Problems solved by technology

This method has many disadvantages. One is that the thickness of the screen film of a certain mesh is limited, and the adjustment range of printing parameters is also limited, but it can be adjusted within a certain small range; It is 1 / 2 circle (the number of inner electrode circles) or more, and the gap between the thicker lead-out electrode and the shrinkage ratio of the ceramic body material during sintering is widened, and the product is prone to cracking and other defects and serious reliability defects

Embodiment Construction

[0034] The present invention will be further described below in conjunction with the accompanying drawings and preferred embodiments.

[0035] Hereinafter, embodiments of the laminated coil component and its manufacturing method according to the present invention will be described with reference to the drawings.

[0036] A laminated coil component such as figure 1 As shown, it is composed of a ceramic body 1 and an external electrode 15 . The ceramic body 1 is composed of laminated multi-layer ceramic body layers 10, internal electrodes 13 connected sequentially in the form of coils formed on the ceramic body layer 10, and lead-out electrodes connected to at least a part of the internal electrodes 13 and at the same time connected to the external electrodes 15. 11 composed structures. The external electrode 15 and the lead-out electrode 11 are connected to each other through the thickened electrode 14 .

[0037] Below, the specific method of producing the electronic compone...

Abstract

The invention provides a bank wound coil component and a method for manufacturing the same. The bank wound coil component is characterized by comprising a body comprising at least two layers of carrier layers arranged in turn; conductors formed on the adjacent carrier layers are electrically connected with one another through internal electrodes to form a coil conductor which is electrically connected with external electrodes through leading-out electrodes on upper and lower substrates of the carrier layers positioned at two ends respectively; and the external electrodes are connected with the leading-out electrodes through thickening electrodes.

Description

technical field [0001] The invention relates to a laminated coil component and a manufacturing method thereof. Background technique [0002] With the wide application of electronic components, while paying attention to the performance of the components, more attention is paid to the reliability of the components, especially the life reliability. Improve product reliability, mainly from two aspects. One is to improve the printing effect of the internal electrodes and the connection effect between the internal electrodes, and improve the connection reliability between the internal electrodes, and the other is to improve the connection reliability between the lead-out electrodes and the external electrodes. [0003] The traditional method to improve the reliability of the connection between the lead-out electrode and the external electrode is to increase the ink volume by increasing the thickness of the printing screen, adjusting the printing pressure, etc., thereby increasing...
