Field of the Invention The present invention relates to a device for testing a shear force of a semiconductor package lead, and more particularly to a device for testing a shear force of a semiconductor package lead for measuring a bonding force between a lead- will be.

2. Description of the Related Art In recent years, a semiconductor package including a semiconductor device that stores vast amounts of data and processes data stored within a short time has been developed.

The semiconductor package includes a semiconductor chip manufacturing process for forming a semiconductor chip by integrating elements such as transistors, resistors, capacitors, and the like on a wafer, a die sorting process for testing a good semiconductor chip by inspecting electrical characteristics of the semiconductor chip, And is fabricated by a packaging process in which a semiconductor chip, which is individualized and electrically connected to an external circuit board or the like, and which is weak in embrittlement is protected from impact / vibration applied from the outside.

The semiconductor package as described above is also commonly referred to as a package lead. The package lead includes a printed circuit board (PCB) and a lead, and the printed circuit board and the lead are overlapped Are bonded to each other by a bonding material such as an epoxy or a double-sided tape excellent in bonding strength.

Since the bonding force between the printed circuit board and the lead is an important factor directly related to the durability of the semiconductor package lead, it is necessary to measure the bonding force of the semiconductor package lead.

Shear force test is effective to measure the bond strength of package leads. However, since the device for performing shear force test has not been provided so far, We are conducting a test.

In order to perform the pull test, first, the substrate jig is bonded to the printed circuit board side of the package lead using a bonding material such as epoxy or tape, and the lead jig is bonded to the lead side using the bonding material as described above.

When the substrate jig and the lead jig are firstly bonded to the printed circuit board and the lead, they are put into a high-temperature oven and subjected to a hardening process for a certain period of time, thereby increasing the bonding force.

After the substrate jig and the lead jig are completely bonded to the printed circuit board and the lead through the oven insertion, the substrate jig and the lead jig are connected to the predetermined pull test device and pulled in opposite directions to each other, Is measured.

However, in the pull test of the package leads as described above, not only the substrate jig and the lead jig need to be primarily bonded to the printed circuit board and the lead, but also must be put in a separate oven and heated. Which is inconvenient and time consuming.

In addition, since the bonding material is bonded not only between the printed circuit board and the leads but also the substrate jig and the lead jig, it is difficult to measure only the bonding force between the printed circuit board and the leads. have.

In addition, once the pull test is completed, the PCB jig and the lead jig, which are respectively bonded to the printed circuit board and the leads, must be removed for recycling, and the operation of removing the bonded substrate jig and lead jig is also very inconvenient and time consuming .

An apparatus for testing a shear force of a semiconductor package lead according to an embodiment of the present invention will be described with reference to Figs.

FIG. 1 is an exploded perspective view showing a device for testing a shear force of a semiconductor package lead according to an embodiment of the present invention, FIG. 2 is an assembled perspective view of FIG. 1, Fig.

As shown in FIGS. 1 and 2, the device for testing a sheathing force for semiconductor package leads according to the present embodiment may include a first housing unit 100 and a second housing unit 200.

The first housing unit 100 is configured to receive an external force in any one direction through an external force providing means such as a load cell. In the first housing unit 100, one of the package leads 10 And a front end block 130 to which an end portion of the front end block is attached.

The package lead 10 is formed by overlapping and bonding the printed circuit board 11 and the lead 12 so as to form layers. The package lead 10 is connected to the package lead 10 (That is, a layer of the printed circuit board 11 or a layer of the lead 12).

3, a layer of the printed circuit board 11 of the package lead 10 is laid on the front end block 130 so that the layer of the lead 12 is caught by the front end block 130 as required. It is acceptable to be placed.

However, it is important that the front end block 130 should be laid so that only one layer of the package leads 10 is laid. If the two layers are laid all together, the printed circuit board 11 and the lid 12 The shear force test of the package lead 10 is impossible.

Here, the first housing unit 100 may include a first housing body 110 and a test bed 120 as shown in FIG.

The first housing unit 110 may include a first horizontal unit 111 and a first vertical unit 112. The first horizontal unit 111 and the first vertical unit 112 may be referred to as " It does not mean that the horizontal part is necessarily arranged horizontally and the vertical part is necessarily arranged vertically.

The first vertical part 112 is formed to be bent from the first horizontal part 111 and a first receiving groove 113 having a predetermined size is formed below the first vertical part 112.

The first horizontal portion 111 and the first vertical portion 112 are preferably bent at right angles, but the angle of bending is not necessarily limited to this, and may be changed according to the needs of the practitioner.

The test bed 120 is coupled to the first receiving groove 113 and is detachably coupled to the first housing body 110 through a conventional coupling means such as a bolt And the front end block 130 is coupled to a lower portion of the test bed 120.

The front end block 130 protrudes from the one side of the test bed 120 toward the second housing unit 200 by a predetermined length. The protrusion amount of the front end block 130 is larger than the protrusion amount of the package lead 10 ) Is related to the thickness of one layer.

3, when the printed circuit board 11 layer of the package lead 10 is arranged to be caught by the front end block 130, the front end block 130 is connected to the printed circuit board 11 ) Layer, the amount of protrusion must be set. This is to prevent both the printed circuit board 11 layer and the lead 12 layer from being caught by the front end block 130 as described above.

It is preferable that the amount of protrusion of the front end block 130 is set to be adjustable according to the thickness of each layer constituting the package lead 10 because the thickness of each layer The protruding amount of the front end block 130 may be adjusted to actively test even in this case as well.

The amount of protrusion of the front end block 130 can be adjusted through the elongated hole formed at the lower end of the test bed 120 to which the front end block 130 is coupled and the bolt. Adjusting the amount of protrusion of the front end block 130 through the holes and bolts described herein is generally well known and is expected to be easily carried out by those skilled in the art, so that separate drawings and explanations are omitted.

In addition, the first housing unit 100 may be provided with a second housing unit 200, which is opposed to the second housing unit 200, so that the first housing unit 100 can move more stably along a predetermined path when the first housing unit 100 receives external force in one direction. It is preferable that a first guide member 140 for guiding movement is provided.

One of the first guide members 140 may be provided. However, in order for the first housing unit 100 to move more stably, it is preferable that at least two first guide members 140 are installed parallel to each other.

The first guide member 140 is fixedly coupled to one side of the first housing unit 100. In this embodiment, the first guide member 140 passes through the front end block 130, And the first guide member 140 is disposed so as to pass through one side of the second housing unit 200 (the second horizontal portion 211 to be described later in this embodiment).

The second housing unit 200 receives an external force in the direction opposite to the external force direction of the first housing unit 100. The second housing unit 200 is connected to the second housing unit 200 through external force providing means such as a load cell It is possible to receive an external force directly and receive a physical reaction force generated by an external force applied to the first housing unit 100 even if the external force is not directly supplied from the outside. Accordingly, the second housing unit 200 may be connected to the external force providing means or may be connected to a structure (fixing portion) fixed to the periphery.

In this case, the second housing unit 200 is provided with fixing means 240 for preventing the free flow of the package leads 10 placed on the front end block 130, And a shearing means 250 for covering the other layer except the layer sandwiched between the layers.

The fixing means 240 will be further described with reference to Figs. 4 and 5. Fig.

4 and 5 are views showing the structure of the lead fixture and the locking handle 242 according to the embodiment of the present invention. As shown further herein, the fixing means 240 mainly includes the lead fixture 241 A locking handle 242 may be included.

The lead fixing body 241 is freely movably installed on the first housing unit 100 toward the package lead 10 as shown in FIGS. 1 and 2 to prevent the package lead 10 from flowing freely .

Since the package lead 10 has no separate restraining means, it may be moved during the shear force test or may be bent forward, and the lead fixing body 241 enters the package lead 10 side, It is possible to prevent the package lead 10 from moving freely during the shear force test while preventing the package lead 10 from being pressed while maintaining the gap (about 0.02 to 0.05 mm), and in particular, to prevent the package lead 10 from being bent So that a stable shear force test can be carried out.

The locking handle 242 is also disposed in a direction crossing the lid fixture 241 so that when the lid fixture 241 needs to be fixed without moving in any one position, .

That is, the lead fixing body 241 must be fixed so as not to flow in a state maintaining a fine gap with the package lead 10 as described above. So that it does not flow at one position.

4 and 5 show a structure in which the locking handle 242 restricts and fixes the flow of the lead fixture 241. As shown here, the lead fixture 241 is provided with a part of the outer circumferential surface thereof, A trimming portion 241a is chamfered by a predetermined interval along the longitudinal direction of the base portion 241. [

In this embodiment, since the locking handle 242 is disposed at the lower portion of the lead fixing body 241, a trimming portion 241a is formed in a lower portion of the outer circumferential surface of the lead fixing body 241 except for both ends, The same structure.

The locking handle 242 is disposed at a lower portion of the lid fixing body 241. A portion of the locking handle 242 which contacts the trimming portion 241a is pressed against the lid fixing body 241 by rotation An eccentric portion 242a is formed.

Therefore, when the locking handle 242 is rotated in either direction, the eccentric portion 242a which is in contact with the trimming portion 241a is rotated to press the trimming portion 241a, (241) is pushed in one direction by the urging force and is brought into close contact with the inside of the second housing unit (200) to prevent the flow. Actually, the lead fixture 241 may not be greatly elevated as shown in FIG. 4, but this is exaggerated in order to facilitate explanation and understanding.

4, when the locking member 242 is rotated to the right to lock the lid fixing body 241, the lid fixing body 241 is slightly raised upward, (Not shown in detail) but is finely moved to the left (i.e., away from the package lead 10) in the drawing to maintain a fine gap (0.02 to 0.05 mm) with the package lead 10, 10 are not directly pressed by the lead fixing body 241. [

The shearing means 250 will be described with reference to FIGS. 6 to 8. FIG.

Fig. 6 is a plan view showing the configuration of the shearing means of this embodiment. Fig. 7 is a side view showing a state in which the shear shaft 251 of the present embodiment is engaged with the lead layer of the package lead. Fig. FIG. 3 is a view for schematically explaining a state in which a printed circuit board layer and a lead layer of a package lead are separated; FIG.

The shear means 250 may include a shear shaft 251, an adjusting screw 252 and an elastic member 253, which are connected to the package lead 10, (The lead 12 layer in the present embodiment) of the second housing unit 200, the transfer shaft 251 passes through the second housing unit 200, as shown in Fig. 7 And is allowed to enter the lead 12 layer of the package lead 10.

The adjustment screw 252 is for adjusting the amount of entry of the transfer shaft 251 into the package lead 10 (that is, the distance to the package lead 10) It is preferable to adjust the entry amount of the transfer shaft 251 through the adjusting screw 252 because the transfer arm 25 is freely movable toward the package lead 10.

The shear block 251 is moved toward the package lead 10 so that the shear load is limited only to the lead 12 layer. And the layer of the printed circuit board 11 of the lead 10 must be caught.

The lower end of the layer of the printed circuit board 11 is engaged with the front end block 130 and the front end shaft 251 is engaged with only the upper end of the layer of the lead 12, When the housing units 200 are relatively moved in opposite directions to each other, the printed circuit board 11 layer and the lead 12 layer of the package lead 10 are separated from each other, Shear force can be measured.

Therefore, it is very important to adjust the entry amount of the front end shaft 251 in the same manner as the amount of protrusion of the front end block 130, so that the adjustment screw 252 can finely adjust the entry amount of the front end shaft 251 Do it.

The adjusting screw 252 is installed between the coupling bar 254 and the second housing unit 200 formed in a direction intersecting the at least one turning shaft 251 and the adjusting screw 252 The distance between the coupling bar 254 and the second housing unit 200 is adjusted so that the entry amount of the rotation shaft 251 is adjusted.

Therefore, the elastic member 253 is provided to provide the elastic force in the direction in which the transfer shaft 251 is away from the package lead 10. [ The elastic member 253 is installed so as to surround the outer circumferential surface of the rotation shaft 251 between the coupling bar 254 and the second housing unit 200. However,

9, a separate shear bar 254 is coupled to a shear shaft according to an embodiment of the present invention. As shown in FIG. 9, at the end of the shear shaft 251, a package lead 10 A shear bar 254 for stably engaging the other layer (the lead 12 layer in the present embodiment) may be combined.

The transfer shaft 251 may be directly hooked to the lead 12 layer of the package lead 10 as described above. However, since the transfer shaft 251 is in the form of a rod, Can be relatively small.

Therefore, in order to stably catch the lead 12 layer of the package lead 10, or when the package lead 10 to be tested is relatively large, or when a very large shearing force is required, the rectangular bar- (254) is detachably coupled to the end of the transmission shaft (251).

The locking handle hole 242h may also be formed in the second housing body 210. [

The hole K for the shearing means is formed on the upper portion of the coupling member 220. The hole K for the shearing means is formed in the direction of the package lead 10 in the same manner as the hole for the lead fixture 241h, As shown in FIG.

In addition, the coupling piece 230 is configured to be stacked on the coupling member 220 as shown in FIG. 1, and can be coupled through a conventional coupling means (c).
