Hereinafter, the present invention will be described in detail with reference to the accompanying drawings.

The present invention relates to an insert, and more particularly, to an insert on which a semiconductor device is mounted, a latch portion moving between a position for pressing and supporting an upper surface of a semiconductor device accommodated in the insert and a position for opening an upper surface space of the semiconductor device. (2), a latch mechanism (7) for moving the latch portion (2) between the two positions, an insert body (10) having a mounting frame opening (8) inside the body, and a semiconductor device seating opening therein (12) having an outer surface corresponding to the mounting frame opening (8) and a slide guide (14) inclined to the seating opening (12) and having a protrusion (16) inserted into the mounting frame opening (8). Mounting frame 20; A ball guide 40 supporting the semiconductor device at a lower end of the mounting opening 12 of the mounting frame 20; And a coupling block 50 coupled to the bottom of the insert body and configured to engage the mounting frame 20 in the vertical direction so as to have a clearance with the insert body 10.

Specific examples thereof are as shown in FIGS. 1 to 3. That is, the insert of the present invention is combined with the insert body 10, the mounting frame 20 inserted into and embedded in the insert body, and the ball guide 40 coupled to the lower end of the seating opening of the mounting frame, and the insert body 10. It consists of a coupling block 50 for mediating the coupling of the mounting frame 20 and the insert body 10. The insert body 10 includes a latch mechanism 7 for forming a conventional latch portion 2 and an operation thereof, and an opening 8 for a mounting frame for receiving the mounting frame 20 as an opening therein. Has

The latch mechanism 7 may be applied to a variety of known latch mechanisms and latches applied to a conventional insert. Preferably, the latch mechanism 7 is rotatably installed to face the upper portion of the insert body 10. Rotating bar (3) and integrally with the rotary bar (3) extending from the opposite end to the middle of the opening for the mounting frame (8) and close and spaced up and down relative to the insert body (10) A rotary drive part 4 fixed to the insert body 10 by the drive body 30 (for example, a push plate) to the insert body 10 so as to rotate in response to the operation of the drive body 30 in the proximal direction; It includes a pair of symmetrical, including a latch elastic member 6 for applying a force in the spaced direction of the drive body 30 to the end of the drive unit 4, the latch unit 2 is the rotary bar (3) In the middle of the rotary bar 3 integrally with the From may be of a rod shape extending to be symmetrical to each other toward the center. Here, the rotary bar 3 is rotatably fixed so as to drive the latch unit 2 opposite to each other as shown in the insert body as shown, the end of the push plate (drive) A driving body which extends to the middle of the opening for the mounting frame in an opposite direction from both ends integrally with the rotating bar so that the rotating bar can rotate when the rotating bar is rotated, and close and spaced up and down with respect to the insert body. And a rotation driving part pivotally fixed to the insert body so as to rotate in response to the operation of the driving body (push plate or pusher) from the push plate or pusher). As a specific example of this, as shown in the drawing, an intermediate portion of the rotary driving unit is pivotally fixed to the wall of the insert body so that the rotary bar rotates when the end of the rotary driving unit is pressed by the driving unit. In addition, since the rotary drive unit is required to be restored after rotating the rotary bar, the latch elastic member is coupled as described above. The latch elastic member serves to apply a force to the end of the rotational drive in the direction of the separation (pushing direction) of the drive body. To this end, as shown a specific example, it is possible to allow the latch elastic member to be coupled to the end of the rotational drive, which is preferably applied to the spring as shown in consideration of ease of manufacture and elasticity and robustness. .

In addition, the latch portion (2) is a rod shape symmetrically extending from each other to the center side from the middle of the rotation bar integrally with the rotation bar when the latch mechanism is composed of a rotation bar, a rotation driving portion and an elastic member as described above It can be configured as. Accordingly, the latch unit is moved between the position where the upper surface of the semiconductor device accommodated in the insert is supported by the rotation of the rotation bar and the position where the upper space of the upper surface of the semiconductor device is opened, thereby mounting the semiconductor device on the insert. In the case where the semiconductor device upper surface space is opened, and when the semiconductor device is mounted and accommodated, the semiconductor device is located in a position where the upper surface of the semiconductor device accommodated in the insert is pressed and supported, and the semiconductor device is removed from the insert again. In this case, the semiconductor device may be driven to be positioned at an open position of the upper surface of the semiconductor device.

The mounting frame 20 coupled to the insert body 10 is a portion in which the semiconductor device is actually mounted. The overall shape has the semiconductor device seating opening 12 therein, and the mounting frame opening 8 is formed therein. It has an outer surface corresponding to and a slide guide 14 inclined to the seating opening 12 and a protrusion 16 inserted into the mounting frame opening 8.

The mounting frame 20 is coupled to have a gap in the insert body 10 via a pair of coupling blocks 50 on both sides, the coupling block 50 is fixed means (for example, such as rivets or bolts It includes a conventional fixing means, and is commonly referred to as rivets) fixedly coupled to the insert body.

That is, as shown, the insert according to the present invention has a seating opening having a configuration of a portion in which a semiconductor device is seated in a conventional insert, and is coupled with the insert body with a clearance so that movement to the side of the mounting frame is prevented. The protrusion has a configuration in which the protrusion is inserted into and coupled to the opening 8 for the mounting frame. Through this, it is possible to reduce the stress applied to the rivet and the like, to obtain an effect of more easily aligning with the main body, and to allow the fine motion in the play to be limited in the design range. Therefore, the outer surface of the protrusion has a shape corresponding to the opening for the mounting frame of the main body. It is not necessary here to necessarily have the same shape as the opening for the mounting frame, it is necessary to guide the insertion of the mounting frame into the opening, so that only limited movement to the side of the mounting frame.

The protrusion also has a slide guide 14 inclined to the seating opening to guide the semiconductor device to be mounted as shown in the seating opening. Preferably, the slide guides are present at each of the front, rear, left, and right sides of the seating opening as shown, and more preferably, at least two or more of the slide guides are arranged in parallel with respect to each surface as shown. It is advantageous because it is advantageous in guiding this.

The mounting frame 20 is inserted into the insert body as described through the coupling block 50 to enable vertical movement on the coupling block 50, the coupling block 50 is inserted into the insert body 10 Fix with rivet and up and down direction. The mounting frame 20 can be moved up and down and sideways on the coupling block 50, so that even a slight misalignment can be alleviated in the insert, the buffer and the buffer to the impact of the handler insert and device Can be prevented in advance. To this end, it may include an elastic member 19 that is elastically deformed in the vertical direction between the mounting frame 20 and the coupling block 50, there can be used a variety of known elastic members, including coil springs According to such a configuration, fine movement of the mounting frame 20 can be made in a controllable form, and can effectively play a buffer role against the impact of the handler.

The insert of the present invention has a closed loop ball guide that surrounds at least one of the ball terminals. In this case, a plurality of ball terminal bundles or one ball terminal are guided through a loop, and thus the guide is made in four directions. For each gap, there can be a wider gap, preventing jams and more flexible tolerances.

That is, as shown in Figure 2, the ball guide 40 forms a closed loop corresponding to the ball terminal of the semiconductor device to induce the seating of the ball terminal and the accurate mounting of the semiconductor device. Since the ball guide should guide the mounting of the semiconductor chip package, the ball guide extends into the opening so as to correspond to the ball terminal in the seating opening of the insert body, and is coupled to the seating opening. The ball guide is assembled in the seating opening of the insert body to be combined (removably coupled to allow other ball guides to be combined and used according to the arrangement of the ball terminals, or to be separated so as not to be detached once combined). Alternatively, it may be configured integrally with the insert body (may be configured integrally at the time of manufacture), and may be configured as a dedicated insert for a certain ball terminal arrangement. The ball guide may form a closed loop surrounding at least one of the ball terminals of the semiconductor device so as to correspond to the ball terminal. The material of the loop is made of an insulator for electrical insulation with the ball terminal, and preferably for the ease of contact with the semiconductor device, a loop having a hole formed in a flat plate.
