Abstract

(57) [Summary] [Object] The present invention relates to a tray for baking an electrode of an electronic component such as a varistor element, and an object thereof is to prevent peeling of the electrode. In order to achieve this object, the present invention provides a plate-shaped body with a plurality of openings 6 for accommodating and holding the electronic component 5, and the lower peripheral edge of the electronic component 5 is provided inside and below the opening 6. A holding portion for holding is formed.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an electrode baking tray for electronic components such as varistor elements.

[0002]

2. Description of the Related Art Electronic components such as varistor elements are provided with electrodes 2 on the upper and lower surfaces of a component body 1 as shown in FIG. After the electrodes 2 are applied to the upper and lower surfaces of the component body 1 and dried, a plurality of the electrodes 2 are arranged on the upper surface of the tray 3 made of a wire mesh as shown in FIG. Has become.

[0003]

A problem with the above structure is that the peeling portion 2 is formed on a part of the electrode 2 as shown in FIG.
That is, a is created. That is, the lower electrode 2
The wire net of the tray 3 and the wire net of the tray 3 are heated and baked in a state of being in contact with each other, and a part of the wire is baked on the wire net. . Then, this invention aims at preventing peeling of an electrode.

[0004]

In order to achieve this object, the present invention provides a plate-shaped body with a plurality of openings for accommodating and holding electronic components, and the inner and lower portions of the openings are provided with the electronic components. A holding portion for holding the lower peripheral edge is formed.

[0005]

With the above structure, since the lower peripheral portion of the electronic component is held by the holding portion of the opening, the lower electrode does not come into contact with the tray, and as a result, the electrode does not peel off. is there.

[0006]

1 and 2, reference numeral 4 denotes a plate-shaped tray made of nickel, for example, and a plurality of openings 6 for accommodating and holding electronic components 5 are provided in this tray. Opening 6
A step 6a is formed inwardly in the lower part of
The step portion 6a is configured to hold the lower peripheral edge of the electronic component 5. That is, as shown in FIG. 2, the electronic component 5 is housed in the opening 6 and held by the step 6a. In this state, electrodes provided by coating and drying the upper and lower surfaces of the electronic component 5 are provided. 7 is baked by heating from the upper and lower surfaces of the opening 6.

Next, FIGS. 3 and 4 show another embodiment of the present invention. In this embodiment, the tray 8 has an opening 9 having an inverted truncated cone shape.
Is provided, and the electronic component 5 is housed and held therein as shown in FIG. In this embodiment, as is clear from FIG. 4, only the lowermost outer circumference of the electronic component 5 comes into contact with the tapered surface of the opening 9, so that the electrode 7 can be made larger than that shown in FIG. . That is, FIG.
Since the step portion 6a must hold the peripheral portion of the lower surface of the electronic component 5 in an appropriate amount, peeling occurs after baking when the electrode 7 contacts the portion, whereas in FIG. 4, only the outermost periphery is held. Therefore, the electrode 7 can be enlarged.

Further, in FIGS. 2 and 4, the openings 6 and 9 are formed.
Since hot air may be blocked up and down by the holding part of the electronic component 5 in this case, at this time, if three cutouts are provided outward at equal intervals of 120 degrees in this holding part, this cutting It becomes possible to smoothly perform the vertical convection of hot air through the notch.

Further, when the heat capacity of the trays 4 and 8 is large and the heating time becomes long, the structure of these tray openings 6 and 9 is left as it is, and other portions are made by laminating upper and lower thin plates. Or, it may be made of mesh.

[0010]

As described above, according to the present invention, a plurality of openings for accommodating and holding electronic components are provided in a plate-like member, and a holding portion for holding the lower peripheral edge of the electronic component is provided in the inner lower portion of the openings. It was formed. Therefore, since the lower peripheral edge of the electronic component is held by the holding portion of the opening, the electrode on the lower surface does not come into contact with the tray, and as a result, the electrode does not peel off.
