Description

Technical Field

[0001] The present invention relates to the technical field of integrated circuit packaging, and in particular to an algorithm-based bonding machine false triggering prevention method and a semi-automatic bonding machine. Background Art

[0002] The bonding machine is a key device for integrated chip packaging, used to weld the leads between the substrate and the chip. The bonding operation process of the bonding machine is as follows: the substrate and the chip are positioned on the workbench, the bonding head moves to the top of the workbench, and then descends until the splitter touches the substrate or the chip. At this time, a corresponding trigger signal for bonding is generated, and the wire clamp assembly and the splitter assembly are controlled to work together to complete a wire bonding. If a false trigger occurs, the wire clamp assembly and the splitter assembly work together to complete an invalid wire bonding. Usually, the number of bondings is preset in the bonding machine before bonding. This invalid bonding affects subsequent bonding actions and may even cause the substrate and chip to be scrapped.

[0003] like Figure 1 and Figure 2 As shown, the bonding head assembly of the semi-automatic bonding machine is manually controlled by a rocker to drive the bonding head assembly to move in the horizontal and longitudinal directions. Exemplarily, the bonding head assembly has an upper contact and a lower contact. In the non-working state, the upper contact and the lower contact are in a contact state. When the splitting knife of the bonding head assembly is pressed against the substrate or the chip, the splitting knife is positioned together with the upper contact. Based on the downward movement trend of the bonding head assembly, the lower contact continues to move downward, and the upper contact and the lower contact are separated, generating a trigger signal. Based on the reset effect of the splitting knife assembly, when the splitting knife is released from the substrate or the chip, the upper contact and the lower contact resume the contact state. There are two situations of false triggering: if the operator improperly operates or misoperates the bonding head assembly from top to bottom, the splitting knife assembly provided with the upper contact is separated from the lower contact instantly when it conflicts with the substrate or the chip due to the inertia of the rocker moving downward, and an erroneous trigger signal is generated; when the work surface is knocked and vibrated, the splitting knife is triggered, and false triggering also occurs. False triggering will affect the smooth progress of the bonding process, thereby reducing production efficiency.

[0004] In order to solve the problem of false bonding triggering, the prior art uses some anti-false triggering control methods, which have achieved certain results. However, false triggering still occurs frequently, and it is impossible to completely avoid the occurrence of false triggering. For example, a longer time delay is set. After a 20ms delay after receiving the trigger signal, if the contacts are not closed (that is, the upper and lower contacts have not resumed the contact state), it is considered a normal trigger; if the contacts are closed within 20ms, it is considered a false trigger. The false triggering judgment method with this delay design is only applicable to workbench vibration. If an operator makes an error operation, the operator needs to react quickly within the delay window to lift the bonding head assembly to restore the upper and lower contacts to contact, which makes it difficult to avoid false triggering to a large extent. Summary of the invention

[0005] The purpose of the present invention is to propose an algorithm-based bonding machine false trigger prevention method and a semi-automatic bonding machine, which can obtain the acceleration mechanism to judge the false trigger, prevent the false trigger caused by the excessive movement speed of the bonding head assembly and the vibration of the workbench, and achieve the prevention of more than 95% of false triggers.

[0006] To achieve this object, the present invention adopts the following technical solutions:

[0007] A method for preventing false triggering of a bonding machine based on an algorithm, wherein the bonding machine comprises a frame, a workbench and a bonding head assembly arranged on the frame, wherein the bonding head assembly approaches and moves away from the workbench under the drive of a driving member, and the bonding head assembly is provided with an upper contact and a lower contact, and a trigger signal of a bonding response is generated when the bonding head assembly approaches the workbench and the upper contact is matched with the lower contact;

[0008] The method comprises the following steps:

[0009] Obtain the Z-axis displacement of the bond head, and calculate the real-time acceleration of the bond head assembly in the Z-axis by combining the time factor;

[0010] When a trigger signal for a bonding response is generated, the real-time acceleration at that moment is compared with a preset acceleration threshold. If the real-time acceleration is less than the acceleration threshold, it is determined to be a normal trigger, and the bonding head assembly completes a bonding response action according to the trigger signal;

[0011] If the real-time acceleration is greater than or equal to the acceleration threshold, it is determined to be a false trigger, and the bonding head assembly does not operate.

[0012] Furthermore, the moving distance of the bond head assembly is obtained by counting the pulses of the Z-axis grating ruler and the decoder, and the moving time of the bond head assembly is obtained by a timer;

[0013] By converting the moving distance and moving time into a difference operation based on the differential operation in the discrete system, the real-time speed and acceleration of the bonding head assembly in the Z axis can be obtained.

[0014] Furthermore, the period for calculating the real-time speed and the real-time acceleration is 50ms-200ms.

[0015] Furthermore, the acceleration threshold A is set according to the acceleration A1 of the bond head assembly under normal bonding, the acceleration A2 of the bond head assembly when it is reversing, and the acceleration A3 of the bond head assembly when the workbench vibrates. The setting conditions of the acceleration threshold are: A3≤A≤A1 and A<A2.

[0016] Further, according to the bond head assembly speed V1 under normal bonding, the bond head assembly speed V2 when the bond head assembly is reversing, and the bond head assembly speed V3 when the workbench is vibrating, a speed threshold range V of the bond head assembly is set, and the setting conditions of the speed threshold range are: V3<V≤V1 and V<V2;

[0017] When a trigger signal of a bonding response is generated, if the real-time acceleration is less than the acceleration threshold and the real-time speed is within the speed threshold range, it is determined to be a normal trigger.

[0018] Furthermore, the method further includes calculating a vector velocity of movement of the bond head assembly, and determining whether the bond head assembly changes direction within a preset time window according to the vector velocity;

[0019] If the bonding head assembly moves in a reverse direction within the time window, and the real-time acceleration is less than the acceleration threshold when a trigger signal for a bonding response is generated, it is determined to be a false trigger.

[0020] A semi-automatic bonding machine comprises a frame, a workbench and a bonding head assembly arranged on the frame, wherein the bonding head assembly is provided with a driving handle, an upper contact and a lower contact, and the bonding head assembly approaches and moves away from the workbench under the drive of the driving handle; when the bonding head assembly approaches the workbench until the upper contact and the lower contact cooperate, a trigger signal of a bonding response is generated;

[0021] The semi-automatic bonding machine also includes a control component, which is used to obtain the Z-axis displacement of the bond head movement and obtain the real-time acceleration of the bond head assembly on the Z-axis; the controller is also used to receive the trigger signal and compare the real-time acceleration with a preset acceleration threshold; if the real-time acceleration is less than the acceleration threshold, it is judged as a normal trigger, and the controller controls the bond head assembly to complete a bonding response action; if the real-time acceleration is greater than or equal to the acceleration threshold, it is judged as a false trigger, and the controller controls the bond head assembly not to act.

[0022] Furthermore, the control component includes a Z-axis grating ruler, a decoder and a controller, wherein the Z-axis grating ruler and the decoder are used to obtain the moving distance of the bond head assembly, and the controller is embedded with a timer for obtaining the moving time of the bond head assembly;

[0023] The controller is used to obtain the real-time speed and real-time acceleration of the bonding head assembly in the Z axis by converting the differential operation into the difference operation based on the discrete system through the moving distance and the moving time.

[0024] Furthermore, the controller is also used to calculate the vector velocity of the bond head assembly movement, and determine whether the bond head assembly changes direction within a preset time window according to the vector velocity;

[0025] If the bonding head assembly moves in a reverse direction within the time window, and the real-time acceleration is less than the acceleration threshold when a trigger signal for a bonding response is generated, it is determined to be a false trigger.

[0026] Furthermore, the acceleration threshold is 100 mm / s 2 -200mm / s 2 The controller calculates the real-time speed and the real-time acceleration in a period of 50ms-200ms.

[0027] The technical solution provided by the present invention may include the following beneficial effects:

[0028] 1. In the method of the present invention, by calculating the real-time acceleration of the bonding head assembly on the Z axis and the acceleration value comparison algorithm, it is determined whether the generated trigger signal is a false trigger, thereby suppressing the false trigger caused by inertia and workbench vibration, and preventing more than 95% of false triggers.

[0029] 2. The present invention further identifies false triggering within the switching time range of the bonding head assembly, further improves the avoidance of false triggering caused by workbench vibration, thereby further improving the reliability of false triggering prevention, and comprehensively avoiding false triggering due to inertia and workbench vibration.

[0036] Embodiments of the present invention are described in detail below, examples of which are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and cannot be understood as limiting the present invention.

[0037] The present invention provides an algorithm-based method for preventing false triggering of a bonding machine, which is applied to a bonding machine to achieve a reliable false triggering prevention effect. The bonding machine includes a frame, a workbench and a bonding head assembly arranged on the frame, the bonding head assembly approaches and moves away from the workbench under the drive of a driving member, the bonding head assembly is provided with an upper contact and a lower contact, and a trigger signal of a bonding response is generated when the bonding head assembly approaches the workbench and the upper contact cooperates with the lower contact.

[0038] Reference Figure 2 The algorithm-based bonding machine false triggering prevention method of the embodiment of the present invention comprises the following steps:

[0039] Obtain the Z-axis displacement of the bond head, and calculate the real-time acceleration of the bond head assembly in the Z-axis by combining the time factor;

[0040] When a trigger signal for a bonding response is generated, the real-time acceleration at that moment is compared with a preset acceleration threshold. If the real-time acceleration is less than the acceleration threshold, it is determined to be a normal trigger, and the bonding head assembly completes a bonding response action according to the trigger signal;

[0041] If the real-time acceleration is greater than or equal to the acceleration threshold, it is determined to be a false trigger, and the bonding head assembly does not operate.

[0042] In the method of the present invention, by calculating the real-time acceleration of the bond head assembly on the Z axis and the algorithm for comparing the acceleration values, it is determined whether the generated trigger signal is a false trigger, thereby suppressing the false trigger caused by inertia and workbench vibration, and preventing more than 95% of false triggers. Specifically, in the present invention, the real-time value of the acceleration of the bond head assembly is combined with the occurrence mechanism of the false trigger to determine the physical quantity characteristic threshold of the false trigger. When the bond head assembly changes from an ascending motion to a descending motion, its "acceleration" is the largest. The driven part (chopping knife assembly) of the bond head assembly will drive the upper contact to leave the lower contact located on the active structure due to inertia, resulting in contact separation. Therefore, after setting the acceleration threshold, the trigger above the acceleration threshold range is determined to be a false trigger. At this time, the bonding machine does not respond to the contact separation, which can avoid the occurrence of false bonding triggers.

[0043] In one embodiment of the present invention, the displacement of the bond head assembly is collected by using a Z-axis grating ruler and a decoder. Specifically, the moving distance of the bond head assembly is obtained by counting the pulses of the Z-axis grating ruler and the decoder, and the moving time of the bond head assembly is obtained by a timer.

[0044] By converting the moving distance and moving time into a difference operation based on the differential operation in the discrete system, the real-time speed and acceleration of the bonding head assembly in the Z axis can be obtained.

[0045] Specifically, the Z-axis grating ruler is fixed on the frame of the bonding machine, and the decoder is fixed on the bonding head assembly. When the bonding head assembly moves longitudinally, the pulse counts of the Z-axis grating ruler and the decoder obtain the longitudinal movement distance of the bonding head assembly. Exemplarily, the grating spacing of the grating ruler is set to x, and the relationship between the number of pulses n output by the decoder and the moving distance s is: s = x × n (mm). It can be understood that the smaller the grating spacing x of the grating ruler, the more accurate the calculated moving distance s.

[0046] Based on the displacement data, add the time t factor, perform differential operations, and obtain the real-time velocity value. In analog (continuous) systems: real-time velocity v = ds / dt. In discrete systems, differential operations are converted into difference operations: real-time velocity v = (s2-s1) / t, where t is the data sampling interval. Based on the velocity value, perform differential operations to obtain the real-time acceleration a value. In analog (continuous) systems: real-time acceleration a = dv / dt, in discrete systems, differential operations are converted into difference operations: real-time acceleration a = (v2-v1) / t, where t is the data sampling interval.

[0047] In order to further improve the reliability of preventing false triggering, in one embodiment of the present invention, referring to Figure 4 , the method also includes calculating the vector velocity of the movement of the bond head assembly, and judging whether the bond head assembly changes direction within a preset time window according to the vector velocity; if the bond head assembly changes direction within the time window, and the real-time acceleration is less than the acceleration threshold when the trigger signal of the bonding response is generated, it is judged as a false trigger. In this technical solution, false triggering within the reversing time range of the bond head assembly is further identified, and the avoidance of false triggering caused by the vibration of the workbench is improved, thereby further improving the reliability of false triggering prevention. Exemplarily, the decoder has two optical path signals, channel A and channel B. When the grating ruler and the decoder move relative to each other, the phases of the formed channel A pulse and channel B pulse differ by 90°. The phase of channel A leads, which means upward movement; the phase of channel B leads, which means downward movement. The current displacement direction can be obtained by the logical XOR operation of the two pulses, and the vector velocity of the movement of the bond head assembly can be calculated based on the time factor. Exemplarily, the time window is 5ms, which prevents false triggering caused by small vibrations of the workbench.

[0048] The present invention sets the acceleration threshold according to the motion data of the bond head assembly under normal bonding, the reversing motion data of the bond head assembly, and the motion data of the bond head assembly when the workbench vibrates. The data characteristics of the "speed" and "acceleration" of the bond head assembly obtained by experimental verification under various working conditions are preferably within the acceleration threshold range to ensure the accuracy of normal triggering and suppressing false triggering. The details are as follows.

[0049] The collection results of the bond head assembly motion data under normal bonding are shown in the following table.

[0050]

[0051]

[0052] In the table, v-max: the maximum velocity of the bond head assembly in one longitudinal movement; a-max: the maximum acceleration of the bond head assembly in one longitudinal movement; a-maxtime: the time when the maximum acceleration occurs; Flag-time: the contact separation time.

[0053] Under normal bonding conditions, workers of all skill levels performed the bonding operation relatively slowly, that is, the moving speed of the bond head assembly did not change much (15 mm / s-23 mm / s), and at the same time, the acceleration of the bond head assembly was not large (79 mm / s 2 -217mm / s 2 ), the time when the maximum acceleration occurs is basically the time when bonding is about to start or the time when bonding is completed (from motion to stop, or the direction of motion changes after bonding is completed).

[0054] The collection results of the bond head assembly commutation motion data are shown in the following table.

[0055]

[0056] The bond head reversing movement means that the bond head assembly moves up and then changes direction to move down. The moving speed range is 62mm / s-65mm / s, and the acceleration range is 898mm / s 2 -303mm / s 2 , and after the maximum acceleration is reached, the contacts separate. The most likely time for false triggering is during the reversing motion.

[0057] The collection results of the bond head assembly motion data when the worktable vibrates are shown in the following table.

[0058]

[0059]

[0060] The vibration intensity of the workbench is different, and the motion data of the bond head assembly caused by the collision with the wedge is also very different. The vibration of the workbench is generally caused by impact, which in most cases causes the bond head assembly to have a large speed and acceleration.

[0061] In the present invention, the acceleration threshold A is set according to the acceleration A1 of the bond head assembly under normal bonding, the acceleration A2 of the bond head assembly when the bond head assembly is reversing, and the acceleration A3 of the bond head assembly when the workbench vibrates. The setting conditions of the acceleration threshold are: A3≤A≤A1 and A<A2. Exemplarily, based on the motion data in the above three cases, the acceleration threshold is limited to 100mm / s 2 -150mm / s 2 , most of the false triggering can be eliminated.

[0062] The present invention further limits the speed threshold range V of the bond head assembly to fully avoid false triggering due to inertia and workbench vibration. The speed threshold range V of the bond head assembly is set according to the bond head assembly speed V1 under normal bonding, the bond head assembly speed V2 when the bond head assembly is reversing, and the bond head assembly speed V3 when the workbench vibrates. The setting conditions of the speed threshold range are: V3<V≤V1 and V<V2; refer to Figure 3 When a trigger signal of a bonding response is generated, if the real-time acceleration is less than the acceleration threshold and the real-time speed is within the speed threshold range, it is judged as a normal trigger. Exemplarily, based on the motion data in the above three cases, the speed threshold range V of the bonding head assembly is limited to 15mm / s-23mm / s.

[0063] It should be noted that, in the technical solution of the present invention, the period for calculating the real-time speed and the real-time acceleration is 50ms-200ms, preferably 50ms, to improve the reliability of false triggering situation judgment.

[0064] Correspondingly, the present invention also provides a semi-automatic bonding machine, comprising a frame, a workbench and a bonding head assembly arranged on the frame, wherein the bonding head assembly is provided with a driving handle, an upper contact and a lower contact, and the bonding head assembly approaches and moves away from the workbench under the drive of the driving handle; when the bonding head assembly approaches the workbench until the upper contact and the lower contact cooperate, a trigger signal of a bonding response is generated;

[0065] The semi-automatic bonding machine also includes a control component, which is used to obtain the Z-axis displacement of the bond head movement and obtain the real-time acceleration of the bond head assembly on the Z-axis; the controller is also used to receive the trigger signal and compare the real-time acceleration with a preset acceleration threshold; if the real-time acceleration is less than the acceleration threshold, it is judged as a normal trigger, and the controller controls the bond head assembly to complete a bonding response action; if the real-time acceleration is greater than or equal to the acceleration threshold, it is judged as a false trigger, and the controller controls the bond head assembly not to act.

[0066] In one embodiment of the present invention, the control assembly includes a Z-axis grating ruler, a decoder and a controller, the Z-axis grating ruler and the decoder are used to obtain the moving distance of the bond head assembly, and the controller is embedded with a timer for obtaining the moving time of the bond head assembly;

[0067] The controller is used to obtain the real-time speed and real-time acceleration of the bonding head assembly in the Z axis by converting the differential operation into the difference operation based on the discrete system through the moving distance and the moving time.

[0068] In one embodiment of the present invention, the controller is further used to calculate the vector velocity of the bond head assembly movement, and determine whether the bond head assembly changes direction within a preset time window according to the vector velocity;

[0069] If the bonding head assembly moves in a reverse direction within the time window, and the real-time acceleration is less than the acceleration threshold when a trigger signal for a bonding response is generated, it is determined to be a false trigger.

[0070] In one embodiment of the present invention, the controller pre-stores a speed threshold range of the bonding head assembly. When a trigger signal for a bonding response is generated, the controller determines that the real-time acceleration is less than the acceleration threshold and the real-time speed is within the speed threshold range, and then determines it as a normal trigger.

[0071] The semi-automatic bonding machine in the embodiment of the present invention realizes the prevention of false triggering based on the above method, achieving the prevention of false triggering of more than 95%, and the response speed of the prevention of false triggering is fast.
