Description

[0001] The invention relates to a test contact comprising a contact tip and a contact body, a device for handling a test contact comprising a contact tip and a contact body and a method for handling a test contact comprising a contact tip and a contact body by means of a device for handling a test contact.

[0002] Test contacts are known in the prior art for connecting two or more electronic components, particularly for conducting electrical energy. For example, US 7 876 087 B2 discloses test contacts designed as wires that are pre-bent between two dies. US 7 876 087 B2 also discloses spring-loaded test contacts whose spring arrangements are intended to compensate for unevenness in the surfaces against which the test contacts are brought into contact. US 2008 / 0 265 927 A1 discloses ferromagnetic contact elements that can be aligned using a magnetic template to produce a probe card. The specialist article "The principles of creating a magnetic mounting system: the physics every conservator needs to know" by Gwen Spicer, published in the ICON Textile Group Forum, discloses the possibility of arranging artifacts on a mount, for example a plate, by utilizing the mount's magnetic attraction force.

[0003] Test contacts are usually permanently connected to a first component, and the second component is plugged onto a contact tip of the test contact that partially protrudes from the first component. In addition to the conductive connection, the test contacts can additionally or alternatively serve to mechanically stabilize two or more components. To ensure stabilization of the mechanical connection and / or to create two or more conductive connections to form a more complex circuit, it is also common to use two or more test contacts to connect two components. In order to correctly position the test contact on the first component, it is necessary to arrange it in the correct orientation on, on or in the first component. The underside or another part of the test contact is arranged on, on or in the first component, while the contact tip points away from the first component.Therefore, handling the test contact is technically easiest if the contact tip can be grasped approximately from above, in other words from the direction in which the contact tip points.

[0004] The problem here is that, due to its design, the test contact rests sideways under the influence of gravity. Particularly with very small structures, for example in microtechnology, gripping the test contact at the contact tip is not reliably feasible or involves considerable effort. Correct gripping is usually necessary by repeatedly re-gripping using two or more tools or by manual adjustments. However, this requires additional time and the complex use of multiple tools. The tools must be carefully coordinated to ensure damage-free handling.

[0005] There is therefore a great need for a test contact, a device for handling the test contact and a method for handling the test contact by means of the device, which overcome the problems known in the prior art and ensure a fast, safe and reliably correct gripping of the test contact for further handling, in particular for installation in an electronic component.

[0006] The test contact, the device, and the method are intended, in particular, to facilitate and accelerate the gripping of the test contact and to minimize the use of tools and labor. In particular, the correct gripping of the test contact is to be ensured.

[0007] This object is achieved in a surprisingly simple but effective manner by a test contact according to claim 1, a device for handling a test contact according to claim 6 and a method for handling a test contact by means of the device according to claim 13.

[0008] According to the invention, a test contact comprising a contact tip and a contact body is proposed, wherein the contact body has an upright direction. The test contact is characterized in that the test contact comprises a core made of a ferromagnetic material, wherein the core is arranged below a center of gravity of the test contact in the upright direction.

[0009] The basic idea of ​​the invention is that a test contact lying on its side will at least partially upright in a magnetic field due to the core made of ferromagnetic material located below the center of gravity, so that the contact tip lifts off the ground and can be gripped safely and reliably by a tool. The upright position occurs because the magnetic force attracts the core more strongly than the material surrounding the test contact. Upright position means that the test contact rests on the ground with one or more surfaces and is rotated under the influence of the magnetic attraction of the magnetic field such that its underside rests on the ground. Depending on the initial position and design of the test contact, the upright position can also involve tilting the test contact over one or more edges.In other words, the test contact functions like a tumbler, but not due to the attraction of gravity, but rather due to the attraction of a magnetic field. The ferromagnetic core shifts the "magnetic center of gravity" of the test contact downward, just as a heavier material shifts the center of gravity in a tumbler. Raising the contact tip distances the contact tip from the substrate, allowing the tool to grasp the contact from above while completely enclosing the contact tip, allowing easy, quick, reliable, and safe handling of the test contact.

[0010] The test contact comprises a contact tip and a contact body. The contact body is installed with its underside in sections, in particular with a lower section, and / or completely on and / or in the first electronic component. The contact body may also additionally serve as a connection point for an electrical circuit that is to be connected to a second electronic component. The installation is preferably carried out in a form-fitting manner, in particular by overmolding, and / or with a material bond, in particular by soldering. For this electrical and / or mechanical connection, the test contact has a contact tip, which is later connected to a second electronic component during use, preferably by a form-fitting plug connection.

[0011] The underside or lower region of the contact body is the side or region of the contact body that is opposite the contact tip. The underside is therefore "bottom," while the contact tip, or the region where the contact tip is indirectly arranged on the contact body, is thus "top." The lower region of the contact body does not necessarily have to be connected to the underside of the contact body, but can also be spaced from it, with the lower region being at least largely below the geometric center of gravity of the contact body.

[0012] The geometric design of the test contact is essentially arbitrary; preferably, the contact body is cylindrical or cuboid, in particular cube-shaped, and / or substantially cylindrical, cuboid, and / or cube-shaped. The tip is preferably conical or pyramid-shaped, or substantially conical or pyramid-shaped, with the base of the cone or pyramid being arranged on the contact body or on an element arranged between the contact body and the contact tip. Particularly preferably, the contact tip and contact body are formed as a single piece together with the contact core.

[0013] The erection direction runs from the underside and / or the lower region in the direction of the contact tip or to the region where the contact tip is arranged indirectly on the contact body, in other words from bottom to top.

[0014] The test contact has a core made of ferromagnetic material, to which a magnetic field can exert a strong force of attraction. It should be noted that, apart from the core, the test contact is made of an electrically conductive material and / or electrically conductive materials with a lower magnetic permeability. This means that the magnetic field attracts the test contact, with the exception of the core, with a weaker force of attraction than the core itself. Preferably, the test contact, with the exception of the core, is made of one or more diamagnetic materials and / or one or more paramagnetic materials. Particularly preferably, the test contact, apart from the core, is made of copper, aluminum, gold, silver, or a mixture and / or alloy thereof. Where exactly the core is arranged in the test contact is arbitrary, as long as it is arranged below the center of gravity of the test contact when viewed in the upright direction.Preferably, the core is arranged in the contact body.

[0015] By means of the test contact according to the invention, it is possible to enable the gripping of the test contact in a simple, safe and reliable manner with a single tool and in this way to enable cost-effective and rapid handling, in particular gripping, of the test contact.

[0016] The term "essentially" means that only a minor, in particular insignificant, change, alteration, and / or deviation from the corresponding conditions occurs. In particular, a "substantially cylindrical, cuboid, cube, cone, or pyramid-shaped object" is essentially cylindrical, cuboid, cube, cone, or pyramid-shaped, with insignificant changes, alterations, and / or deviations from the shape occurring, in particular recesses or protrusions in the surface or distortions or compressions in parts of the basic shape or the entire basic shape.

[0017] The term "one-piece" refers to the ability to be manufactured in a single production process, such as, in particular, but by no means exclusively, a single potting process, specifically the encapsulation of the core with the material from which the test contact, with the exception of the core, is made. In particular, the subsequent attachment of additional separate components is not necessary. Subsequent corrective work, such as filing, is not considered a separate manufacturing process.

[0018] The term “ferromagnetic” refers to a material with a permeability much greater than 1, especially greater than 40.

[0019] The term “paramagnetic” refers to a material with a permeability of approximately 1, but greater than 1, in particular greater than 1 and less than 1.1.

[0020] The term “diamagnetic” refers to a material with a permeability of less than or equal to 1, but greater than 0.

[0021] Advantageous further developments of the invention, which can be implemented individually or in combination, are presented in the subclaims.

[0022] It is conceivable for the core to be arranged opposite the contact tip, in particular on the bottom side, in the contact body. “Bottom side” means that the core forms the underside of the contact body or is arranged in a lower region of the contact body, but at a distance from the underside. The core is preferably arranged in the lower third and at a distance from the underside. More preferably, the core is enclosed on several sides by the material of the remaining contact body. Particularly preferably, the core is completely enclosed by the material of the remaining contact body. The material of the remaining contact body is the material from which the contact body is made, with the exception of the core. This enables reliable positioning of the contact body by means of the magnetic field, since the core is located well below the center of gravity of the test contact.Even more preferably, the contact region in the contact body is arranged above the core. The contact region is the region that, when the test contact is installed in a first component, is connected to the first component in such a way that an electrical current can flow from or to the first component via the test contact to or from the contact tip in this region. This arrangement prevents an electrical current conducted through the test contact from the first component to the second component from passing through the core. Therefore, the electrical properties of the core material, in particular its electrical conductivity, can be disregarded when designing the test contact.

[0023] The term “spaced from the bottom” refers to an arrangement in which at least one layer of the material of the remaining contact body is arranged below the core.

[0024] In a further development of the invention, it is conceivable for the contact body to comprise a support surface and for the core to be flat and parallel to the support surface. The support surface is arranged at the bottom of the contact body. Due to the flat and parallel design of the core, the attractive force of the magnetic field creates a lever effect which places the test contact on the support surface. The support surface ensures that the test contact stands securely and firmly on it when the magnetic field is activated. If the contact body has a cylindrical or cuboid shape, as described elsewhere, the support surface preferably corresponds to the lower end face of the cylinder or an end face of the cuboid. The support surface is preferably flat.

[0025] Furthermore, it is conceivable that the core is made of iron, nickel, or cobalt, contains an iron, nickel, and / or cobalt component, or is made of a ferromagnetic alloy, in particular a ferromagnetic iron, nickel, and / or cobalt alloy. These materials are ferromagnetic materials whose magnetic permeability is sufficiently high to ensure that the test contact is set up by the attractive forces of a magnet.

[0026] In a further embodiment of the invention, it is conceivable for the test contact to comprise an arm, at one end of which the contact body is arranged and at the other end the contact tip. The contact tip preferably points away from the arm at a 90° angle. The design of contact tips that project laterally from the component and upwards and downwards by 90° is common and widespread, particularly for chips. An example of such a design is the dual inline package. With this design, it is particularly important to ensure that the center of gravity is usually outside the contact body. Therefore, a test contact designed in this way will fall over under the influence of gravity. If the test contact has a ferromagnetic core according to the invention, this test contact can also be set up and further processed quickly and easily.The design with an arm is a possible, but by no means exclusive, indirect arrangement of the contact tip on the contact body described elsewhere.

[0027] It is assumed that the definitions and / or the embodiments of the above terms apply to all aspects described below in this description, unless otherwise stated.

[0028] According to the invention, a device for handling a previously described test contact is further proposed, wherein the device comprises a plate. The device is characterized in that a magnetic field device comprising at least one magnet is arranged on the plate in such a way that the magnetic field of the magnet emerges substantially perpendicularly from the plate, wherein one or more of the test contacts according to the invention are arranged on the plate.

[0029] As previously described, it has been recognized as advantageous for the test contact to be upright and thus positioned for handling, as subsequent further handling of the test contact is possible in a technically simple and reliable manner. For this purpose, one or more test contacts are arranged on the plate. The magnetic field device with the at least one magnet, which is arranged such that the magnetic field of the magnet emerges essentially perpendicularly from the plate, attracts the core of the test contact by means of the resulting magnetic field, whereby an attractive force acts on the core. Since, according to the invention, the core is located below the center of gravity of the test contact, the test contact is erected. This happens in a similar way to a tumbler, except that a magnetic force acts on the test contact instead of the gravitational force.Once the test contact is placed in the upright position, subsequent handling of the test contact is quick, easy, and uncomplicated. The plate can be designed as desired. However, it should be horizontal and flat. Preferably, the magnetic field device comprises at least 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13, 14, 15, 16, 17, 18, 19, 20, 25, 30, 35, 40, 45, 50, 60, 70, 80, 90, or 100 identically or differently configured magnets. Further preferably, the magnetic field device comprises a control device for activating and deactivating the magnet or magnets. In particular, the magnet is an electromagnet, and the control device closes a switch in an electrical conductor to or from the electromagnet to activate the electromagnet and opens the switch to deactivate the electromagnet.

[0030] In the present case, “emanating substantially perpendicularly from the plate” means in particular that the field directions of the magnetic field in the area of ​​the plate in which the test contact is to be placed deviate by no more than 15° from the perpendicular to the plate.

[0031] In a further development of the invention, it is conceivable for the magnet to be arranged below, inside, next to and / or above the plate. This has the advantage that the force acting on the test contact acts maximally in the intended direction. This ensures the desired effect, namely the straightening of the test contact. The shape, orientation and / or design of the magnet must be tailored to the respective arrangement. It is obvious that a magnet arranged above the plate must be arranged at a distance from the plate that at least allows handling. In particular, it is conceivable for a bar magnet to be arranged below, above, next to and / or centrally within the plate, with one pole arranged at the top and the other pole at the bottom. The magnetic field then exits the plate essentially perpendicularly, with a different region of the magnetic field exiting the plate depending on the arrangement.With a horseshoe magnet, it is particularly conceivable for one leg to be positioned above the plate, the other below, and the crossbar connecting the legs to be positioned next to it. The legs are aligned parallel to the plate. In this way, the homogeneous part of the horseshoe magnet's magnetic field emerges perpendicularly from the plate.

[0032] Furthermore, it is conceivable for the magnet to be an electromagnet or a permanent magnet. An electromagnet has the advantage that it can be activated or deactivated. This means that the magnet can only be activated after the test contact has been placed on the plate, allowing the test contact to be easily positioned in the correct position. Furthermore, the electromagnet can be deactivated after or during handling, so that the magnetic forces no longer act on the test contact as soon as it is handled. For example, if the test contact is grasped by a tool and lifted, a smaller force acts on the test contact and / or less force is required to grip the test contact. This prevents damage, in particular bending, to the test contact during handling.A permanent magnet or a permanently activated electromagnet has the advantage that the magnetic force acts permanently on a test contact placed on the plate, so that the test contact is held more securely on the plate and is less likely to be pushed off the plate by the influence of external forces.

[0033] In one embodiment of the invention, it is conceivable for the device to comprise at least one insert, wherein the insert is arranged on or in the upper side of the plate. The insert is the area in which the test contact can be placed. It is conceivable for the insert to be placed and / or laid on the plate together with the test contact. The insert serves as a container for transporting the test contact. For this purpose, the insert is preferably designed with a rim and / or a lid. Furthermore, the insert can be optimized for the placement of the test contact, while the plate is optimized for the transmission of the magnetic field. For example, the insert can be particularly easy to clean and / or antistatic for this purpose. The insert is preferably made of glass. Particularly preferably, the device comprises at least 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13, 14, 15, 16, 17, 18, 19, 20, 25, 30, 35, 40, 45, 50, 60, 70, 80, 90 or 100 inserts.In order to place the insert at the correct location in the plate, it is preferred if the plate has a corresponding recess so that the insert is arranged in the top side of the plate. The device particularly preferably comprises at least two inserts, the magnetic field device comprising at least one electromagnet corresponding to the number of inserts, at least one of the electromagnets being assigned to each insert, and the assigned electromagnet being arranged such that the magnetic field of the assigned electromagnet emerges essentially perpendicularly from the assigned insert. In this way, two or more test contacts according to the invention can be placed on the device and individually prepared for handling. This enables, in particular, continuous and / or simultaneous handling orPreparing for handling the test contacts, with the various procedures located at different points or in different steps. This speeds up handling.

[0034] The term “on the top side of the plate” means that the insert rests on top of the plate and is possibly connected to it by a form-fitting and / or material fit.

[0035] The term “in the top of the plate” means that the insert is partially or completely recessed into a corresponding recess.

[0036] In a further development of the invention, it is conceivable for the plate to be made of a paramagnetic material. If the magnetic permeability of the material from which the plate is made is too high, as is the case with a ferromagnetic material, for example, the magnetic field is bundled by the plate in a shielding manner and cannot act on the core of the test contact lying on the plate. If the material is diamagnetic, the magnetic field is displaced from the plate and cannot act on the core of the test contact, or only to a weakened extent. Paramagnetic materials have a sufficiently low, but not too low, magnetic permeability. Furthermore, they minimize losses when using electromagnets that are activated or deactivated during handling, since only minimal hysteresis losses occur in the plate.

[0037] According to the invention, a method for handling a test contact described elsewhere by means of a device described elsewhere is further proposed, the method comprising the following steps: a. Placing the test contact on the plate of the device; b. Raise the test contact by activating the magnet.

[0038] By erecting the test contact, handling is made easy using simple and fewer tools or by hand. This is due to the fact that the test contact has a predictable orientation in space, with the tip of the test contact being raised. If necessary, the tool only needs to be rotated about one axis to enable handling. The erection of the test contact is achieved by the ferromagnetic core located below the center of gravity, which is acted upon by the magnetic field of the activated magnet, as described elsewhere. It is conceivable that step a. is carried out several times. This means that several, in particular at least two, test contacts are placed on the plate of the device. Furthermore, it is conceivable that several, in particular at least two, test contacts are erected by activating the magnet in step b.It is also conceivable that several processes and / or process steps are carried out simultaneously or at different times.

[0039] In a further development, the method comprises a step c. after step b., namely gripping the test contact by means of a handling device. Particularly preferably, the gripper is rotatable about an axis, in particular about the Z-axis. This allows the test contact to be gripped in the correct orientation. It is conceivable to move the gripper by means of a Cartesian axis system with a Z-axis. For this purpose, a carriage with a gripper is moved by means of a linkage in the XY plane, wherein the gripper is movable on the carriage and / or together with the carriage in the Z-axis perpendicular to the XY plane. The XY plane is the plane arranged parallel to the plate. Alternatively, it is conceivable to arrange the gripper on a robot arm. The robot arm or the Cartesian axis system with a Z-axis can lift the test contact after it has gripped it and position it at any desired location.For example, the robot arm or the Cartesian axis system with Z-axis can place the test contact at a previously determined location of a first electronic component, insert it into it and / or fasten it there with it.

[0040] It is also conceivable that the magnet is deactivated after gripping, and the handling device moves along with the attached gripper. This means that the robot arm or the Cartesian axis system with a Z-axis transports the test contact to a different location. By deactivating the magnet, the magnetic forces no longer act on the test contact, so the gripping force of the gripper can be reduced. This means that overall, lower forces act on the test contact, and it can be protected.

[0041] Further details, features, and advantages of the invention will become apparent from the following description of the preferred embodiments in conjunction with the subclaims. The respective features can be implemented individually or in combination with one another. The invention is not limited to the embodiments. The embodiments are illustrated schematically in the figures. The same reference numerals in the individual figures denote identical or functionally identical elements, or elements that correspond to one another in terms of their function.

[0042] In detail: Fig. 1 shows a test contact according to the invention, which is arranged on a first embodiment of a device according to the invention; Fig. 2 shows six test contacts according to the invention arranged on a second embodiment of a device according to the invention; and Fig. 3A to Fig. 3D a plurality of test contacts according to the invention arranged on a third embodiment of a device according to the invention, wherein the method according to the invention is carried out.

[0043] Fig. 1 shows a test contact 10 according to the invention, which is arranged on a first embodiment of a device 20 according to the invention. The test contact 10 comprises a contact tip 11 and a contact body 12. The test contact 10 is connected to a first component (not shown) via the contact body 12, so that a second component (not shown) can later be plugged onto the contact tip 11. A vertical arm 17 is arranged on the upper side of the contact body 12, at the other end of which the contact tip 11 is formed. The test contact 10 has a center of gravity 15. Furthermore, the test contact 10 has an erection direction 13, wherein the erection direction runs from bottom to top. The contact tip 11 runs parallel to the erection direction 13. In addition, the test contact 10 comprises a core 14, which is made of a ferromagnetic material and is arranged below the center of gravity 15. In the Fig. In the embodiment shown in Figure 1, the core 14 is elongated and arranged parallel to a support surface 16 on which the test contact 10 stands. The test contact 10 is arranged on an insert 26 of the device 20. The insert 26 is placed on a plate 21 of the device 20. Below the plate 21 is a magnetic field device 22 comprising a magnet 23. In this embodiment, this is an electromagnetic magnet that can be activated or deactivated by means of a control device 25. In the Fig. 1, the magnet 23 is activated and therefore creates a magnetic field 24 that projects essentially perpendicularly through the plate 21 and the insert 26. The magnetic field 24 creates a force that acts on the core 14, thus positioning the test contact 10 on the mounting surface 16.

[0044] Fig. Figure 2 shows six test contacts 10 according to the invention, which are arranged on a second embodiment of a device 20 according to the invention. In principle, the second embodiment of the device 20 corresponds to the first in Fig. 1 shown embodiment of the device 20 according to the invention. However, this differs from the one shown in Fig. 1 in that it comprises six inserts 26 on which six test contacts 10 can be arranged. The inserts 26 are evenly distributed on a plate 21. Below the plate 21 there is a magnetic field device 22 comprising six magnets 23 which can be activated or deactivated by means of a control unit 25, wherein in the Fig. 2, only the front three magnets 23 are shown. Each insert 26 is assigned a magnet 23. The individual magnets 23 can be activated separately, allowing parallel processing of the test contacts 10.

[0045] Fig. Figure 3A shows a third embodiment of a device 20 according to the invention, wherein the device 20 comprises a plurality of inserts 26. A test contact 10 is arranged on each insert 26. Below a plate 21 there is a magnetic field device 22 comprising a controllable magnet 23, which is arranged in the Fig. 3A is deactivated. Step a., namely the placement of the test contact 10 on the plate 21 of the device 20, was carried out in Fig. 3A has already been carried out several times.

[0046] Fig. 3B shows the device 20 from the Fig. 3A, wherein the magnet 23 is activated, so that a magnetic field 24 is emitted by the magnet 23. The magnetic field 24 aligns the test contacts 10 20 on the inserts 26. This means that step b., namely aligning the test contacts 10 by activating the magnet 23, has been performed. Due to their upright position, the test contacts 10 can be easily grasped by a gripper 31 arranged on a Cartesian axis system 30. The Cartesian axis system 30 comprises a carriage on which the gripper 31 is arranged, which is moved by means of a linkage. The gripper 31 is rotatable about the Z-axis A and movable along this axis.

[0047] Fig. Figure 3C shows an enlarged section of the device 20, with the magnetic field device 22 activated. The magnet 23 therefore emits the magnetic field 24, so that the test contacts 10 are aligned on the inserts 26 in the plate 21.

[0048] Fig. Figure 3D shows an alternative embodiment, wherein the gripper 31 is arranged on a multi-axis robot arm 32. The gripper 31 is also rotatable about an axis A.
