Description

Technical Field

[0001] The invention belongs to the technical field of insulation testing devices and relates to an environmentally friendly insulation bonding gold wire insulation testing device. Background Art

[0002] Gold bonding wire is a gold alloy wire used as a connecting wire in integrated circuits, also known as ball welding gold wire or lead gold wire. Gold bonding wire is an important material in the microelectronics industry. It is usually used in semiconductor packaging to connect chips and lead frames, and plays the role of importing and exporting current between the chip and the outside world. The production process of traditional gold bonding wire usually includes metal purification, wire drawing, insulation coating, annealing and other steps. The production of environmentally friendly insulating gold bonding wire requires reducing the use of harmful substances, reducing energy consumption and pollution emissions while ensuring conductivity, bonding strength and insulation performance. Environmentally friendly insulating gold bonding wire can achieve clean production and efficient use of resources while meeting the high-performance requirements of microelectronic packaging, which is in line with the development trend of ESG (environment, society, governance) in the global semiconductor industry.

[0003] Gold bonding wire plays a vital role in the field of electronic packaging, and its insulation performance directly affects the reliability and safety of electronic products. Therefore, it is very necessary to conduct insulation testing on gold bonding wires, so after the gold bonding wires are produced, their insulation performance needs to be tested. The traditional testing method is to prepare several sections of gold bonding wires first, and then use a winding machine to wind the gold wires on a conductive metal rod. Generally, the number of winding turns is about 10, and the spacing between each turn is the same. One end of the metal rod is connected to the high-voltage electrode (+) of the high resistance meter, and the two ends of the gold wire are fixed with conductive silver glue to short-circuit, and then connected to the measuring electrode (-) of the high resistance meter. By measuring the resistance value between the metal rod and the gold wire, the integrity and insulation performance of the insulating coating are evaluated. However, the traditional insulation test method requires a more sophisticated winding machine, and after winding, the two ends of the gold wire need to be fixed with conductive silver glue and then connected to the circuit. The whole operation is not only more troublesome, resulting in slow test efficiency, but also requires multiple groups to be tested each time to ensure the accuracy of the entire test. The winding, fixing and disassembly of the gold wire are more troublesome, and the equipment investment cost is relatively high. Therefore, we proposed an environmentally friendly insulated bonding gold wire insulation test device to solve the above problems. Summary of the invention

DETAILED DESCRIPTION

[0040] The following describes the embodiments of the present invention by specific examples, and those skilled in the art can easily understand other advantages and effects of the present invention from the contents disclosed in this specification. The present invention can also be implemented or applied through other different specific embodiments, and the details in this specification can also be modified or changed in various ways based on different viewpoints and applications without departing from the spirit of the present invention. It should be noted that the illustrations provided in the following embodiments only illustrate the basic concept of the present invention in a schematic manner, and the following embodiments and features in the embodiments can be combined with each other without conflict.

[0041] Example 1

[0042] like Figure 1-Figure 8 As shown, the environmentally friendly insulated bonding gold wire insulation testing device comprises a workbench 1 and a high resistance meter 7. The high resistance meter 7 is fixedly connected to one side of the top of the workbench 1 and is used for insulation testing of the bonding gold wire.

[0043] The testing device also includes a positioning mechanism arranged on the top of the workbench 1, which is used to fix the two ends of the alloy wire, and the positioning mechanism is electrically connected to the negative pole of the megger 7 through the second conductive wire 13; the positioning mechanism includes two symmetrically arranged positioning seats 6, which are used to fix the two ends of the alloy wire respectively, and a positioning groove 61 is opened on one side of the positioning seat 6, and a conductive plate 16 is fixedly connected to the bottom wall of the positioning groove 61, and a conductive branch line 17 is electrically connected to the conductive plate 16, and the conductive branch lines 17 on the two positioning seats 6 are extended to the outside and are electrically connected to the second conductive wire 13 after being aggregated, and the two positioning seats 6 are provided with a clamping assembly used in conjunction with the corresponding conductive plate 16. First, place one end of the alloy wire into the positioning groove 61 on one of the positioning seats 6, and place one end of the alloy wire on the conductive plate 16, then press one end of the alloy wire on the conductive plate 16 through the clamping assembly, and fix the other end of the alloy wire on the conductive plate 16 in the other positioning seat 6 in the same way, so as to complete the fixation of the two ends of the alloy wire. Since the two conductive plates 16 are electrically connected to the second conductive wire 13 through the conductive branch line 17, a path can be formed for testing the resistance value of the alloy wire.

[0044] In one aspect of the present embodiment, the clamping assembly includes a clamping screw 18 threadedly connected to the top of the positioning seat 6, the bottom end of the clamping screw 18 extends into the positioning groove 61 and is rotatably connected to a pressure plate 19 located above the conductive plate 16, the top end of the clamping screw 18 extends upward and is fixedly connected to a first knob 21, the top four corners of the pressure plate 19 are fixedly connected to guide rods 20, and the top ends of the four guide rods 20 slide through the top of the positioning seat 6 and extend upward. First, one hand holds one end of the steel wire and puts it into the positioning groove 61 and is located on the conductive plate 16, then the other hand turns the first knob 21 to drive the clamping screw 18 to rotate, and at this time, the pressure plate 19 can be driven to move downward, thereby completing the fixed compression of one end of the steel wire, and the other end of the steel wire can be fixed using the same operation method.

[0045] The testing device also includes a winding mechanism arranged on the top of the workbench 1, which is used to wind the alloy wire, and the winding mechanism is electrically connected to the positive pole of the high resistance meter 7 through the first conductive wire 10; the winding mechanism includes two guide rails 4 symmetrically arranged on the top of the workbench 1, and the same sliding plate 2 is slidably connected to the two guide rails 4, and the first mounting block 8 and the second mounting block 11 are fixedly connected to the top two sides of the sliding plate 2 respectively, and the interior of the first mounting block 8 is fixedly connected to a metal conductive disk 9, and the metal conductive disk 9 is electrically connected to the positive pole of the high resistance meter 7 through the first conductive wire 10, and a gold wire winding rod 3 is rotatably connected in the metal conductive disk 9, and the other end of the gold wire winding rod 3 is rotatably connected to one side of the second mounting block 11. The gold wire can be wound by rotating the gold wire winding rod 3, and the gold wire winding rod 3 and the metal conductive disk 9 are both made of metal conductive materials, such as copper or steel. When power is turned on, current can flow from the first conductive wire 10 connected to the positive pole to the metal conductive disk 9, and conduct the current to the gold wire winding rod 3, so that the resistance value of the gold wire can be tested through the high resistance meter 7, and then the insulation test is completed.

[0046] In one aspect of the present embodiment, the winding mechanism further comprises an arch frame 5 fixedly connected to the top of the workbench 1, and one side of the sliding plate 2 passes through the bottom of the arch frame 5, a gear 14 is fixedly sleeved on one end of the gold wire winding rod 3 close to the second mounting block 11, a rack 22 meshing with the gear 14 is fixedly connected to the bottom of the arch frame 5, and a handle 33 is fixedly connected to one side of the sliding plate 2. The handle 33 can be used to facilitate the sliding plate 2 to be pulled back and forth, and the operation is convenient. When the sliding plate 2 slides back and forth, the meshing movement of the gear 14 and the rack 22 can be used to make the gold wire winding rod 3 rotate during the back and forth movement of the sliding plate 2, so as to achieve the effect of automatic winding; in addition, after the gold wire winding rod 3 rotates in the metal conductive disk 9, it is always in a fitted rotation state, so it will not affect the final conductive effect, and the first conductive wire 10 is also made of a flexible material, so it will not cause any obstruction to the back and forth movement of the entire sliding plate 2.

[0047] The present invention can be used in the field of insulation testing of environmentally friendly insulating gold bonding wires, and can also be applied to other fields of the present invention.

[0048] Example 2

[0049] This embodiment is a further improvement of the previous embodiment: Figure 1-Figure 10As shown, the test device also includes a traction mechanism arranged on the positioning mechanism, which is used to traction and guide the fixed strengthened alloy wire, and is used in conjunction with the winding mechanism to make the strengthened alloy wire evenly wound on the winding mechanism for insulation testing; the traction mechanism includes a support plate 15 fixedly connected to one side of the two positioning seats 6, and the top surface of the support plate 15 is kept level with the bottom wall surface of the positioning groove 61, and the two sides of the top of the support plate 15 are symmetrically connected to two first rotating shafts 23, and the outer walls of the two first rotating shafts 23 are fixedly sleeved with fixed guide wheels 24, and the top of the outer wall of the gold wire winding rod 3 is embedded with a rotating shaft 31, and the top of the rotating shaft 31 is fixedly connected to a limiting disk 32. As shown Figure 1 and Fig.10 As shown, first, the two ends of the strengthened alloy wire are respectively passed around the side of the two fixed guide wheels 24 that are away from each other and pressed and fixed with the corresponding positioning seat 6, or after the two ends of the strengthened alloy wire are pressed and fixed, they are then passed around the outer sides of the two fixed guide wheels 24 for traction and guidance, and then the middle section of the strengthened alloy wire is dragged and moved in the direction of the sliding plate 2 to be straightened, and hung on the rotating shaft 31. At this time, the strengthened alloy wire is pulled and pulled by the two fixed guide wheels 24 and the rotating shaft 31 to form an angle with equal lengths of the extension lines on both sides; after the strengthened alloy wire is pulled and fixed, the sliding plate 2 is pushed to move in the direction of the positioning seat 6 by the handle 33. At this time, the meshing movement of the gear 14 and the rack 22 makes the gold wire winding rod 3 move and rotate. Since the strengthened alloy wire is sleeved on the rotating shaft 31, the rotating shaft 31 will rotate with the gold wire winding rod 3. , so it will gradually and automatically wind the strong alloy wire around the gold wire winding rod 3. During the winding process, the limit plate 32 will prevent the strong alloy wire from slipping during the traction and pulling process, thereby ensuring that the strong alloy wire can be wound around the gold wire winding rod 3; since the two fixed guide wheels 24 are fixed in position, the initial position of the rotating shaft 31 is also fixed each time, so the angle formed by the strong alloy wire after each traction is fixed, so through the angle and the diameter of the gold wire winding rod 3, it is possible to measure the length of the strong alloy wire that the gold wire winding rod 3 can be wound around when it rotates one circle, and then the corresponding required diameter of the gear 14 is designed according to the length, that is, to ensure that the distance moved by the gear 14 to drive the gold wire winding rod 3 to move around in one rotation can just match the length of the gold wire wound around one circle, so that the entire device will not be stuck and can perform the winding work normally.

[0050] In one aspect of the present embodiment, the traction mechanism also includes two fixed blocks 25 symmetrically fixedly connected to both sides of the bottom of the support plate 15, and the same bidirectional screw 26 is rotatably connected between the two fixed blocks 25. The positive and negative threaded sections of the bidirectional screw 26 are threadedly sleeved with nut blocks 28 that are slidably connected to the bottom of the support plate 15. The tops of the two nut blocks 28 are rotatably connected to the second rotating shaft 29. The top of the support plate 15 is symmetrically provided with two strip holes 151. The tops of the two second rotating shafts 29 pass through the two strip holes 151 respectively and extend upward. The outer walls of the two second rotating shafts 29 are fixedly sleeved with tensioning guide wheels 30 that fit and move with the top of the support plate 15. One end of the bidirectional screw 26 rotates through one side of one of the fixed blocks 25 and is fixedly connected with a rotating handle 27. When the two ends of the gold wire are fixed with two positioning seats 6 respectively, since the position of the positioning seat 6 is fixed, the initial position of the gold wire winding rod 3 is also fixed. When the alloy wire is pulled by the fixed guide wheel 24 and hung on the rotating shaft 31, the alloy wire will be loose because the length of the alloy wire being pulled or positioned each time is inconsistent. At this time, it is necessary to rotate the handle 27 to drive the bidirectional screw 26 to rotate, and then drive the two nut blocks 28 to move closer to each other. At this time, the first rotating shaft 23 is driven to move in the strip hole 151, thereby driving the tensioning guide wheel 30 to move, so as to achieve the effect of tensioning and straightening the alloy wire, which is convenient for the winding of the gold wire winding rod 3; in addition, in order to facilitate the tensioning and pulling of the alloy wire, the tensioning guide wheel 30 can also be set to a state of passing through the strip hole 151, which can not only reduce the moving friction between the support plate 15, but also prevent the alloy wire from being stuck under the tensioning guide wheel 30, causing extrusion and wear on the alloy wire. This technical effect can be designed according to actual conditions, as long as the tensioning effect of the alloy wire can be achieved. The edges of the two positioning seats 6 that are close to each other are each provided with a clearance gap 62 connected to the corresponding positioning groove 61. When the tensioning guide wheel 30 is used to tension and pull the reinforced alloy wire, the recess 62 can be used to allow the reinforced alloy wire to reach a larger pulling angle, thereby enabling tension and pulling of a longer reinforced alloy wire.

[0051] Example 3

[0052] This embodiment is a further improvement of the previous embodiment: Figure 1-Figure 9As shown, a plurality of groups of turn control components are equidistantly arranged at the top of the arch frame 5, which are used to accurately control the number of turns of the alloy wire winding, so as to facilitate the test of the resistance value. Each group of turn control components includes a sliding slot 51 opened at the top of the arch frame 5, and a limit column 34 is slidably connected in the sliding slot 51. An adjusting screw 35 is rotatably connected to one side of the limit column 34. One end of the adjusting screw 35 away from the limit column 34 is threadedly penetrated through the inner wall of one side of the sliding slot 51 and is fixedly connected to a second knob 36. A stop column 12 used in conjunction with the limit column 34 is fixedly connected to the top of the sliding plate 2 close to the arch frame 5. When the number of turns of the alloy wire winding needs to be set, the corresponding second knob 36 can be rotated to drive the adjusting screw 35 to rotate, and then the corresponding limit column 34 can be pushed outward. The position of each limit column 34 corresponds exactly to the position of each turn, as shown in FIG. Figure 7 As shown, assuming that there are five limit posts 34, the one closest to the stop post 12 is set to be one rotation of the gold wire winding rod 3, the next one is set to be two rotations, and so on, the fifth one is set to be five rotations. However, since the strong alloy wire is in an angle when it is pulled and stretched, the two extended sides of the angle will be symmetrically and evenly wound when the gold wire winding rod 3 winds the strong alloy wire. Therefore, when the gold wire winding rod 3 rotates one circle, the strong alloy wire is actually wound twice. Therefore, when setting the number of turns, the number of turns wound is calculated as a multiple set by the limit post 34; when the limit post 34 is pushed out, the moving sliding plate 2 drives the gold wire winding rod 3 to move to complete the winding of the strong alloy wire, and the sliding plate 2 drives the stop post 12 to move synchronously at the same time. When the stop post 12 conflicts with the limit post 34, the sliding plate 2 cannot continue to move. At this time, the number of turns of the strong alloy wire can be accurately controlled.

[0053] In one aspect of this embodiment, a stop ring 37 is fixedly sleeved on one side of the adjusting screw rod 35 located outside the arch frame 5. By setting the stop ring 37, when the stop ring 37 contacts the arch frame 5, the extension distance of the stop column 34 can be controlled and limited, so as to avoid the stop column 34 from being moved out of the sliding slot 51, thereby facilitating adjustment.

[0054] However, as is well known to those skilled in the art, the working principle and wiring method of the megger 7 are commonplace, and are conventional means or common knowledge, and will not be elaborated here. Those skilled in the art may make any selections according to their needs or convenience.

[0055] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the present invention rather than to limit it. Although the present invention has been described in detail with reference to the preferred embodiments, those skilled in the art should understand that the technical solution of the present invention can be modified or replaced by equivalents without departing from the purpose and scope of the technical solution, which should be included in the scope of the claims of the present invention.
