Abstract

(57) [Summary] [Structure] The marks to be attached to electronic parts are composed of a large-diameter shallow bottom and a small-diameter deep bottom to double the amount of information that can be displayed with one mark. Then, the area to be marked is halved,
The area where no mark is attached can be a flat suction area. [Effect] Since the suction area is flat, when the suction jig vacuum-sucks the surface of the suction area, air does not flow into the suction jig and the suction force does not decrease, so the electronic component is securely vacuum-sucked. It

Description

[Detailed description of the device]

[0001]

[Industrial application]

 The present invention relates to an electronic component in which a product type or the like is indicated by attaching a plurality of marks on the surface, and more specifically, to an electronic component in which a mark is attached so as to ensure vacuum suction.

[0002]

[Prior Art]

 Mold type electronic parts have a mark on the surface that indicates the type of product. If the electronic component has a size of 7 mm or 4.5 mm, the standard and the manufacturing time can be displayed on the surface by a combination of numbers and letters.

However, when the size of electronic parts is reduced to 1.3 mm × 0.8 mm due to the demand for high-density mounting, numbers and characters cannot be displayed on the surface of the electronic parts. As shown in 4, the mark (1) is attached by laser marking to indicate the type and the like. The mark (1) forms a minute recess on the surface (2) of the electronic component as shown in Fig. 5, and "Yes" or "None" of the mark (1), that is, the product type is displayed by the binary system. It Since the electronic components are miniaturized, the mark (1) may be attached on almost the entire surface. However, the polarity of the electronic component can be determined by forming the end portion (3) without the mark (1).

[0004]

[Problems to be solved by the device]

 The electronic component is mounted by vacuum-sucking the surface (2) on which the mark (1) is attached by a suction jig (not shown). However, since the mark (1) forms a minute depression on the surface (2), if the mark (1) is attached to almost the entire surface of the electronic component, the mark (1) where the suction jig is depressed As a result, air may flow into the suction jig from the recessed mark (1) and the suction force may decrease, resulting in a suction failure.

Therefore, an object of the present invention is to provide an electronic component in which even a laser-printed surface can be securely vacuum-adsorbed without air leakage.

[0006]

[Means for Solving the Problems]

 In order to achieve the above object, the present invention provides an electronic component having a plurality of marks for displaying various information on the surface to be attracted, in which a mark composed of a large-diameter shallow bottom and a small-diameter deep bottom is provided outside the adsorption area. It is attached to.

It is also possible to attach the mark to one side of the surface and use the opposite side as an adsorption area.

Further, the mark may be attached to the peripheral portion of the surface so that the intermediate portion serves as a suction area.

[0009]

[Action]

 By configuring the mark with a large-diameter shallow bottom and a small-diameter deep bottom, it is possible to display a large amount of information with one mark, reducing the area to be marked, and the unmarked area. Is the adsorption area. Since this suction area is flat, air does not flow into the suction jig that sucks the suction area, and the electronic component is reliably vacuum-sucked.

[0010]

【Example】

 A first embodiment of the present invention will be described with reference to FIGS. However, the same parts as those of the conventional one are designated by the same reference numerals and the description thereof will be omitted.

In the electronic component according to the first embodiment, as shown in FIG. 1, a mark (10) indicating a type or the like is attached to one side of the surface (2) by a laser, and the mark (10) is not attached. The opposite side is the adsorption area (20). The mark (10) is composed of a large diameter shallow bottom portion (11) and a small diameter deep bottom portion (12) as shown in FIG. According to one mark (10), when the mark (10) is not attached, only the large diameter shallow bottom (11) is formed, only the small diameter deep bottom (12) is formed, and the large diameter It is possible to display four types of information when both the shallow bottom portion (11) and the small diameter deep bottom portion (12) are formed. Therefore, in the past, one mark (1) could display only two types of information, "marked" (1) is "present" or "not marked", but the mark (10) of this electronic component has 4 types of information. Since the information can be displayed, the area where the mark (10) is displayed can be halved, and the area where the mark (10) is not displayed can be the adsorption area (20).

Since the suction area (20) has no depression and is flat, when the suction jig (not shown) sucks the suction area (20), the suction area (20) is sucked from the surface (2) of the electronic component. Since air does not flow into the jig and the suction force does not decrease, electronic components are reliably vacuum-sucked.

Since the surface (2) of the electronic component is divided into a mark-displayed region and a suction region (20), the polarity of the electronic component is divided into the mark-displayed region and the suction region (20). Can be determined.

In the electronic component according to the second embodiment, as shown in FIG. 3, the mark (10) is attached to the peripheral portion of the surface, and the intermediate portion of the surface is used as the suction area (20). If the mark (10) is attached to the periphery of the electronic component, it is difficult to determine the polarity, so it is preferable to attach the mark (10) for displaying the polarity separately or to apply to the electronic component having no polarity.

[0015]

[Effect of the device]

 According to the present invention, by attaching a mark composed of a large-diameter shallow bottom and a small-diameter deep bottom to the surface, it is possible to form a flat adsorption area on the surface so that air does not flow into the adsorption jig. Therefore, the electronic components are securely sucked and the suction error is eliminated. Therefore, the workability of mounting the electronic component is improved, and the productivity is improved.
