- 13 is a conductor formed on the exposed end side of the internal electrode
- 14 is an external electrode.
- the manufacturing method of this laminated ceramic capacitor is as follows. First, a dielectric green sheet (ceramic layer 11) in which a Pd paste (internal electrode 12) is screen-printed is used. ) Is laminated, and then a laminated molded body is produced by press bonding, and cut into chips of a desired size, and then 350 to 400. After degreased with C, they were placed on a Pt mesh and fired in air at 130-135 ° C. Without polishing the obtained sintered body 20, the Ag electrode was baked so as to cover the conductor 13 bulging from the internal electrode 12 to the side surface of the sintered body 20, and the external electrode 14 was baked. Formed.
- a degreased chip was fired under the same temperature conditions as above, using only a porcelain sheath without using a Pt mesh, and The Ag electrode was baked.
- the capacitance is reduced due to a poor connection between the internal electrode 12 and the external electrode 14.
- the defects related to the small amount and the increase in the dielectric loss were less than 1Z1000.
- the failure rate was 20% or more.
- the conductor 23 formed on the exposed end side of the internal electrode 22 after firing is formed on the side surface of the sintered body 20 as shown in FIG. , And are in a state where the electrical connection between the internal electrode 22 and the external electrode 14 can be extremely easily achieved.
- the end face 2a of the internal electrode 2 is fired after firing.
- the largest one is recessed about 10 m from the end face 1 a of the ceramic layer 1, and connection with the internal electrode 2 is not possible even if Ag paste is applied in this state It is thought that things occur frequently.
- the internal electrode 22 containing d as a main component is collected on the protruding end side of the internal electrode 22 to prevent evaporation of Pd, and the supply of Pt further increases the conductor portion 23 from the exposed end side. Bulging inside The exposed end side of the electrode 22 completely protrudes to the side surface of the sintered body 20.
- the conductor 13 containing Pt is formed on the exposed end side of the internal electrode 12 containing Pd as a main component.
- the external electrode 14 is connected via 13.
- an electrode mainly composed of Ag and resin is applied as the external electrode 14 without baking the Ag paste, and the external electrode is dried. Even with the provision of 14, the failure related to the decrease in capacitance and the increase in dielectric loss was 1/10000 or less.
- an experiment was conducted under the same conditions. Failures related to increased dielectric loss amounted to more than 99%.
- the thickness of the internal electrode 12 was reduced from 1.5 / um to 0.8, and the external electrode 14 was baked with an Ag electrode to reduce the capacitance and increase the dielectric loss. As a result, it was found that the value was still 1/1000 or less.
- the thickness of the internal electrode 2 is set to 1.5 ⁇ m and the side surface of the laminated sintered body 3a is By polishing and exposing the internal electrode 2 and then firing the external electrode (not shown), a failure related to a decrease in capacitance and an increase in dielectric loss is reduced to 1/1000 or less. I was able to. However, when the thickness of the internal electrode 2 was set to 0.8 m, the above-mentioned defect increased to 151000. This is because the conventional method of polishing the side surface of the laminated sintered body 3a to expose the internal electrode 2 and then baking the external electrode is as follows. This is thought to be due to a decrease in
- the atmosphere at the time of firing is important.
- the atmosphere at the time of firing is important.
- the oxygen concentration is 100%
- the defect related to the increase in oxygen content decreased to 5 / 100,000, but increased sharply to over 20% in a nitrogen stream with an oxygen concentration of 1%.
- Exposure of internal electrode 22 after firing As a result of observing the conductor portion 23 formed on the end side, in the former case, the amount of protrusion from the side surface of the sintered body 20 was larger than in the case of firing in the air, whereas In the latter case, it was drawn from the side of the sintered body 20.
- FIG. 3 shows the results of an investigation of the weight loss of the Pt mesh used in Example 1 at high temperatures with different oxygen concentrations.
- the amount of evaporated Pt increases when the oxygen concentration is high, but hardly evaporates when the oxygen concentration is low. Therefore, when the oxygen concentration during firing is high, the supply amount of Pt vapor increases, and the conductor portion 23 swells from the exposed end side of the internal electrode 22, but when the oxygen concentration is low, the Pt vapor increases. Since Pd is not supplied, the evaporation of Pd proceeds and the conductor section 23 is not formed from the exposed end side of the internal electrode 22, which is considered to be the cause of the above result.
- a dielectric green sheet (ceramic layer 11) on which a Pd paste (internal electrode 12) is screen-printed is laminated, and then a laminated molded body is produced by press bonding. Cut into chips of desired size and degrease at 350-400 ° C. Separately, a chloroplatinic acid solution equivalent to 20 mg of Pt was added dropwise to 25 ml of zirconia powder having a particle size of about 20 ⁇ m, and the mixture was stirred and dried. Make a near powder.
- This zirconium powder was packed in a porcelain jar while being spread on a chip of degreased equivalent to an apparent volume of 25 m1, and calcined under the same temperature conditions as in Example 1.
- the Ag electrode was baked as 14.
- a degreased chip is dusted with a zirconia powder not carrying Pt, baked under the same temperature conditions as above, and an external electrode is baked.
- firing was performed without using any zirconia powder.
- an electrode mainly composed of Ag and resin is used as the external electrode 14 without burning the Ag paste. Even when the coated and dried external electrodes 14 are provided, the defects related to the decrease in the capacitance and the increase in the dielectric loss are 3Z1000 or less, which is worse than the case of the first embodiment. Has further decreased.
- the cracking failure of the sintered bodies after firing was about 20000 to 3Z10000, but in the case of the second comparative example. In the case of the above, the defect was 15% or more. Therefore, it is understood that spraying the chip with the Pt-supported zirconium powder is effective in terms of both uniform supply of the Pt vapor and prevention of the chips from sticking to each other.
- the failure related to the decrease in the capacitance and the increase in the dielectric loss is 1/100000
- the multilayer ceramic capacitor according to the second embodiment Defects have been further reduced as compared to ceramic capacitors.
- This is made of cylindrical porcelain
- the thermal and atmospheric uniformity during firing is improved by the rotation of the sheath, so that the evaporation of Pt and the supply of Pt vapor to the exposed end side of the internal electrode 12 are uniform. It seems to have been due to the rapid progress. Therefore, the rotation of the cylindrical porcelain sheath is preferably performed in a temperature range not lower than the temperature at which Pt carried on the zirconia powder starts to evaporate.
- an electrode mainly composed of Ag and resin was applied and dried without baking Ag paste as the external electrode 14. Even with the provision of external electrodes, the number of failures related to a decrease in capacitance and an increase in dielectric loss was less than 1,000,000, and the failures were further reduced as compared with the case of Example 2.
- the sticking failure between the sintered bodies after firing was also 1/10000 or less, which was smaller than that of the multilayer ceramic capacitor according to Example 2. This is considered to be due to the fact that the chip was rotated by the rotation of the cylindrical porcelain sheath and fired while receiving an appropriate impact, thereby preventing the sticking.
- the temperature is preferably higher than the temperature at which the mechanical strength of the chip after degreasing starts to increase.
- appearance defects such as chipping and cracking of the sintered body after firing were 1/10000 or less.
- Example 3 the degreased chip and the zirconia powder carrying Pt were placed in a cylindrical porcelain jar having vent holes at both ends and baked while rotating, but were baked in a crucible. It goes without saying that the same effect can be obtained by baking while stirring with a stirring tool such as a user.
- the degreased chip prepared in the same manner as in Example 1 was placed in a cylindrical porcelain hood covered with Pt mesh lids at both ends, and placed in a tubular furnace having a furnace core tube held horizontally. Then, while rotating the sheath at a rate of 0.5 rotations per minute in a high temperature region of 900 ° C. or higher, baking is performed by flowing air under the same temperature conditions as in Example 1, and then externally. An Ag electrode was baked as electrode 14.
- the defect relating to the decrease in the capacitance and the increase in the dielectric loss is 5Z100,000, and the multilayer ceramic capacitor according to the first embodiment is defective. Defects have decreased compared to capacitors. This is thought to be due to the fact that the rotation of the cylindrical porcelain sheath improved the thermal and atmospheric uniformity during firing, as in Example 3.
- an electrode mainly composed of Ag and resin was applied as the external electrode 14 without baking the Ag paste, and the external electrode was dried. Even if electrodes 14 are provided, the failures related to the decrease in capacitance and the increase in dielectric loss The value was 8 Z 100 000, and the number of defects was smaller than in the case of Example 1.
- the sticking failure between the sintered bodies after firing is less than 100,000 or less, such as chipping or cracking of the sintered body after firing.
- the appearance defect was 5 / 100,000, which was higher than that of the multilayer ceramic capacitor according to Example 3.
- Example 4 since the rotation was performed without adding the zirconia powder, it is considered that the cause was an increase in the impact of the rotating sintered bodies.
- Example 4 cylindrical porcelain hoods with Pt mesh lids at both ends were used.However, even when a Pt tube was used in place of the cylindrical porcelain hoods, the inner wall was subjected to Pt plating. It goes without saying that a cylindrical porcelain sheath may be used.
- the internal electrode is a ceramic electronic component having an exposed end on the substrate surface, for example, a multilayer piezoelectric actuator, a multilayer chip collector, a ceramic wiring board, etc. Exactly the same effect is obtained. Furthermore, even if the internal electrode is Pd and the vapor collected on the exposed end side is not Pt, the specific conductor material and the electrode material that selectively collects the vapor of the specific conductor material are used. It is clear that the same effect can be obtained with the combination of.
- the electronic component of the present invention includes a conductor formed by selectively collecting vapor of a conductor material different from that of the internal electrode only on the exposed end side of the internal electrode provided in the base.
- the internal electrode is connected to the external electrode provided on the base via this conductor, and even after the internal electrode is thinned, The electrical connection between the internal electrode and the external electrode can be secured without polishing the side surface of the sintered body.
