A probe card device and a dual-arm probe are provided. The dual-arm probe has a probe length, and includes a bifurcation end portion and a testing end portion. The dual-arm probe has two broad side surfaces respectively arranged on two opposite sides thereof. The dual-arm probe has a separation slot that is recessed from a bifurcation opening of the bifurcation end portion toward the testing end portion and that penetrates from one of the two broad side surfaces to the other one, so that two branch arms of the dual-arm probe are defined by the separation slot and are spaced apart from each other. The separation slot has a slot length being 50% to 90% of the probe length. In a cross section of the two branch arms, an area of any one of the two branch arms is 90% to 110% of that of the other one.

This application claims the benefit of priority to Taiwan Patent Application No. 109142031, filed on Nov. 30, 2020. The entire content of the above identified application is incorporated herein by reference.
Some references, which may include patents, patent applications and various publications, may be cited and discussed in the description of this disclosure. The citation and/or discussion of such references is provided merely to clarify the description of the present disclosure and is not an admission that any such reference is “prior art” to the disclosure described herein. All references cited and discussed in this specification are incorporated herein by reference in their entireties and to the same extent as if each reference was individually incorporated by reference.
The present disclosure relates to a probe card, and more particularly to a probe card device and a dual-arm probe.
The described embodiments may be better understood by reference to the following description and the accompanying drawings, in which:
FIG. 1 is a cross-sectional view of a probe card device according to a first embodiment of the present disclosure;
FIG. 2 is a cross-sectional view showing the probe card device of FIG. 1 when a first guiding board unit and a second guiding board unit are in a staggered arrangement;
The present disclosure is more particularly described in the following examples that are intended as illustrative only since numerous modifications and variations therein will be apparent to those skilled in the art. Like numbers in the drawings indicate like components throughout the views. As used in the description herein and throughout the claims that follow, unless the context clearly dictates otherwise, the meaning of “a”, “an”, and “the” includes plural reference, and the meaning of “in” includes “in” and “on”. Titles or subtitles can be used herein for the convenience of a reader, which shall have no influence on the scope of the present disclosure.
The terms used herein generally have their ordinary meanings in the art. In the case of conflict, the present document, including any definitions given herein, will prevail. The same thing can be expressed in more than one way. Alternative language and synonyms can be used for any term(s) discussed herein, and no special significance is to be placed upon whether a term is elaborated or discussed herein. A recital of one or more synonyms does not exclude the use of other synonyms. The use of examples anywhere in this specification including examples of any terms is illustrative only, and in no way limits the scope and meaning of the present disclosure or of any exemplified term. Likewise, the present disclosure is not limited to various embodiments given herein. Numbering terms such as “first”, “second” or “third” can be used to describe various components, signals or the like, which are for distinguishing one component/signal from another one only, and are not intended to, nor should be construed to impose any substantive limitations on the components, signals or the like.
Referring to FIG. 1 to FIG. 8, a first embodiment of the present disclosure provides a probe card device 1000. As shown in FIG. 1 and FIG. 2, the probe card device 1000 includes a probe head 100 and a space transformer 200 that is connected to one side of the probe head 100 (e.g., a top side of the probe head 100 shown in FIG. 1). Another side of the probe head 100 (e.g., a bottom side of the probe head 100 shown in FIG. 1) is configured to abut against a device under test (DUT) (e.g., a semiconductor wafer that is not shown in the drawings).
