Description

Technical Field

[0001] The present invention relates to the technical field of semiconductor packaging equipment, and particularly relates to a multifunctional taping retest mechanism. Background Art

[0002] In the field of semiconductor manufacturing, the testing and quality control of chips are the core links to ensure product performance and reliability. Although chips need to undergo strict initial testing processes before packaging, there are still many potential risks that may cause chip performance degradation or latent damage during subsequent taping packaging, transportation, storage, or before delivery to customers. Thermal stress, mechanical stress, or environmental temperature and humidity changes during the packaging process may cause microcracks in the internal structure of the chip, loosening of bonding points, or degradation of the dielectric layer. Such defects may not be detected during initial testing but will gradually emerge during long-term use, directly affecting product reliability. In addition, vibrations, electrostatic discharges (ESD), or temperature and humidity fluctuations during taping transportation are likely to cause electrical parameter drift or physical damage, especially significantly affecting the signal integrity of high-frequency and high-precision chips. At the same time, terminal application scenarios such as automotive electronics and aerospace equipment have extremely strict requirements for chip failure rates (such as <1 DPPM), and double quality barriers need to be established through retesting to reduce the risk of downstream returns to the factory and meet the rigid requirements of full-life cycle quality traceability. Therefore, it is necessary to retest the tape.

[0003] Currently, the retest schemes commonly adopted in the prior art have significant limitations. Among them, traditional retest equipment is mostly designed for specific packaging forms (such as QFN, BGA) or single test items (such as DC parameters, functional tests). Poor compatibility leads to redundant production line equipment and rising costs. Semi-automatic equipment relies on manual intervention, with a long test cycle and low efficiency. At the same time, problems such as probe contact impedance and signal synchronization error are likely to cause misjudgment, making it difficult to meet the test accuracy requirements of high-density and high-speed signals such as 5G and AI chips. In addition, most systems lack the ability to dynamically analyze the correlation between test data and process parameters and cannot trace the root causes of defects, severely restricting the process of yield optimization and process improvement.

[0004] Therefore, the present application provides a multifunctional taping retest mechanism to solve the above technical problems. Summary of the Invention

[0057] As Figure 1-8 shown, an embodiment of the present invention provides a multifunctional taping re-inspection mechanism, including a sealing knife heat-sealing unit 4, a taping track unit 3, a first taping release and collection unit 1, a second taping release and collection unit 2, a vision detection and marking module, a data traceability module, and a multi-mode control unit.

[0058] The second tape mounting shaft 204 of the tape release and collection second unit 2 is used to store the tapes to be re-inspected. The tapes are guided by the second guide wheel 205 into the tape guide 302 of the tape track unit 3. The tape guide 302 achieves precise positioning through the driving of the driving ratchet 305 and the driven ratchet 306 by the ratchet driving motor 304. The sealing knife sealing integration 403 of the sealing knife heat-sealing unit 4 completes the heat-sealing or repair operation of the carrier tape and the cover tape. The first vision module 6, the second vision module 7, the third vision module 8, and the fourth vision module 9 of the vision inspection and marking module perform defect detection on the tape chips, and the marking module 5 marks the NG products. After the re-inspection is completed, the tapes are recycled through the first tape mounting shaft 106 of the tape release and collection first unit 1, or enter the NG rejection and re-tape process.

[0059] Among them, as Figure 2 shown, the tape release and collection first unit 1 includes a first vertical plate 101, a first mounting seat 102, a first tape mounting shaft 106, a first guide wheel 107, a first swing roller 108, and a first carrier tape tension alarm sensor 109. At the same time, in cooperation with Figure 3 shown, the tape release and collection second unit 2 includes a second vertical plate 201, a second mounting seat 202, a second tape mounting shaft 204, a second guide wheel 205, a second swing roller 206, a second carrier tape tension alarm sensor 207, and a cover tape collection guide wheel 208. The first swing roller 108 and the second swing roller 206 are installed on the vertical plate through bearings, and the swing angle range is ±15°, which can detect the carrier tape tension in real time. When the tension exceeds the threshold (such as 20N), the first carrier tape tension alarm sensor 109 or the second carrier tape tension alarm sensor 207 triggers a signal to control the emergency stop of the first motor 105 or the second motor 203. At the same time, the cutting knife control cylinder 104 drives the cutting knife unit 103 to cut the tape, and the protective cover 1010 prevents debris from splashing. The cover tape collection guide wheel 208 is driven by the third motor 209 to ensure the synchronization of the cover tape recycling and the tape transmission.

[0060] As Figure 4 shown, the tape track unit 3 is composed of a track support 301, a tape guide 302, a pressure wheel integration 303, a manual wheel 307, a floating plate adjustment part 3010, and a tension idler integration 309. The track support 301 is made of high-strength aluminum alloy, and the surface is treated by hard anodizing to improve wear resistance. The track width dynamic adjustment mechanism drives the movable side slide rail through the ratchet driving motor 304, so that the width of the tape guide 302 can be adjusted steplessly within the range of 8-50mm. The floating plate adjustment part 3010 controls the up and down floating (floating range ±2mm) of the sealing knife adjustable floating plate 308 through the spring force to ensure uniform contact with the guide rail during tape transmission. The polyurethane pressure wheel of the pressure wheel integration 303 adjusts the pressing force (10-30N) through air pressure to prevent the tape from shifting or slipping.

[0061] AsFigure 6 and Figure 7 As shown, the sealing knife heat-sealing unit 4 includes a taping sealing knife integrated vertical plate 401, a taping sealing knife integrated base 402, a sealing knife sealing integration 403, a sealing knife double-push cylinder 404, a cover tape cutting cylinder 405, a cover tape tightening integration 406, a first cover tape pressing cylinder 407, a second cover tape pressing cylinder 408, a cover tape release integration 409, a connecting block 4011, a sealing knife width adjustment part 4015 and a tape-retracting thrust cylinder 4012. The connecting block 4011 is fixed to the top of the taping sealing knife integrated vertical plate 401 and is used to rigidly fix the cover tape release integration 409 at the top position of the unit to ensure stable tension during the cover tape release process.

[0062] The sealing knife sealing integration 403 is made of high-temperature-resistant stainless steel (in this embodiment, it can specifically adopt but is not limited to high-temperature-resistant stainless steel of the SUS316L model), and internally integrates a ceramic heating sheet. The heat-sealing temperature is adjusted to 150 - 250 °C through a temperature control meter 2010 (the model of this temperature control meter 2010 can specifically adopt but is not limited to OMRON E5CN).

[0063] The sealing knife double-push cylinder 404 is driven by a cam 4013, and its stroke is monitored in real time by a sealing knife position sensor group (including a cover tape shortage alarm sensor 4010) to ensure that the heat-sealing position accuracy is ≤ 0.05 mm. The sealing knife width adjustment part 4015 adjusts the lateral displacement (±5 mm), vertical pressure (0 - 50 N) and heat-sealing angle (0 - 30°) of the sealing knife respectively through a first adjustment knob 4016, a second adjustment knob 4017 and a third adjustment knob 4018, so as to adapt to 8 packaging forms such as QFN and BGA.

[0064] At the same time, the cover tape cutting cylinder 405 and the tape-retracting thrust cylinder 4012 control the cover tape cutting and recycling through a linkage mechanism to ensure stable tension.

[0065] In addition, as shown in Figure 1 The visual inspection and marking module includes a marking module (5, a first visual module 6, a second visual module 7, a third visual module 8 and a fourth visual module 9. The first visual module 6 uses a 20-million-pixel CMOS sensor, equipped with a ring-shaped LED light source (wavelength 450 nm), to detect micro-cracks (resolution ≤ 5 μm); the second visual module 7 is equipped with a telecentric lens (focal length 50 mm) and a high-frequency flash unit to capture the looseness of bonding points (accuracy ±0.01 mm); the third visual module 8 integrates an infrared thermal imager (resolution 640×480) to analyze the abnormal temperature rise of dielectric layer degradation; the fourth visual module 9 uses a multi-spectral camera (visible light + near-infrared), combined with an AI algorithm (based on the ResNet-50 model) for comprehensive judgment, and the misjudgment rate is ≤ 0.05%. The marking module 5 can adopt a marker pen marking unit.

[0066] Meanwhile, for the data traceability and multi-mode collaborative control set in the present invention, its data traceability module is connected to the MES system through an industrial Internet of Things interface (supporting the Modbus TCP protocol), and test data (such as electrical parameters, defect types) and process parameters (such as heat sealing temperature, pressure) are uploaded in real time.

[0067] The multi-mode control unit is based on PLC programming and supports the following mode switches:

[0068] Cover tape repair mode: The stripping knife of the cover tape stripping part 3011 is driven by a cylinder to strip the damaged cover tape, and the sealing knife heat sealing unit 4 re-heats and cuts.

[0069] Re-testing and marking mode: The first vision module 6, the second vision module 7, the third vision module 8 and the fourth vision module 9 synchronously scan the tape, and the marking module 5 marks the NG products in real time.

[0070] NG rejection and re-encapsulation mode: The six-axis robot removes the NG chips according to the marked coordinates and re-packages the qualified products.

[0071] Standard encapsulation mode: The sealing knife heat sealing unit 4 and the tape track unit 3 operate in coordination, and the encapsulation speed is ≥ 200 chips / minute.

[0072] To sum up, in the present invention, the high-speed operation of the mechanism is jointly controlled by the drive motor 4014 of the sealing knife heat sealing unit 4 and the ratchet drive motor 304 of the tape track unit 3, and the test cycle is ≤ 3 seconds / chip. The tape guide 302 adopts a V-shaped groove design, and cooperates with the elastic pressing mechanism of the pressure wheel assembly 303 to ensure that the tape positioning accuracy under high-speed transmission is ≤ 0.1 mm.

[0073] The present invention covers any substitutions, modifications, equivalent methods and solutions made within the essence and scope of the present invention. For the public to have a thorough understanding of the present invention, specific details are described in detail in the following preferred embodiments of the present invention, and those skilled in the art can fully understand the present invention without these detailed descriptions. In addition, well-known methods, processes, procedures, components and circuits are not described in detail to avoid unnecessary confusion to the essence of the present invention.

[0074] The above are only the preferred embodiments of the present invention. It should be noted that for those of ordinary skill in the art, several improvements and refinements can be made without departing from the principle of the present invention, and these improvements and refinements should also be regarded as the protection scope of the present invention.
