Description

Hybrid test socket with mesh pins and blade pins of various sizes

[0001] The present invention relates to a hybrid test socket comprising mesh pins and blade pins of various sizes. Because it comprises mesh pins and blade pins of various sizes, it is suitable for high current and high frequency applications and allows for fine pitch adjustment.

[0002] Various electronic devices, such as display devices, use test sockets to inspect their electrical characteristics before shipping to ensure they have been manufactured properly. High-current blade pins and high-frequency blade pins are components included in test sockets used in devices that test circuits such as semiconductors or electronic devices. One end of the high-current blade pin and the high-frequency blade pin contact the lead terminal of the semiconductor under test, while the other end contacts the circuit of the testing device. This allows the input and output signals to be analyzed using the test circuit.

[0003] Recently, electronic devices have become increasingly miniaturized and feature a variety of functions, demanding high-current and high-frequency performance. Consequently, test sockets must be capable of measuring fine pitches and measuring high-current and high-frequency characteristics. However, conventional test sockets struggled to accommodate fine pitches, making measurement impossible or time-consuming and costly.

[0024]

[0025] FIG. 1 illustrates a hybrid test socket (100) according to an embodiment of the present invention, FIG. 2 is a view of FIG. 1 from below, and FIG. 3 is an exploded perspective view of FIG. 1.

[0026] Referring to FIGS. 1 to 3, a hybrid test socket (100) according to an embodiment of the present invention includes a mesh pin (111); a blade pin (112); a core (121, 122) including a first slit into which the mesh pin (111) is inserted and a second slit into which the blade pin (112) is inserted, and a body (130) into which the core (121, 122) is inserted and fixed.

[0027]

[0028] The above mesh-type pin (111) is a pin arranged in a mesh form on an elastic plate, so that even when fine pins are used, the spacing (pitch) between the pins is maintained constant. In the conventional case, it was difficult to manufacture very fine pins because the blade pins (112) had to be inserted into the slits of the core one by one, and since the pressure applied to each blade pin (112) was different, there was a problem that some of the blade pins (112) were deformed as the test was conducted, so that the spacing between the pins changed. The present invention forms a plurality of pins on a single elastic plate, so it is easy to manufacture a test socket, and it is possible to prevent poor contact from occurring due to the spacing between the pins changing during the test.

[0029] As described above, the mesh-type fin (111) may include an elastic plate and a plurality of fins arranged on the elastic plate.

[0030] The elastic plate may be capable of supporting a plurality of pins, absorbing pressure applied to the pins during testing, and having a certain elasticity to restore the original shape. For example, the elastic plate may be made of silicone.

[0031] The above pin is made of a conductive material, and various types of metals or alloys can be used. The shape of the pin is not particularly limited, and it can be manufactured to be much smaller and thinner than conventional blade pins.

[0032] Hereinafter, a method for manufacturing the mesh-type fin (111) will be described. First, a mesh pattern is formed on an elastic plate using conductive ink or the like. The elastic plate may be a silicon plate with a thickness of several tens of micrometers to several millimeters. The conductive ink contains copper, aluminum, or the like and can be hardened through heat treatment. Next, the elastic plate is cut into a predetermined size to manufacture the mesh-type fin (111).

[0033]

[0034] The above blade pin (112) may be for measuring high current characteristics and / or high frequency characteristics. The above blade pin (112) may have a shape and size suitable for measuring high current and / or high frequency characteristics.

[0035] In one embodiment, the blade pin (112) may have a shape that provides a certain degree of elasticity to cope with high currents. Furthermore, the blade pin (112) may have a zigzag shape or a spring-like shape to impart elasticity to cope with high frequencies. This may reduce noise and enable more accurate measurements. Thus, the shape and length of the blade pin (112) may be applied in various ways.

[0036] The above blade fin (112) may be made of a metal or alloy plate several millimeters thick, and the thickness or material is not particularly limited. In one embodiment, the thickness may be 0.1 mm, the width may be 1.0 mm, the length may be 7.5 mm, and the blade fin may be made of beryllium copper.

[0037]

[0038] The lengths of the mesh-type fin (111) and the blade fin (112) may be different from each other, and the depths of the first slit and the second slit may be different from each other. Referring to Fig. 4, the length of the mesh-type fin (111) may be shorter than that of the blade fin (112).

[0039]

[0040] The cores (121, 122) may include a first slit and a second slit into which the mesh-type pin (111) and the blade pin (112) are inserted. The cores (121, 122) may be integral, but may be composed of a first core (121) including the first slit and a second core (122) including the second slit. In this case, the first core (121) and the second core (122) each include a first slit and a second slit therein, and the mesh-type pin (111) and the blade pin (112) are inserted and arranged in the first slit and the second slit, respectively. The first core (121) and the second core (122) are arranged inside the main body to ensure that the mesh-type pin (111) and the blade pin (112) are stably arranged.

[0041] The first slit and the second slit are slits that penetrate the first core (121) and the second core (122) in the vertical direction. The mesh-type pin (111) and the blade pin (112) are inserted into the first slit and the second slit, respectively, and when a test is performed using the hybrid test socket (100), the mesh-type pin (111) and the blade pin (112) can move up and down or contract and relax inside the first slit and the second slit.

[0042] The first slit and the second slit may be arranged in multiples along at least one column, and the number and arrangement intervals are not particularly limited. The first slit and the second slit may be applied in various widths, depths, etc. according to the length and shape of the blade pin (112) inserted therein.

[0043]

[0044] Referring to Fig. 5, the lengths of the first core (121) and the second core (122) are different, and accordingly, the depths of the first slit and the second slit are different. In another embodiment, when applying three or more different types of pins, three or more types of cores may be applied depending on the type of pin.

[0045]

[0046] In another embodiment of the present invention, a test socket applicable to a fine pitch can be provided by manufacturing different types of pins by integrating them into a pin block (221). FIG. 6 discloses a core (220) (FIG. 6(a)) comprising a plurality of cores including pin blocks (221) each having different pins (211, 212) built into them, a single core (220) (FIG. 6(b)) including a plurality of pin blocks (221) each having different pins (211, 212) built into them, and a core (220) (FIG. 6(c)) in which the core itself is manufactured as a pin block and has different pins (211, 212) built into it. In this embodiment, the pins (211, 212) are fixedly arranged within small slots formed in the pin block (221). The pins (211, 212) fixed to the pin block (221) may be of one type, but may be of different types as needed. The worker can insert the pin block (221) into the core (220) to manufacture a test socket, or can manufacture the core (220) itself as a pin block, which makes manufacturing easy and allows for accurate manufacturing of the pitch, which is the distance between the pins (211, 212). The pin block (221) may be made of a polymer resin such as urethane, PVC, or Ultem, and includes a plurality of holes penetrating the body. The pins (211, 212) are inserted into the holes, filled with a polymer resin, and fixed in place.

[0047] Referring to Fig. 7, a method for manufacturing a test socket of the present embodiment will be described in more detail. First, a pin block (221) is prepared and fixed to a support jig (10) (Fig. 7(a)). Next, a pin (211) is placed in a groove of a slot jig (20). Next, one end of the slot jig (20) is aligned with the slot of the pin block (221), and then the slot jig (20) is tilted so that the pin is inserted into the slot of the pin block (221) (Fig. 7(b)). The slot jig (20) includes a plurality of grooves arranged at positions corresponding to the slots of the pin block (221), and the pin (211) moves into the slot along the grooves, so that the work can be performed accurately and quickly. In addition, even when the test socket requires a very small pitch, the pitch can be accurately controlled and manufactured by finely manufacturing the gap between the slot of the pin block (221) and the groove of the slot jig (20). The above slot jig (20) may have a shape in which the spacing between the grooves is fixed, but if necessary, the spacing between the grooves can be adjusted to manufacture a pin block (221) having a desired pitch as needed. Next, a liquid polymer resin can be injected into the slot of the pin block (221) and hardened to fix the pin (211) (Fig. 7(c)). The polymer resin may be a thermosetting resin and is not particularly limited. Next, the pin block (221) is separated from the support jig (10) and coupled to the core (220) (Fig. 7(d), (e)).

[0048]

[0049] The main body (130) performs a function of performing a test by being coupled to an external measuring device of the hybrid type test socket (100) and stably fixing the core (121, 122) and pin (111, 112) inside. The main body (130) may have a structure in which a plurality of blocks are stacked. Referring to FIG. 3, the main body (130) may have a structure in which a first plate (131), a second plate (132), a floating plate (133), and a third plate (134) are sequentially inserted or stacked.

[0050] The first plate (131) may be positioned at the top of the main body (130) and may include a hollow space into which the first core (121) and the second core (122) are inserted. In addition, the first plate (131) may be positioned at the top of the second plate (132) and the floating plate (133) to fix the floating plate (133).

[0051] The second plate (132) performs the function of wrapping and fixing the floating plate (133) from the outside. The second plate (132) may be placed below the first plate (131) and may include a hollow space into which the floating plate (133) is inserted.

[0052] The floating plate (133) functions to secure the first core (121) and the second core (122) by wrapping them from the side. In addition, the floating plate (133) functions to protect the lowermost portions of the pins (111, 112) when the multi-test socket (100) comes into contact with an external connector. That is, when the contact with the connector is stopped, the lowermost portions of the pins (111, 112) can be formed to go into the inside of the hole formed in the lower portion of the floating plate (133) so as not to be visible from the outside. The floating plate (133) may include a hollow portion into which the first core (121) and the second core (122) are inserted, and may be inserted and placed within the hollow portion of the second plate (132). In addition, the lower surface thereof may be in contact with the upper surface of the third plate (134). The size of the above floating plate (133) may be smaller than the sizes of the third plate (134) and the second plate (132).

[0053] The third plate (134) has an upper surface that contacts the first core (121) and the second core (122) or the buffer member (140) to stably fix the first core (121) and the second core (122), and may include a fastening groove for coupling with the second plate (132), etc.

[0054] Each component of the above main body (130) may be composed of ULTEM, ceramic materials, etc., but is not limited thereto.

[0055]

[0056] One embodiment may further include a buffer member (140) disposed between the lower surfaces of the first core (121) and the second core (122) and the main body (130). The buffer member (140) protects the first core (121) and the second core (122) from impact and performs a function of adjusting the lowermost portions of the mesh-shaped fin (111) and the blade fin (112) to be ejected to the lower portion of the body by an appropriate length. The buffer member (140) may be divided into a first portion that contacts the lower surface of the first core (121) and a second portion that contacts the lower surface of the second core (122), and the heights of the upper surfaces of the first portion and the second portion may be different from each other. In one embodiment, the height difference between the upper surfaces of the first and second portions may be the same as the height difference between the mesh fins (111) and the blade fins (112). If necessary, the thicknesses of the first and second portions may be different from each other.
