second green body to a specific temperature 3 , wherein the specific temperature enables complete sintering 4 of the first green body. In a preferred embodiment of the present invention, the specific temperature may be above 600-2000° C., and the sintering temperature of the second green body needs to be higher than the specific temperature. In addition, the first green body has a shrinkage amount, and shrinkage of the shrinkage amount is suppressed by the second green body. The first green body can be formed by alternately stacking multiple ceramic green bodies and multiple electrode green bodies.

[0071] See figure 1 b. According to the inventive spirit of the present invention, it can also be used to provide another sintering me...

Abstract

The invention solves the problem of incapability of achieving better electrode continuity after sintering due to mismatching of internal electrode shrinkage rate and ceramic material shrinkage rate of a multilayer ceramic assembly in a sintering process. A former document indicates that the problem of electrode discontinuity of the multilayer ceramic assembly can be improved by using rapid sintering. According to the method provided by the invention, the better electrode continuity can be achieved by the multilayer ceramic assembly without using the rapid sintering.

Description

technical field [0001] The invention is a sintering method, in particular, the invention relates to a shrinkage-inhibiting sintering method for improving electrode continuity of laminated ceramic components. Background technique [0002] Passive Components are indispensable components in the circuit design of electronic products. Compared with microcontrollers, memory, etc., although capacitors are not key components, their quality is related to the performance of electronic products. Traditional mica capacitors, paper capacitors, ceramic capacitors, plastic film capacitors, electrolytic capacitors, and the current advanced multilayer ceramic capacitors (Multilayer Ceramic Capacitors, MLCC) are all capacitors, which are used for energy storage, filtering, bypassing, Coupling, anti-coupling and tuning oscillation, etc. At present, capacitors are components of PCs, mobile phones, and automotive electronics. Multilayer ceramic capacitors with small size, large capacitance, an...
