Description

MLCC chip separation device and MLCC chip separation method {Separation Apparatus of multilayer ceramic capacitor and Separation Method thereof}

The present invention relates to an apparatus and method for separating a chip from a release tape to which a plurality of chips are attached, and more particularly, to a plurality of chips having a small size such as a multi-layer ceramic capacitor (MLCC) attached thereto. The present invention relates to a chip separation device capable of improving productivity by easily separating chips from a release tape, and a chip separation method using the device.

MLCC (Multi-Layer Ceramic Capacitor) is one of the capacitors with the function of accumulating electricity. It is manufactured by alternately stacking non-conductive ceramic layers and conducting internal electrode layers. It stably regulates the flow of electricity in electronic products and acts like a dam that controls the supply and demand of current, which prevents electromagnetic interference between parts. Demand for MLCC is explosively increasing as new markets such as autonomous vehicles, Internet of Things (IoT), and 5G (5G) communication are opened on the flow of the 4th industrial revolution.

As shown in FIG. 1, the MLCC process includes foil casting, inner electrode printing, stacking, and lamination including powder fabrication, slurry fabrication, and casting. , cutting, binder burn out/sintering, tumbling, termination dipping, termination firing, plating, sorting/inspection ) and taping process. A more detailed look at each process is as follows.

The powder manufacturing process is a process of reducing the powder particle size through a mixing process to secure the physical/chemical uniformity of the mixed powder, a calcination process that changes the physical/chemical properties of the mixed powder through heat treatment, and a grinding process.

In the foil casting process, ceramic powder, polymer binder, dispersant, and solvent are evenly mixed, and a repulsive force is applied to the particles inside the slurry through a dispersing facility to produce a well-dispersed slurry to secure formability, and to evenly spread the slurry on the PET film. As a process of coating and molding, it is a process that determines the characteristics of a ceramic sheet and can be said to be the first process in the actual product process.

The printing process is a process of printing internal electrodes using screen mesh or GRVURE copper plate on a ceramic sheet, and the capacitance value of MLCC is determined.

The lamination process is a process in which the printed sheets are peeled off and stacked repeatedly at a predetermined location as many times as desired, and the overall property value of the MLCC is determined.

The compression process applies pressure to the stacked sheets to make the multi-layer green ceramic sheet into a single-layer ceramic capacitor. During compression, high packing density is formed by rearranging the particles.

The cutting process is a process of cutting a laminated sheet composed of powder and polymer to a predetermined size using a blade or a dicing saw.

The calcination/firing process is a process to increase the insulation of resistance and improve reliability by removing binder through heat treatment and bonding powder to make green chips (cut chips) into chips with desired microstructure and electrical characteristics.

The polishing process is a process to improve the bondability with the external electrode by exposing the shrunken inner electrode by grinding and rounding the fragile edges after firing so that they do not collide with each other and break.

The external electrode application process is a process of forming terminals on both ends of the polished chip. In order to realize good electrical characteristics, the shape of the formed terminals must be uniform and uniform.

In the external electrode firing process, the mechanical strength of the external electrode is increased through heat treatment and adhesion to the ceramic is increased.

The plating process improves solderability in the SMT process through Ni and Sn plating and prevents corrosion of the electrode.

The selection/measurement process is a process for measuring the electrical characteristics of commercialized MLCCs, measuring capacity/dielectric loss/insulation resistance, etc. to separate defective products from mass-produced products, and is the last step in the manufacturing process.

The taping process is a process in which mass-produced products are packaged and shipped for delivery to customers.

The MLCC is manufactured as shown in FIG. 1 through the above-described process. In particular, in the conventionally known manufacturing method after performing the cutting process and before performing the plasticizing/firing process, the operator must remove the green chip from the cut release tape of the MLCC laminated sheet. There was a problem in that productivity was lowered because it was necessary to perform the work of separating one by one.

Therefore, there is a need to develop a chip separation technology capable of solving these problems.

The adhesive tape 170 to which the MLCC laminated sheet is attached can be moved to the secondary roller unit 140 .

When the pressing unit 180 is formed in this way, the MLCC laminated sheet supply unit 160 moves downward from the region where the conveyor belt member 161 comes into contact with the rotation center of the pressing unit 180, not the primary roller unit 130 . It has the same structure as the chip separation device according to an embodiment of the present invention, except that it is formed to move along the formed curved surface. In addition, when the conveyor belt member 161 is formed in this way, the primary roller unit 130 may be installed on the upper portion of the MLCC laminated sheet supply unit 160 to have a sufficient gap through which the MLCC laminated sheet 200 can pass. Of course, even in this case, the primary roller 130 may be installed in a structure that applies pressure downward so that the release tape 220 of the MLCC laminated sheet 200 is attached to the adhesive surface 171 of the adhesive tape 170 . do.

According to the chip separation apparatus 100 according to the embodiments of the present invention shown in FIGS. 3 and 4 having such a structure, the adhesive surface 171 is wound around the tape supply unit 110 so that the adhesive surface 171 faces the outside. The provided adhesive tape 170 is an adhesive tape having a known structure having an adhesive surface 171 having a strong adhesive force on one side and a non-adhesive surface on the other side opposite to the adhesive surface 171, and one end of the tape supply unit ( 110), and the other end thereof is moved through the primary roller 130 and the secondary roller 140 sequentially so that a certain tension is applied while being fixed to the tape recovery unit 120. In the installed state, the tape supply unit 110 and the tape recovery unit 120 rotate in opposite directions, and a certain tension applied to the adhesive tape 170 by controlling the rotation speed of the tape supply unit 110 and the tape recovery unit 120 . In this maintained state, the adhesive tape 170 wound on the tape supply unit 110 is unwound and is operated to be wound on the tape recovery unit 120 . In this continuous operation process, the release tape 220 of the MLCC laminated sheet is attached and moved to the adhesive surface 171 of the adhesive tape 170 by the first roller part 130 and/or the pressing part 180 . Before the adhesive tape 170 is recovered from the secondary roller unit 140 to the tape recovery unit 120, the green chip 210 is automatically separated by the chip separation unit 150, and the adhesive tape 170 is It can be seen that only the release tape 220 can be recovered by the tape recovery unit 120 in the attached state.

Therefore, when the chip separation device of the present invention having the above structure is used, the green chip can be automatically separated from the release tape of the MLCC laminated sheet during MLCC manufacturing, thereby providing an automated MLCC manufacturing system and MLCC manufacturing method. can do.

Although the present invention has been illustrated and described with reference to preferred embodiments as described above, it is not limited to the above-described embodiments, and those of ordinary skill in the art to which the present invention pertains within the scope not departing from the spirit of the present invention Various changes and modifications will be possible.
