DETAILED DESCRIPTION OF THE INVENTION The present invention will be described in the following order.

A. Industrial fields of use B. Overview of the device C. Prior art [Fig. 3] D. Problems to be solved by the device E. Means for solving the problem F. Action G. Example [first 1 and 2] H. Effect of the invention (A. Industrial application field) The invention is a socket holder of an IC handler, especially a measured object.
The present invention relates to an IC handler socket holder to which an IC socket to which an IC is attached is attached by screwing or the like.

(B. Outline of the Invention) In the socket holder of the above IC handler, the present invention has one side surface of the IC socket to prevent the IC socket from being attached to the socket holder quickly and accurately. And a positioning surface against which the side surface of the IC socket at a right angle to the side surface is stopped.

(C. Prior art) [FIG. 3] The ICs that have been manufactured are described in, for example, JP-A-60-34030, JP-A-60-35528, and JP-A-60-154636. The IC handler makes the circuit electrically connected to the inspection circuit and the selection circuit, and the inspection circuit tests the electrical characteristics to discriminate the non-defective product, the defective product, and the grade.

In the IC handler, the electrical connection between the IC to be measured and the inspection circuit is often made via the child socket and the parent socket. The parent socket is a socket directly connected to the inspection circuit, and the child socket attached to the socket holder is attached to this. The IC to be measured is directly attached to the child socket. In this way, the two sockets, the parent socket and the child socket, are interposed between the IC to be measured and the inspection circuit because the IC to be measured is directly attached to the parent socket directly connected to the inspection circuit. In such a case, the receiving portion of the parent socket will be abraded, and it will be very troublesome to replace it because it is electrically connected to the inspection circuit.

By the way, conventionally, the IC socket which is a child socket is attached to a frame-shaped socket holder a as shown in FIG. b and b are IC socket mounting screw holes formed at a pair of diagonally opposite corners of the socket holder a, and the tips of the screws passed through the screw insertion holes of the IC socket are inserted into the screw holes b and b. The IC socket was attached to the socket holder a by screwing.

(D. Problems to be Solved by the Invention) By the way, positioning when mounting the IC socket on the socket holder a shown in FIG. 3 must be done by using a gauge, which is troublesome.

This is because if the IC socket, which is the child socket, is out of position, it becomes impossible to automatically attach the IC under test to the IC socket, and the positioning accuracy of the IC socket must be extremely high. Since there is always a gap between the screw and the screw insertion hole, the positioning accuracy of the IC socket cannot be adjusted to the required height without performing alignment using a gauge. For this positioning, specifically, use a gauge to position the IC socket with a precision of about 0.03 mm in a state where the IC socket before screwing the screw into the screw hole and before tightening can be moved slightly in the horizontal direction. It had to be done in a relatively tedious way of tightening.

The present invention has been made to solve such a problem, and an object of the present invention is to provide a socket holder capable of easily and quickly positioning and mounting an IC socket without using a gauge.

(E. Means for Solving Problems) In order to solve the above-mentioned problems, the socket holder of the IC handler of the present invention has a positioning surface on which one side of the IC socket is fixed and a right angle with the side surface of the IC socket It is characterized in that a side surface of is formed with a positioning surface to be stopped.

(F. Action) According to the socket holder of the IC handler of the present invention, one side of the IC socket is placed on one positioning surface of the socket holder, and the other side of the IC socket which is perpendicular to the above side is positioned on the other side of the socket holder. The IC socket can be positioned with respect to the socket holder simply by touching the surface. And by screwing etc. in that state
The IC socket can be attached to the socket holder easily and accurately.
