Abstract

The objective of the present invention is to provide a test device capable of indicating whether a test target element is normal or defective through color light output from a light-emitting unit. To this end, the test device according to the present invention comprises a case having a slot for fastening a test target element, a test board mounted on the case, and a light-emitting unit mounted on the case that outputs at least one of two color lights. The test board comprises a test unit that performs a test on the test target element, a current control unit that controls the amount of current flowing through the light-emitting unit, and a main control unit that generates a control voltage corresponding to a judgment result transmitted from the test unit and transmits it to the current control unit.

Description

Test Apparatus The present invention relates to a test device for testing the characteristics of a test target device. A test device is used to test the performance of memory devices or semiconductor components. A memory device or semiconductor component tested by a test device is called a test target component. The test device can generate various types of test patterns and transmit them to the device under test, analyze the patterns and various signals received from the device under test to analyze the performance of the device under test, and provide the analysis results to the user. In this case, at least two test target devices can be tested simultaneously on a test device, and thus, analysis results for at least two test target devices can be provided simultaneously. However, it is difficult to easily verify the test results, for example, whether the test subjects are normal or defective, on the test device. Therefore, when the test subjects are collected from the test device after the test is completed, test subjects determined to be normal and test subjects determined to be defective may be mixed. Consequently, a rapid response to test subjects determined to be defective may not be possible. FIG. 1 is an exemplary diagram showing the configuration of a test device according to the present invention. FIGS. 2 and FIGS. 3 are exemplary diagrams showing the external structure of a test device according to the present invention. FIG. 4 is an exemplary diagram showing the internal structure of a test device according to the present invention. FIG. 5 is an example diagram showing the structure of the current control unit illustrated in FIG. 4. Throughout the specification, identical reference numbers denote substantially identical components. In the following description, detailed descriptions of components and functions known in the art may be omitted if they are not related to the core components of the invention. The meanings of the terms described in this specification should be understood as follows. The advantages and features of the present invention and the methods for achieving them will become clear by referring to the embodiments described below in detail together with the accompanying drawings. However, the present invention is not limited to the embodiments disclosed below but may be implemented in various different forms. These embodiments are provided merely to ensure that the disclosure of the present invention is complete and to fully inform those skilled in the art of the scope of the invention, and the present invention is defined only by the scope of the claims. The shapes, sizes, ratios, angles, numbers, etc. disclosed in the drawings for explaining embodiments of the present invention are exemplary, and therefore the present invention is not limited to the depicted details. Throughout the specification, the same reference numerals refer to the same components. Furthermore, in describing the present invention, if it is determined that a detailed description of related known technology may unnecessarily obscure the essence of the present invention, such detailed description is omitted. Where terms such as 'comprising,' 'having,' 'consisting of,' etc. are used in this specification, other parts may be added unless 'only' is used. Where a component is expressed in the singular, it includes cases where it is included in the plural unless specifically stated otherwise. In interpreting the components, they are interpreted to include a margin of error even in the absence of a separate explicit statement. In the case of describing a positional relationship, for example, when the positional relationship between two parts is described using expressions such as 'on,' 'upper,' 'lower,' or 'next to,' one or more other parts may be located between the two parts unless 'immediately' or 'directly' is used. In the case of an explanation of a temporal relationship, for example, when a temporal sequence is explained using 'after', 'following', 'next', 'before', etc., it may include cases where the sequence is not continuous unless 'immediately' or 'directly' is used. Although terms such as "first," "second," etc. are used to describe various components, these components are not limited by these terms. These terms are used merely to distinguish one component from another. Accordingly, the first component mentioned below may be the second component within the technical scope of the present invention. "X-axis direction," "Y-axis direction," and "Z-axis direction" should not be interpreted solely as geometric relationships in which the relationship between them is perpendicular, but may mean having a broader directionality within the range in which the configuration of the present invention can function functionally. The term “at least one” should be understood to include all combinations that can be presented from one or more related items. For example, the meaning of “at least one of the first item, the se
