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] A bonder is a key piece of equipment for integrated chip packaging, used to solder wires between substrates and chips. The bonding process is as follows: the substrate and chip are positioned on a workbench. The bond head moves to the top of the workbench and then descends until the splitter contacts the substrate or chip. At this point, a trigger signal is generated, controlling the wire clamp and splitter assemblies to work together to complete a wire bond. If a false trigger occurs, the wire clamp and splitter assemblies work together to complete an invalid wire bond. The bonder typically has a preset number of bonding attempts before bonding. This invalid bond affects subsequent bonding operations and may even render the substrate and chip useless.

[0003] like Figure 1 and Figure 2 As shown, the bond head assembly of a semi-automatic bonding machine is manually controlled by a rocker, which drives the bond head assembly to move horizontally and vertically. For example, the bond head assembly has upper and lower contacts. In the non-operating state, the upper and lower contacts are in contact. When the bond head assembly's splitting blade presses against a substrate or chip, the splitting blade and the upper contact are positioned. Due to the downward movement of the bond head assembly, the lower contact continues to move downward, separating the upper and lower contacts and generating a trigger signal. Due to the reset action of the splitting blade assembly, the upper and lower contacts return to contact after the splitting blade and the substrate or chip are no longer in contact. There are two possible scenarios for false triggering: If the operator improperly or mistakenly operates the bond head assembly from top to bottom, the splitting blade assembly, equipped with an upper contact, can momentarily separate from the lower contact due to the inertia of the rocker's downward movement upon contact with the substrate or chip, generating an erroneous trigger signal. False triggering can also occur when the splitting blade is struck or vibrated by the work surface. 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 existing technology 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, if a longer time delay is set, when the trigger signal is received and there is a delay of 20ms, if the contacts are not closed (that is, the upper contact and the lower contact have not restored the contact state), it is regarded as a normal trigger; if the contacts are closed within 20ms, it is regarded as a false trigger. The false trigger judgment method of this design delay is only applicable to the vibration of the workbench. If the operator makes an error in operation, the operator needs to react quickly within the delay window to lift the bond 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 uses an acceleration mechanism to determine false triggering, and can prevent false triggering caused by excessive movement of the bond head assembly and vibration of the workbench, achieving a false trigger prevention rate of more than 95%.

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

[0007] An algorithm-based method for preventing false triggering of a bonding machine. The bonding machine includes a frame, a workbench and a bond head assembly disposed on the frame. The bond head assembly is driven by a driving member to move toward and away from the workbench. The bond head assembly is provided with an upper contact and a lower contact. When the bond head assembly approaches the workbench and the upper contact engages with the lower contact, a trigger signal for a bonding response is generated.

[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 bond 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 bond 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 real-time acceleration of the bond head assembly in the Z axis are 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 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] Furthermore, a speed threshold range V of the bond head assembly is set according to a speed V1 of the bond head assembly under normal bonding, a speed V2 of the bond head assembly when the bond head assembly is reversing, and a speed V3 of the bond head assembly when the worktable vibrates. The setting conditions of the speed threshold range are: V3 < V ≤ V1 and V < V2;

[0017] When a trigger signal for 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 reverses movement within a preset time window based on the vector velocity;

[0019] If the bond head assembly reverses and moves 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 determined to be a false trigger.

[0020] A semi-automatic bonding machine comprises a frame, a workbench and a bonding head assembly mounted on the frame, wherein the bonding head assembly is provided with a driving handle, an upper contact and a lower contact. The bonding head assembly is driven by the driving handle to move toward and away from the workbench. When the bonding head assembly approaches the workbench until the upper contact engages with the lower contact, a trigger signal for 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 assembly 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 on the Z axis by converting the differential operation into a difference operation based on the movement distance and the movement time in the discrete system.

[0024] Furthermore, the controller is further configured to calculate a vector velocity of movement of the bond head assembly, and determine whether the bond head assembly has reversed its movement within a preset time window based on the vector velocity;

[0025] If the bond head assembly reverses and moves 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 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 can have the following beneficial effects:

[0028] 1. In the method of the present invention, by calculating the real-time acceleration of the bond 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 false triggers 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 reversing 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.

[0030] 3. By limiting the velocity threshold range V of the bond head assembly and comparing the acceleration and velocity values, false triggering caused by inertia and workbench vibration can be completely avoided. BRIEF DESCRIPTION OF THE DRAWINGS

[0036] The following describes embodiments of the present invention in detail. Examples of the embodiments 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 intended only to explain the present invention and are not to be construed as limiting the present invention.

[0037] The present invention provides an algorithm-based method for preventing false triggering of a bonding machine. The method is applied to a bonding machine to achieve reliable false triggering prevention. The bonding machine includes a frame, a workbench mounted on the frame, and a bond head assembly. The bond head assembly is driven by a driver to move toward and away from the workbench. The bond head assembly is provided with an upper contact and a lower contact. When the bond head assembly approaches the workbench and the upper contact engages with the lower contact, a trigger signal indicating a bonding response is generated.

[0038] Reference Figure 2 The algorithm-based bonding machine false triggering prevention method according to an embodiment of the present invention includes 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 bond 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 bond 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, the present invention uses the real-time value of the acceleration of the bond head assembly, 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 upward motion to a downward motion, its "acceleration" is the largest. Due to inertia, the driven part of the bond head assembly (the splitting knife assembly) will drive the upper contact to leave the lower contact located on the active structure, resulting in contact separation. Therefore, after setting the acceleration threshold, a trigger above the acceleration threshold range is determined to be a false trigger. At this time, the bonding machine does not respond to this contact separation, thereby avoiding the occurrence of false bonding triggers.

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

[0045] Specifically, the Z-axis scale is fixed to the bonding machine frame, and the decoder is fixed to the bond head assembly. When the bond head assembly moves longitudinally, the pulse counts of the Z-axis scale and the decoder obtain the longitudinal movement distance of the bond head assembly. For example, assuming the scale's grating pitch is x, the relationship between the number of decoder output pulses n and the movement distance s is: s = x × n (mm). It can be understood that the smaller the scale's grating pitch x, the more accurate the calculated movement distance s.

[0046] Based on the displacement data, the time factor t is added and a differential operation is performed to obtain the real-time velocity value. In analog (continuous) systems: real-time velocity v = ds / dt. In discrete systems, the differential operation is converted to a difference operation: real-time velocity v = (s2-s1) / t, where t is the data sampling interval. Based on the velocity value, a differential operation is performed to obtain the real-time acceleration a value. In analog (continuous) systems: real-time acceleration a = dv / dt. In discrete systems, the differential operation is converted to a difference operation: 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 bond head assembly movement, and judging whether the bond head assembly reverses and moves within a preset time window based on the vector velocity; if the bond head assembly reverses and moves within the time window, and the real-time acceleration is less than the acceleration threshold when the trigger signal of the bond response is generated, it is judged as a false trigger. This technical solution further identifies the false trigger within the reversal time range of the bond head assembly, improves the avoidance of false triggers caused by the vibration of the workbench, and thus further improves the reliability of preventing false triggers. Exemplarily, the decoder has two optical path signals, channel A and channel B. When the grating scale and the decoder move relative to each other, the phases of the channel A pulse and channel B pulse formed differ by 90°. If the phase of channel A is ahead, it means upward movement; if the phase of channel B is ahead, it 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 bond head assembly movement can be calculated based on the time factor. Exemplarily, the time window is 5ms, which prevents false triggers caused by small vibrations of the workbench.

[0048] The present invention sets the acceleration threshold based on the bond head assembly's motion data during normal bonding, bond head assembly reversal, and worktable vibration. Experimental verification of the bond head assembly's "velocity" and "acceleration" data characteristics under various operating conditions optimizes the acceleration threshold range to ensure accurate triggering and prevent 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 move relatively slowly during the bonding operation, that is, the movement speed of the bond head assembly does not change much (15mm / s-23mm / s). At the same time, the acceleration of the bond head assembly is also not large (79mm / s 2 -217mm / s 2 ), the moment 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 reversing motion data are shown in the following table.

[0055]

[0056] The bond head reversing movement is when the bond head assembly moves up and then moves 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 reversing motion.

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

[0058]

[0059]

[0060] The motion data of the bond head assembly generated by the collision with the wedge varies greatly depending on the intensity of the worktable vibration. Worktable vibration is generally caused by impact, which in most cases causes the bond head assembly to have large speeds and accelerations.

[0061] In the present invention, the acceleration threshold A is set based on 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. For example, based on the motion data in the above three cases, the acceleration threshold is limited to 100mm / s 2 -150mm / s 2 , you can eliminate most of the false triggering.

[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 speed V2 when the bond head assembly is reversing, and the 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 for 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, the trigger is determined to be normal. For example, based on the motion data in the three scenarios described above, the speed threshold range V of the bond head assembly is limited to 15 mm / s-23 mm / 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 further provides a semi-automatic bonding machine, comprising a frame, a workbench and a bonding head assembly provided 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 is driven by the driving handle to approach and move away from the workbench; when the bonding head assembly approaches the workbench until the upper contact and the lower contact engage, a trigger signal for 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, 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;

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

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

[0069] If the bond head assembly reverses and moves 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 determined to be a false trigger.

[0070] In one embodiment of the present invention, the controller pre-stores a speed threshold range of the bond 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 by more than 95%, and the response speed of the prevention of false triggering is fast.
