no. 1 Embodiment approach

[0048] Overall Configuration of Multilayer Ceramic Capacitors

[0049] First, as one embodiment of the electronic component according to the present invention, the overall configuration of a multilayer ceramic capacitor will be described.

[0050] Such as figure 1 As shown, the multilayer ceramic capacitor 2 according to this embodiment has a capacitor base 4 , a first terminal electrode 6 , and a second terminal electrode 8 . The capacitor base 4 has dielectric layers 10 and internal electrode layers 12 , and these internal electrode layers 12 are alternately laminated between the dielectric layers 10 . One internal electrode layer 12 stacked alternately is electrically connected to the inner side of the first terminal electrode 6 formed on the outer side of one end portion of the capacitor element 4 . In addition, the alternately stacked other internal electrode layers 12 are electrically connected to the inner side of the second terminal electrode 8 formed on the outer s...

no. 2 Embodiment approach

[0155] In this embodiment, if Figure 6 shown. Inside the drying chamber 62 , a roller conveyor 80 is disposed instead of the metal plate 84 over the length L1 from the entrance 62 a to a predetermined range. Compared with the belt conveyor 82, the roller conveyor 80 has less contact with the sheet 20, and uneven drying is less likely to occur. The above facts were confirmed by the experiments of the present inventors. Other structures and effects are the same as those in Embodiment 1.

no. 3 Embodiment approach

[0157] In addition, the present invention can also be as follows Figure 7 constructed as shown. In this embodiment, inside the drying chamber 62 , a roller conveyor 80 is provided in the longitudinal direction below the sheet 20 instead of the belt conveyor 82 to guide the sheet 20 to be conveyed in the continuous conveyance direction Dc.

[0158] Especially in this embodiment, not all the roller conveyors 80 inside the drying chamber 62 are in contact with the back surface of the sheet 20 . In a predetermined range length L1 from the entrance 62 a of the drying chamber 62 to the conveyance direction Dc, the roller conveyor 80 is positioned one step lower than the other roller conveyors 80 so as not to contact the sheet 20 . Alternatively, the roller conveyor 80 may not exist at all within the range length L1. This embodiment can further suppress drying unevenness. Other configurations and effects are the same as those of the first embodiment.

Abstract

A printing and drying method comprising laying a support sheet 20 elongated in the long direction so as to bridge both a printing zone 42 and a drying zone 44 , in the printing zone 42 , giving the support sheet 20 a first tension F 1 , in that state, printing the support sheet 20 with predetermined patterns, then feeding the support sheet 20 toward the drying zone 44 , in the drying zone 44 , giving the support sheet 20 on which the predetermined patterns were printed a second tension F 2 , and in that state, drying it in a drying chamber 62 . The first tension F 1 and the second tension F 2are given by separate tension giving means, and the second tension F 2 is tension given along the support sheet 20 in the long direction and able to prevent shrinkage of the support sheet 20 in the long direction while passing through the drying zone 44.

Description

technical field [0001] The present invention relates to a printing and drying method, a method for manufacturing electronic components, and a printing and drying device. More specifically, it relates to a method capable of repeatedly printing complementary patterns with little positional displacement on a support sheet when manufacturing electronic components such as laminated ceramic capacitors, for example. A printing drying method and a printing drying device. Background technique [0002] For example, when manufacturing electronic components such as multilayer ceramic capacitors, such as Figure 10 As shown, sometimes a release layer 22 is formed on the surface of a carrier sheet 20 as a support sheet, and then an electrode layer 12a of a predetermined pattern is formed on the release layer by printing. Alternatively, a ceramic green sheet may be formed on the surface of the carrier sheet 20, and then the electrode layer 12a of a predetermined pattern is formed on the su...
