Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of cleaning of a plate type multilayer ceramic capacitor electroplating device, in particular to a centrifugal cylinder plating layer regeneration treatment device. BACKGROUND

[0002] MLCC (Multi-layers Ceramic Capacitor), i.e. a plate type multilayer ceramic capacitor, also known as a plate capacitor, a laminated capacitor, a stacked capacitor, etc., is the most widely used capacitor. The MLCC is formed by stacking ceramic dielectric films with surface printed electrodes (internal electrodes) in an interleaved manner, sintering at high temperature to form a ceramic block, and then sealing a metal layer (external electrode) at both ends of the ceramic block. When preparing the MLCC, the following processes are generally performed: batching, casting, printing, layering, laminating, cutting, degassing, sintering, chamfering, end sealing, and electroplating.

[0003] The electroplating process generally uses vibration plating, barrel plating, etc. As the circuit integration of the chip and the substrate is getting higher and higher, the MLCC product is also developing towards miniaturization. The existing barrel plating and vibration plating process is no longer suitable for use in micro MLCC products, and a new electroplating process, i.e. centrifugal plating, needs to be developed. In centrifugal plating, the product is subjected to centrifugal motion in a centrifugal cylinder (also called a centrifugal cup in some scenarios). The MLCC product is uniformly distributed on the surface of the centrifugal cylinder under the action of centrifugal force. The centrifugal cylinder is in contact with the cathode, and the MLCC product is electrified on the surface of the centrifugal cylinder to be electroplated. Centrifugal plating improves the plating defects caused by the inability of the product to fully disperse during the electroplating process due to its small size. Miniature MLCCs such as 0201 (0.6mm / 0.3mm / 0.3mm), 01005 (0.4mm / 0.2mm / 0.2mm), etc. have widely used centrifugal cylinder electroplating process.

[0004] The centrifugal cylinder is in contact with the circuit cathode. In the electroplating process, in addition to the product that needs to be electroplated, the surface of the centrifugal cylinder will also be electroplated. If the plating layer on the surface of the centrifugal cylinder is not treated for a long time, it will cause material sticking, cylinder explosion (the plating layer on the centrifugal cylinder automatically falls off during the electroplating process), and other defects. The traditional method is to manually strip the plating layer on the centrifugal cylinder after 5-15 times of electroplating. Manual stripping of the plating layer on the centrifugal cylinder has the following problems:

[0005] The plating layer is tight, and it takes a long time to strip. Manual stripping of one centrifugal cylinder takes 0.5-1.0 hours.

[0006] Manual stripping is not easy to strip cleanly, and the remaining impurity plating layer can easily cause cylinder explosion defects.

[0007] The centrifugal cylinder coating must have a certain thickness to be manually stripped off, and generally can be stripped off after being used for more than 5 times, and individual specifications can be stripped off due to cylinder explosion caused by multiple uses of the centrifugal cylinder. Content of the utility model

[0008] Therefore, the centrifugal cylinder coating regeneration treatment equipment is provided to solve the above technical problems and improve the centrifugal cylinder coating treatment efficiency.
