Printing screen plate for rapid detection of electrode dislocation, MLCC and detection method therefor

Abstract

The invention discloses a printing screen plate for rapid detection of electrode dislocation, an MLCC and a detection method therefor. The printing screen plate for rapid detection of electrode dislocation comprises a screen plate body, and a plurality of parallel and staggered inner electrode graphs are arranged on the screen plate body; an identification graph is arranged in a screen plate body minor axis direction between two neighboring inner electrode graphs, and the identification graph is used for detecting electrode dislocation; the identification graph is arranged at a blank margin part of the printing screen plate, the identification graph along with the inner electrodes is printed on a ceramic membrane sheet during printing processes, and therefore an identification part is formed; after subsequent laminating and cutting processes, the identification part can be displayed on a side face of a chip, alignment condition of the inner electrodes can be directly determined via detection of graph arrangement of the identification part, cutting bias or displacement of the minor axis and a major axis can be rapidly detected, detection efficiency can be greatly improved, and product quality can be ensured.

Description

technical field [0001] The invention relates to the field of ceramic element silk screen design, in particular to a printing screen plate, MLCC and a detection method thereof for machine rapid detection of electrode displacement. Background technique [0002] In the printing process of ceramic components such as MLCC (Multi-layer Ceramic Chip Capacitors, chip multilayer ceramic capacitors), the traditional printing pattern consists of MLCC inner electrodes (001) and short-axis blanks (002) and long-axis blanks. (003) composition (as figure 1 shown), the printed membranes are laminated and cut to form chips. The internal electrode arrangement in the short-axis direction can be seen on the two end faces of the dicing chip, and the short-axis shear deviation or short-axis displacement can be quickly checked, while the internal electrode arrangement in the long-axis direction is blocked by the side of the dicing chip (such as figure 2 shown), which makes it impossible to dire...

AI Technical Summary

Problems solved by technology

The internal electrode arrangement in the short axis direction can be seen on both ends of the dicing chip, and the short axis deviation or short axis displacement can be quickly checked, while the internal electrode arrangement in the long axis direction is blocked by the side edge of the dicing chip (such as figure 2 shown), which makes it impossible to directly check the internal electrode arrangement through the appearance of the side of the chip

At present, the method of inspecting the internal electrode arrangement in the long axis direction of the cut chip is to use a blade to cut the chip along the long axis direction, and then check whether the internal electrodes have long axis deviation or long axis displacement. The long axis direction inspection operation is cumbersome and inefficient. Low, the probability of detection failure is low, and there is a risk of long-axis deviation or long-axis shifting into the next process, affecting product quality
