The present invention also relates to pogo pins, electrical connection pins and insertionless input connectors usable for high integration and high frequency.

1 is a cross-sectional view showing a conventional general pogo pin 10.

As shown in FIG. 1, the pogo pin 10 includes a spring 16 that exerts an elastic force on the upper probe 12, the lower probe 14, the upper probe 12, and the lower probe 14, and the upper probe ( A cylindrical body 18 which receives the lower end of 12) and the upper end of the lower probe 14 and the spring 16.

The upper probe 12 and the lower probe 14 have one end thereof caught by the cylindrical body 18 to prevent the outside of the cylindrical body 18 from being separated and are elastically applied by the spring 16.

FIG. 2 is a cross-sectional view showing a plurality of pogo pins 10 accommodated in one insulating body 20, illustrating the semiconductor package inspection socket 30.

In FIG. 2, the socket for inspecting a semiconductor package 30 includes a plurality of pogo pins 10 and an insulating body 20 for receiving the plurality of pogo pins 10 at predetermined intervals.

The plurality of pogo pins 10 are accommodated in the insulating body 20 such that the upper probe 12 protrudes on the upper surface of the insulating body 20 and the lower probe 14 protrudes on the bottom surface of the insulating body 20. The plurality of pogo pins 10 are elastically supported by the springs 16 and are accommodated in the insulating body 20 at intervals equal to the intervals of the external terminals 4 of the semiconductor package 2 in contact with the upper probe 12. . The lower probes 14 are arranged at the same interval as the contact pads 8 of the test board 6 positioned under the semiconductor package inspection socket 30.

For the inspection of the semiconductor package 2, the test board 6 is positioned under the semiconductor package inspection socket 30, and the semiconductor package 2 is positioned above the semiconductor package inspection socket 30. When the semiconductor package 2 is pressed, the external terminals 4 of the semiconductor package 2 contact the upper probe 12 of the pogo pin 10, and the lower probe 14 contacts the contact pad of the test board 6. Contact with (8). The upper probe 12 and the lower probe 16 are elastically supported by the spring 16 inside the pogo pin 10 to the upper and lower portions of the insulating body 20, respectively, so that the pogo pin 10 is formed of the semiconductor package 2. And electrical connection between the test board and the test board (6).

However, as miniaturization, integration, and high performance of the semiconductor package are progressed, the size of the pogo pin for inspecting the semiconductor package must be reduced, and the size of the inspection socket using the pogo pin needs to be reduced. In particular, the outer diameter of the pogo pin 10 should be reduced as the interval between the external terminals 4 of the semiconductor package 2 is narrowed.

In addition, to realize high performance, the loss and distortion of the electrical signal should be minimized during the electrical signal transfer process between the semiconductor package and the test board. This requires a stable transmission path and a minimum impedance on the transmission path.

However, conventional pogo pins are difficult to meet these requirements. First, the path through the spring 14 is turned by the number of times the spring is wound, the path is long, the spring is relatively poor electrical properties, so there are many unwanted impedance components. Thus, the path through the spring 14 is not suitable as a path for the transmission of electrical signals.

Therefore, in the conventional pogo pin 10, the electric signal transmission path uses a path through the upper probe 12, the cylindrical body 18 and the lower probe 14. The path through the cylindrical body 18 however has other problems.

The upper probe 12 and the lower probe 14 should be free to move up and down inside the cylindrical body 18. Therefore, the outer diameter of the upper probe 12 and the lower probe 14 accommodated inside the cylindrical body 18 should be smaller than the inner diameter of the cylindrical body 18. In some cases, the electrical contact between the cylindrical body 18 and the upper probe 12 and the lower probe 14 may be significantly reduced, thereby increasing the contact resistance. In particular, this problem is exacerbated as the signal to be transmitted becomes faster.

Accordingly, it is an object of the present invention to provide an effective, efficient and clear method and apparatus for overcoming the above problems.

Unless otherwise specified, the description of the first structure 200 may be common to the description of the second structure 300. Therefore, the description of the second structure 300 may be omitted.

The first structure 200 includes a first body portion 210 and a first connection portion 220, and the second structure 300 includes a second body portion 310 and a second connection portion 320.

The first central connecting leg 221 extends after forming a step with respect to the first body portion in the longitudinal direction extending from the first body portion 210. The first central connecting leg 221 is bent at the first bending point 223 and the second bending point 224.

The second central connecting leg 321 extends after forming a step with respect to the second body portion in extending in the longitudinal direction from the second body portion 310. The second center connecting leg 321 is bent at the third bending point 323 and the fourth bending point 324.

By bending at the first bending point 223, the second bending point 224, the third bending point 323, and the fourth bending point 324, the first central connecting leg 221 and the second central connecting leg 321 has a step with respect to the first body portion 210 and the second body portion 220.

The first connector 220 and the second connector 320 slide in a state of being in surface contact with each other. The first side connecting leg 222 of the first connecting part 220 and the second side connecting leg 322 of the second connecting part 320 may be in a superimposed state and may be in surface contact with each other. In FIG. 4, the pair of first side connecting legs 222 is above the pair of second side connecting legs 322 and slides in this state.

On the contrary, the first central connecting leg 221 slides in a state located below the second central connecting leg 321. The order in which the first center connecting leg 221 and the second center connecting leg 321 are stacked by the above step is in the order of stacking the first side connecting leg 222 and the second side connecting leg 322. The opposite is true.

In another aspect, the first central connecting leg 221 is located between the pair of second side connecting legs 322, and the second central connecting leg 322 is the pair of first side connecting legs 222. ), And slide in this state.

The sliding surface on which the first side connecting leg 222 and the second side connecting leg 322 are in contact with each other and slides faces in the opposite direction. The sliding surface of the first side connecting leg 222 is oriented toward the bottom of the drawing in FIG. 5A, and the sliding surface of the second side connecting leg 322 is facing the top of the drawing in FIG. 5A.

The first side connecting leg 222 and the first central connecting leg 221 also have opposite directions to the sliding surface. While the sliding surface of the first side connecting leg 222 faces the lower direction of the drawing, the sliding surface of the first central connecting leg 221 faces the upper direction of the drawing. Further, the second side connecting leg 321 and the second central connecting leg 321 also have opposite directions to the sliding surface. While the sliding surface of the second side connecting leg 322 faces the upper direction of the drawing, the sliding surface of the second central connecting leg 321 faces the lower direction of the drawing.

The sliding surface of the first side connecting leg 222 and the sliding surface of the second side connecting leg 322 are in contact with each other, and the sliding surface of the first central connecting leg 221 and the second central connecting leg ( In a state where the sliding surface of the contact 321 is in contact, the first side connecting leg 222 and the second side connecting leg 321 slide with each other and the first central connecting leg 221 and the second central connecting leg 321 slide with each other.

As shown in the enlarged view A of FIG. 5A, the first center connecting leg 221 is bent with a step larger than the thickness of the first side connecting leg 222. Accordingly, the point a of the first central connecting leg 221 is lower than the lower surface of the first side connecting leg 222. Starting from this position, the first center connecting leg 221 is gradually raised. Accordingly, the first central connecting leg 221 has an angle b with respect to the horizontal line. The angle b may be larger before the first center connecting leg 221 and the second center connecting leg 321 are joined than after being joined to each other. Therefore, after the first central connecting leg 221 and the second central connecting leg 321 are coupled, the first central connecting leg 221 and the second central connecting leg 321 are pressurized with each other. As a result, the first side connecting leg 222 and the second side connecting leg 322 formed integrally make a state of pressing each other.

On the other hand, the angle b may be formed on both the first central connecting bridge 221 and the second central connecting bridge 321, alternatively the first central connecting bridge 221 or the second central connecting bridge 321. It can also be formed in either. Accordingly, the first central connecting leg 221 is pressing against the second central connecting leg 321, or the second central connecting leg 321 is pressing against the first central connecting leg 221. Alternatively, the first central connecting leg 221 presses against the second central connecting leg 321 and the second central connecting leg 321 presses against the first central connecting leg 221. It may be.

4, the first body 210 and the second body 310 will be described.

The first body portion 210 includes a first body 218, a first stopper 215, and a first hanging hook 216.

The first body 218 forms a skeleton of the first structure 200, and the first stopper 215 protrudes from the first body 218 to prevent the spring from escaping out of the first structure 200. . And the first hook 216 protrudes from the first body 218 and is used to allow the end of the spring to be positioned between the first stopper 215 and the first hook 216. When the spring 400 is coupled to the first body portion 210, the first stopper 215 and the first hook 216 pass through the first hook 216 while pressing the end of the spring 400. When the end of the spring 400 is released in this state, the end of the spring 400 is limited in position between the first stopper 215 and the first hook 216.

The slide type pogo pin has been described above. However, the structure of this sliding pogo pin can be equally applied to the electrical connecting pin. Electrical connection pins are connectors that ensure electrical connection between any point. These electrical connection pins may not have the springs, hooks and stoppers that were on the pogo pins.

6 is a view showing an example of an electrical connecting pin according to an embodiment of the present invention.

In the electrical connecting pin according to an embodiment of the present invention, the alternative structure has the same structure as the pogo pin shown in Figs. There is no spring, no hook and no stopper.

The first structure 500 includes a first body portion 510 and a first connection portion 520, and the second structure 600 includes a second body portion 610 and a second connection portion 620.

The first connecting portion 520 includes a first central connecting leg 521 and a first side connecting leg 522, and the second connecting portion 620 includes a second central connecting leg 621 and a second side connecting leg ( 622. The structures and functions of the first central connecting leg 521, the first side connecting leg 522, the second central connecting leg 621, and the second side connecting leg 622 are described above. Since the legs are the same, a detailed description thereof will be omitted.

In the above description, the slide-type pogo pin and the electrical connecting pin have been described with a structure having two side connecting legs in one central connecting leg. However, the number of bridges is not limited thereto. For example, a structure having two central connecting legs and three side connecting legs is possible, and a larger number of connecting legs may be integrally formed.

2. Slide type Pogo pin  And manufacturing method of electrical connecting pin

Structures 200 and 300 according to an embodiment of the present invention may be manufactured by processing one metal plate member. After punching and bending the metal plate member using a stamping process, heat treatment and plating may be performed to manufacture the first structure 200 and the second structure 300, respectively. Heat treatment or plating may be performed prior to punching and bending processing.

Specifically, the first structural member 200 and the second structural member 300 are obtained before punching out of the metal plate member. Accordingly, the outer parts of the body parts 210 and 310 and the connection parts 220 and 320 have the same shape, but are not bent in the first center connection leg 221 and the second center connection leg 321 because they are before being bent. Thereafter, at the bending points 223, 224, 323, and 324, a workpiece having the same shape as that of the bent first structure 200 and the second structure 300 is obtained. In this case, a continuous stamping method may be applied. The workpiece is heat treated and plated to obtain a first structure 200 and a second structure 300.

Then, the end of the spring 400 is pressed while passing through the hooks 216 and 316, and the ends of the spring 400 are positioned between the stoppers 215 and 315 and the hooks 216 and 316.

According to an embodiment of the present invention, the structures 200 and 300 constituting the sliding pogo pin and the electric connecting pin have an advantage of being manufactured from one plate member. The body parts 210 and 310 and the connecting parts 220 and 320 constituting the structure 200 and 300 are integrated and may be manufactured by processing one plate member.

According to the exemplary embodiment of the present invention, the first structure 200 and the second structure 300 may have a predetermined stretchability in the bending process, may increase elasticity and strength by heat treatment, and have a small electrical resistance. A beryllium copper alloy is thus preferred, particularly ASTMC17200, a beryllium copper 25 alloy, although other materials may be used that meet mechanical and electrical requirements.

Meanwhile, as the plating material, a material having low electrical resistance such as gold may be used, and heat treatment such as annealing, normalizing, quenching, tempering, or the like may be used.

The material of the spring is advantageous to use a very high elastic strength, tensile strength and fatigue strength, but the electrical resistance does not need to be low. The material of the spring is preferably spring steel or stainless steel, but other materials satisfying mechanical requirements may be used.

In the exemplary embodiment of the present invention, the first structure 200 and the second structure 300 are elastically supported by the spring 400 and move up and down relatively in accordance with a load given from the outside, respectively. Has

In addition, even when the position of the first connector 220 and the second connector 320 is free to move with each other, the loss and distortion of the electrical signal can be minimized through the stable path of the electrical signals in a state where the surface contact is maintained. And can be adopted for the use of highly integrated and high frequency circuits.

In addition, a practical example will be described in the conventional pogo pin. The cylindrical body 18 has a thickness of at least 0.05 mm. Furthermore, considering 0.015 mm as the necessary clearance between the cylindrical body 18 and the spring 16, when omitting the cylindrical body 18, the space of 0.13 mm is added to twice the 0.05 mm plus twice the 0.015 mm. You can do it.

In other words, if the conventional pogo pin employs a spring of 0.37mm outer diameter in the cylindrical body 18 of 0.5mm outer diameter, the minimum separation distance of the external terminal that can be applied should be 0.6mm or more. That is, if the conventional pogo pin is employed, it can be applied only to semiconductor packages and the like with a pitch between the external terminals of 0.6 mm or more.

However, if the cylindrical body 18 is omitted in accordance with the present invention, there is an effect that the application object is very wide with a pitch interval of 0.47 mm or more.

In addition, to manufacture a conventional pogo pin, the process of processing the cylindrical body 18 is very difficult and the cost of assembling other components therein is also very high. In contrast, the pogo pin of the present invention can omit the cylindrical body 18 and there is no need to assemble other components in the cylindrical body 18. Therefore, the cost saved in the production process is high and the overall production cost can be greatly reduced.
