- the present invention relates to a method for manufacturing a laminated ceramic electronic component, which can produce a multilayer ceramic electronic component by laminating a laminate cut.
- Multilayer ceramic electronic devices represented by multilayer ceramic capacitors.
- a binder such as acrylic resin and petital resin, and phthalates, glycols, adipic acid, and phosphate esters
- a dielectric paste is prepared by mixing and dispersing a plasticizer, such as benzene, and an organic solvent, such as toluene, methyl ethyl ketone, and acetone.
- the dielectric paste is applied to a support sheet formed of polyethylene terephthalate (PET) or polypropylene (PP) using an ETAS trusion coater and a gravure coater, and heated to form a coating film. After drying, a ceramic green sheet is prepared.
- PET polyethylene terephthalate
- PP polypropylene
- an electrode paste such as nickel paste is printed on a ceramic green sheet in a predetermined pattern by a screen printing machine or the like, and dried to form an electrode layer.
- the ceramic green screen on which the electrode layer is formed The laminate is peeled from the support sheet to form a laminate unit including the ceramic dust sheet and the electrode layer, and a desired number of laminate cuts are laminated and pressed to obtain a laminate. Is cut into chips to produce a green chip.
- the binder is removed from the green chip, the green chip is fired, and external electrodes are formed, thereby producing a multilayer ceramic electronic component such as a multilayer ceramic capacitor.
- the thickness of the ceramic green sheet that determines the interlayer thickness of the multilayer ceramic capacitor be 3 ⁇ m or 2 ⁇ m or less. It is required to laminate a laminate unit including at least 300 ceramic green sheets and an electrode layer.
- the laminate laminated first on the outer layer is formed. Since the cutout is pressurized more than 300 times and is easily damaged, the stacked units are stacked, for example, 50 sheets at a time, and a plurality of stacked blocks are used. It is necessary to form and laminate a plurality of multilayer blocks on the outer layer of the multilayer ceramic capacitor. .
- the outer layer is fixed on a mold and the multilayer unit is stacked.
- the laminated units including the ceramic green sheets and the electrode layers are fixed on a mold, and the laminated units are laminated. There was a problem that the body unit was likely to be damaged. Disclosure of the invention
- the present invention efficiently prevents a laminate unit including a ceramic green sheet and an electrode layer from being damaged, and efficiently and desirably produces a desired number of products. It is an object of the present invention to provide a method for manufacturing a multilayer ceramic electronic component by which a multilayer ceramic electronic component can be manufactured by stacking layered units.
- An object of the present invention is to provide a method for manufacturing a multilayer ceramic electronic component by laminating a plurality of laminates in which a ceramic green sheet, an electrode layer, and a release layer are laminated in this order on a support sheet. And wherein the adhesive strength between the support and the support sheet is higher than the adhesive strength between the support sheet and the ceramic Darrieen sheet and lower than the adhesive strength between the support sheet and the release layer. Positioning the laminate unit so that the surface of the release layer of the laminate unit comes into contact with the surface of the adhesive layer formed on the surface of the support; Further, the present invention is achieved by a method for manufacturing a laminated ceramic electronic component, which comprises laminating the laminate unit.
- a ceramic green sheet, an electrode layer, and a release layer are laminated on a support sheet in this order.
- the laminated unit is laminated in this order, and the adhesive strength between the support and the support sheet is reduced.
- the laminate unit is formed on the surface of the adhesive layer formed on the surface of the support so that the adhesive strength between the ceramic green sheet and the release layer is lower than the adhesive strength between the ceramic green sheet and the release layer. It is configured so that the surface of the release layer of the substrate is positioned so that the surface of the release layer comes into contact with the substrate, the pressure is applied, and the layer is laminated on the support, so that a desired number of laminated units are laminated and laminated.
- the adhesive layer is formed on the surface of the support such that the adhesive strength between the support and the support is higher than the adhesive strength between the support sheet and the ceramic green sheet. Therefore, the support sheet 1 can be easily peeled off from the ceramic dust sheet of the laminate unit stacked on the support, and the ceramic of the laminate unit stacked on the support can be easily peeled off. It is possible to efficiently stack new laminate units on green sheets. Further, according to the present invention, the adhesive layer is formed on the surface of the support such that the adhesive strength between the adhesive and the support is lower than the adhesive strength between the adhesive layer and the release layer.
- the laminate unit having the adhesive layer formed on the surface of the release layer is placed on the support.
- the step of laminating the ceramic green sheet of the laminated unit unit laminated on the adhesive layer through the adhesive layer is repeated, and a predetermined number of laminated units are laminated on the support.
- the laminated block is laminated on the outer layer of the laminated ceramic capacitor, only the support can be peeled off from the ceramic green sheet while the adhesive layer remains adhered to the release layer. Therefore, it is not necessary to form an adhesive layer on a new laminated block when a new laminated block is laminated on a laminated block laminated on an outer layer or the like, which is efficient.
- the dielectric paste used to form the ceramic green sheet is usually prepared by kneading a dielectric material and an organic vehicle in which a binder is dissolved in an organic solvent.
- the dielectric material is appropriately selected from complex oxides and various compounds to be oxides, for example, carbonates, nitrates, hydroxides, organometallic compounds, etc., and can be used by mixing them. .
- the dielectric material is usually used as a powder having an average particle diameter of about 0.1 ⁇ to about 3.0 ⁇ m.
- the particle size of the dielectric material is preferably smaller than the thickness of the ceramic green sheet.
- the binder used for the organic vehicle is not particularly limited, and various ordinary binders such as ethyl cellulose, polybutyral, and acrylic resin can be used.However, in order to reduce the thickness of the ceramic Darin sheet. For this, a petal-based resin such as polyvinyl butyral is preferably used.
- the organic solvent used in the organic vehicle is not particularly limited, but may be terbineol, butyl carbitol, acetone, or toluene. Any organic solvent is used.
- the dielectric paste can also be produced by kneading a dielectric material and a vehicle in which a water-soluble binder is dissolved in water.
- the water-soluble binder is not particularly limited, and polyvinyl alcohol, methinoresorenose, hydroxysechinoresenorelose, water-soluble acrylic resin, emulsion, etc. are used.
- each component in the dielectric paste are not intended to be particularly limited, for example, a binder of about 1 weight percent to about 5 weight / 0, about 1 0 wt% to about 5 0 percent by weight of the solvent
- the dielectric paste can be prepared so as to include '.
- the dielectric paste may contain additives selected from various dispersants, plasticizers, dielectrics, subcomponent compounds, glass frit, insulators and the like.
- the total content is desirably about 10% by weight or less.
- the content of the plasticizer is preferably about 25 parts by weight to about 100 parts by weight based on 100 parts by weight of the binder resin. If the amount of the plasticizer is too small, the formed ceramic green sheet tends to be brittle. If the amount is too large, the plasticizer oozes out and handling becomes difficult, which is not preferable.
