Description

Technical Field

[0001] The utility model relates to the field of semiconductor packaging, in particular to a cleaning tool for a fire rod. Background Art

[0002] Wire bonding is a semiconductor process that uses thin metal wires and utilizes heat, pressure, and ultrasonic energy to tightly weld metal wires to pads to achieve electrical interconnection between chips and substrates and information exchange between chips.

[0003] The steps of the wire bonding process usually include: the tail of the thin metal wire is exposed under the blade of the wire bonding machine; the spark rod of the wire bonding machine discharges electricity to melt the tail of the wire into a metal ball; the splitting knife moves to the chip bonding area and presses the metal ball downward onto the chip bonding area; the splitting knife applies pressure, ultrasonic wave outputs energy, and stops ultrasonic wave output after the action time is completed; lifts the splitting knife to form a metal ball on the chip bonding area; the splitting knife moves with the thin metal wire from the chip bonding area to the lead frame bonding area; the splitting knife moves downward to press the thin metal wire onto the lead frame bonding area; the splitting knife applies pressure, ultrasonic wave outputs energy, and stops ultrasonic wave output after the action time is completed, thereby forming a lead connecting the chip and the lead frame.

[0004] The spark rod of the wire-making machine is prone to carbon accumulation and needs to be cleaned regularly to avoid affecting the normal operation of the spark rod. The current method of cleaning the spark rod in the industry is to manually remove the spark rod bracket that supports the spark rod, and then use a dust-free cloth and metal polish to manually clean the spark rod on the spark rod bracket. This method is inefficient and affects the overall work efficiency. In addition, when the spark rod bracket is installed after cleaning, the spark rod may be misaligned, and the metal ball that meets the requirements cannot be formed, which has the risk of bad burning of the ball. For details, please refer to Figure 1 , which is a schematic diagram of the positions of the fire rod 100, the splitter 110 and the thin metal wire 120. When the fire rod 100 is facing the thin metal wire 120 at the edge of the splitter 110, the end of the thin metal wire 120 can form a metal ball that meets the requirements, such as Figure 2 As shown in part (a); after the cleaning is completed, if the ignition rod 100 is offset when installing the ignition rod bracket, for example, too high or too low, such as Figure 1 The position shown by the dotted line will cause the metal ball at the end of the thin metal wire 120 to have an abnormal shape, such as Figure 2 As shown in part (b), the area indicated by the arrow has an irregular shape. This type of metal ball cannot meet the requirements and may even affect the reliability of wire bonding. Summary of the invention

[0030] The specific implementation of the fire rod cleaning fixture provided by the utility model is described in detail below with reference to the accompanying drawings.

[0031] Figure 3 Schematic diagram of a cleaning tool for a fire rod provided by an embodiment of the utility model. Figure 4 This is a schematic diagram of an exploded view of a cleaning tool for a fire rod provided by an embodiment of the utility model. Figure 5 This is a cross-sectional schematic diagram of the grinding head of the fire rod cleaning fixture provided by the embodiment of the utility model. Please refer to Figure 3 , Figure 4 and Figure 5 The fire rod cleaning tool comprises: a body 300, wherein a driving device (not shown in the drawings) is disposed in the body 300; a locking device 310; a grinding head 320, which has a first end 321 and a second end 322 which are arranged opposite to each other, wherein the first end 321 is connected to the body 300 through the locking device 310, and the second end 322 has a grinding hole 323, wherein the grinding hole 323 allows the fire rod 400 (shown in the drawings) to be ground. Figure 6 and Figure 7 ) is inserted, and the driving device can drive the grinding head 320 to rotate relative to the fire rod 400 so that the inner wall of the grinding hole 323 grinds the outer wall of the fire rod 400.

[0032] The fire rod cleaning jig provided by the embodiment of the utility model utilizes the driving device to drive the grinding head 320 to rotate, thereby causing the inner wall of the grinding hole 323 to grind the outer wall of the fire rod 400, thereby removing the attachments on the outer wall of the fire rod 400, such as carbon deposits, to achieve the purpose of cleaning the fire rod 400. The fire rod cleaning jig provided by the embodiment of the utility model can clean the fire rod 400 without removing the fire rod bracket 410 from the device, thereby avoiding the abnormality of the metal ball caused by the misalignment of the fire rod 400 installation, and improving the reliability of wire bonding.

[0033] The body 300 may be used as a hand-held portion, and a user may hold the body 300 when cleaning the fire rod 400 .

[0034] The main body 300 is provided with a driving device, and the driving device is used to drive the grinding head 320 to rotate. In some embodiments, the driving device includes but is not limited to an electric motor. In some embodiments, the main body 300 is provided with a speed regulating device, and the speed regulating device is used to adjust the rotation speed of the driving device, thereby adjusting the rotation speed of the grinding head 320 relative to the fire rod 400. Specifically, the speed regulating device is used to adjust the rotation speed of the motor, thereby adjusting the rotation speed of the grinding head 320 relative to the fire rod 400. For example, the speed regulating device can adjust the rotation speed of the motor by changing the power supply frequency of the motor power supply, changing the resistance of the motor, or changing the input voltage of the motor. In some embodiments, as Figure 3 to Figure 5 As shown, the speed regulating device includes a speed regulating button 340 arranged on the side wall of the body 300, and the speed regulating button 340 can be connected to the controller of the driving device, and the driving device can be controlled to change the speed through the speed regulating button 340. In some embodiments, the speed regulating device can also control the on and off of the power supply of the driving device. The fire rod cleaning fixture also includes: a power supply device (not shown in the figure), which is electrically connected to the driving device and is used to supply power to the driving device. In some embodiments, the power supply device uses a built-in power supply to supply power to the driving device, for example, the power supply device uses a battery arranged in the body to supply power to the driving device. In another embodiment, the power supply device uses an external power supply to supply power to the driving device, for example, the power supply device uses a plug connected to a live socket to supply power to the driving device.

[0035] In some embodiments, the fire rod cleaning jig is provided with a separate power switch, which is connected to the power supply device, and the power switch is used to control the on and off of the power supply device when supplying power.

[0036] In some embodiments, a rotating member 350 is provided at the end of the body 300, and the rotating member 350 is connected to the driving device, and the driving device drives the rotating member 350 to rotate, and the rotating member 350 drives the grinding head 320 to rotate, thereby realizing the synchronous rotation of the driving device and the grinding head 320. In some embodiments, the rotating member 350 can be a rod with blind holes at both ends, the blind hole at one end of the rotating member 350 is sleeved on the rotating shaft of the motor, and the locking rod 324 of the grinding head 320 is inserted into the blind hole at the other end of the rotating member 350, thereby realizing the synchronous rotation of the driving device and the grinding head 320.

[0037] The locking device 310 is used to fix the grinding head 320 relative to the body 300. Specifically, the locking device 310 is used to fix the grinding head 320 relative to the rotating member 350. In some embodiments, the locking device 310 includes a locking screw, which passes through the side wall of the rotating member 350 and abuts against the locking rod 324 to fix the grinding head 320 relative to the rotating member 350. The driving device drives the rotating member 350 to rotate, thereby driving the grinding head 320 to rotate relative to the ignition rod 400.

[0038] The first end 321 of the grinding head 320 is connected to the body 300 through the locking device 310. In some embodiments, Figure 3 and Figure 4 As shown, the first end 321 of the grinding head 320 has a locking rod 324, and the locking rod 324 is inserted into the rotating member 350 of the main body 300. The locking screw passes through the side wall of the rotating member 350 and abuts against the locking rod 324, thereby realizing the connection between the first end 321 of the grinding head 320 and the main body 300.

[0039] The second end 322 of the grinding head 320 has a grinding hole 323, which may be a blind hole that allows the fire rod 400 to be inserted. Figure 5 , Figure 6 and Figure 7 As shown, Figure 6 is a schematic diagram of a fire rod 400, Figure 7The present invention is a schematic diagram of a fire rod 400 after being inserted into the grinding head 320 of the fire rod cleaning fixture provided by an embodiment of the utility model, wherein the grinding hole 323 extends from the second end 322 of the grinding head 320 to the inside of the grinding head 320. When the fire rod 400 needs to be cleaned, the user holds the main body 300, aligns the fire rod 400, and pushes the main body 300 to insert the fire rod 400 from the second end 322 of the grinding head 320 into the grinding hole 323. The driving device drives the grinding head 320 to rotate, and the fire rod 400 remains stationary, so that the inner wall of the grinding hole 323 grinds the outer wall of the fire rod 400 to remove attachments on the outer wall of the fire rod 400, such as carbon deposits, to achieve the purpose of cleaning the fire rod 400.

[0040] In some embodiments, the inner diameter of the grinding hole 323 is larger than the outer diameter of the fire rod 400. If there is attachment on the outer wall of the fire rod 400, the outer diameter will be increased. By setting the inner diameter of the grinding hole 323 larger than the outer diameter of the fire rod 400, the uncleaned fire rod 400 can be inserted into the grinding hole 323, and by pushing the grinding head toward the fire rod support, the thickness of the attachment on the surface of the fire rod 400 is gradually reduced as the fire rod is inserted, and the attachment on the surface of the fire rod 400 is further removed by rotating the grinding hole 323.

[0041] In some embodiments, Figure 6 As shown, the fire rod 400 includes a connecting portion 401 and an ignition head 402. One end of the connecting portion 401 is connected to the ignition head 402, and the other end is fixed to the fire rod bracket 410. The outer diameter D10 of the ignition head 402 is smaller than the outer diameter D11 of the connecting portion 401. The ignition rod bracket 410 is used to fix the fire rod 400. The connecting portion 401 and the ignition head 402 can be the same metal rod. Different regions of the metal rod have different outer diameters, thereby forming the connecting portion 401 and the ignition head 402.

[0042] In some embodiments, Figure 5 and Figure 7 As shown, the grinding hole 323 includes a first hole segment 325 and a second hole segment 326. The inner diameter D50 of the first hole segment 325 is smaller than the inner diameter (e.g., inner diameter D52) of the second hole segment 326. The first hole segment 325 is used to accommodate the ignition head 402, and the second hole segment 326 is used to accommodate the connecting portion 401. The grinding hole 323 is designed with the first hole segment 325 and the second hole segment 326 according to the shape of the ignition rod 400, so that the grinding hole 323 can adapt to the ignition rod 400.

[0043] In some embodiments, the inner diameter D50 of the first hole section 325 is larger than the outer diameter D10 of the ignition head 402, so that the uncleaned ignition head 402 can be inserted into the first hole section 325. Further, the difference between the inner diameter D50 of the first hole section 325 and the outer diameter D10 of the ignition head 402 is 0.05-0.15 mm, which, on the one hand, enables the uncleaned ignition head 402 to be inserted into the grinding hole 323, and on the other hand, ensures that most or all of the attachments on the surface of the ignition head 402 can be removed.

[0044] In some embodiments, the inner diameter of the second hole section 326 is larger than the outer diameter D11 of the connecting portion 401, so that the uncleaned fire rod 400 can be inserted into the second hole section 326. In some embodiments, the second hole section 326 is funnel-shaped, and the inner diameter of the second hole section 326 at the end surface of the second end 322 of the grinding head 320 is the largest, and the inner diameter of the second hole section 326 at the connection between the second hole section 326 and the first hole section 325 is the smallest, so that the fire rod 400 can be inserted into the grinding hole 323 by providing a larger opening. In addition, when the thickness of the attachments on the outer wall of the uncleaned fire rod 400 is relatively thick, the fire rod 400 cannot be fully inserted into the grinding hole 323 due to the limitation of the size of the grinding hole 323. In this case, in the initial stage of cleaning, the fire rod 400 can be accommodated by the larger inner diameter at the end of the second hole section 326. As the cleaning proceeds, the attachments on the surface of the fire rod 400 are gradually thinned, and the fire rod 400 can be gradually inserted into the grinding hole 323 to further clean the attachments. In some embodiments, the difference between the inner diameter D51 of the second hole section 326 at the end face of the second end 322 of the grinding head 320 and the outer diameter D11 of the connecting portion 401 is 0.1 to 0.3 mm. On the one hand, the uncleaned fire rod 400 can be inserted into the grinding hole 323, and on the other hand, it can ensure that most or all of the attachments on the surface of the fire rod 400 can be removed. In some embodiments, at the connection between the second hole segment 326 and the first hole segment 325 , the inner diameter D52 of the second hole segment 326 is greater than or equal to the inner diameter D50 of the first hole segment 325 .

[0045] In some embodiments, the inner diameter D50 of the first hole segment 325 is smaller than the outer diameter D11 of the connecting portion 401. Then, when the ignition head 402 is inserted into the grinding hole 323, the connecting portion 401 cannot be inserted into the first hole segment 325, thereby controlling the insertion depth of the ignition rod 400 into the grinding hole 323 and protecting the end of the ignition head 402 from being damaged by the end of the ignition head 402 touching the bottom of the grinding hole 323 due to the insertion being too deep. Further, in some embodiments, at the connection between the second hole segment 326 and the first hole segment 325, the inner diameter D52 of the second hole segment 326 is larger than the inner diameter D50 of the first hole segment 325. Then, the outer edge of the connecting portion 401 can be supported by the end surface of the first hole segment 325, thereby further controlling the insertion depth of the ignition rod 400 into the grinding hole 323.

[0046] In some embodiments, the fire rod 400 is fixed on the fire rod bracket 410, and the depth H1 of the grinding hole 323 is less than the length L1 of the fire rod 400 protruding from the fire rod bracket 410, or the depth H2 of the second hole section 326 is less than the length L2 of the connecting portion 401 protruding from the fire rod bracket 410, so that there is a gap between the end of the grinding head 320 and the fire rod bracket 410, and when cleaning the fire rod 400, the end of the grinding head 320 does not contact the fire rod bracket 410, thereby avoiding damage to the fire rod bracket 410 or the grinding head 320 caused by the rotation of the grinding head 320. Wherein, the fire rod bracket 410 is fixed on the wire striking device, and the fire rod 400 can be cleaned without removing the fire rod bracket 410 from the device. In some embodiments, the difference between the length L1 of the fire rod 400 protruding from the fire rod bracket 410 and the depth H1 of the grinding hole 323 is 0.1 to 0.5 mm, or the difference between the length L2 of the fire rod 400 protruding from the fire rod bracket 410 and the depth H2 of the second hole section 326 is 0.1 to 0.5 mm, so as to improve the cleaning level of the fire rod 400 while avoiding damage to the fire rod bracket 410 or the grinding head 320 caused by the rotation of the grinding head 320.

[0047] The fire rod cleaning jig provided by the embodiment of the utility model can clean the fire rod 400 without removing the fire rod bracket 410 from the device, can avoid metal ball anomalies caused by misaligned installation of the fire rod 400, and improves the reliability of wire bonding.
