Description

Technical Field

[0001] This invention relates to the field of frequency correction technology for electronic devices, and more particularly to a local frequency correction device and method. Background Technology

[0002] In the electronic component manufacturing process, frequency correction plays a crucial role in ensuring product performance. Currently, most frequency correction machines are primarily designed for wafer correction, making it difficult to achieve precision for individual, small surface-mount devices like those handled by the company. This affects the aesthetics of the socket casing and, more seriously, introduces numerous hidden dangers into subsequent sealing processes, leading to frequent defects such as cold solder joints and incomplete soldering, significantly reducing the product yield and increasing production costs. Moreover, existing technologies lack effective solutions for other products requiring partial frequency correction. Summary of the Invention

[0003] The technical problem to be solved by the present invention is to provide a local frequency correction device and method to address the shortcomings of the prior art.

[0004] The technical solution of the present invention to solve the above-mentioned technical problems is as follows: a local frequency repair device, comprising: a frequency repair machine, a baffle for opening and closing the electron beam of the frequency repair machine, and a template for blocking the non-frequency repair area in the product to be repaired, wherein the baffle is movably installed at the output end of the frequency repair machine, and the template is adapted to the product to be repaired.

[0005] The beneficial effects of adopting the technical solution of this invention are as follows: By designing a baffle for controlling the electron beam switch for frequency repair and a flexibly replaceable template adapted to the product to be repaired, the electron beam's effective area can be precisely controlled through the cooperation of the template and the baffle, effectively avoiding damage to non-repaired areas of the product, improving the accuracy of frequency repair, and ensuring product quality. It solves the problem of easily damaged peripheral parts during the frequency repair process for various products requiring localized frequency repair, improving the accuracy and applicability of frequency repair.

[0006] Furthermore, the product to be repaired is a square surface-mount device with a side length of 3mm. The product to be repaired has a square chip with a side length of 1.5mm. The template is a square template with a square opening with a side length of 1.5mm in the center, so that the template can be adapted to the product to be repaired.

[0007] The beneficial effects of adopting the above-mentioned further technical solution are as follows: For micro-surface-mount devices with a size of 3×3mm that require frequency repair of 1.5mm×1.5mm chips, a square template with a 1.5mm×1.5mm opening in the center can be selected. This facilitates the selection of a suitable template based on the shape and size of the repair area of ​​the product to be repaired, and makes it easier for the template to be adapted to the product to be repaired.

[0008] Furthermore, the template is square, circular, triangular, rectangular, trapezoidal, or rhomboid in shape; the center of the template is provided with a square opening, circular opening, triangular opening, rectangular opening, trapezoidal opening, or rhomboid opening; the frequency repair machine is provided with a workbench for placing the product to be repaired and a clamp for fixing the product to be repaired.

[0009] The beneficial effects of adopting the above-mentioned further technical solution are: the template shape is not limited and can be any shape such as square, circle, or triangle, and the size can also be adjusted according to actual product requirements. It facilitates the selection of a suitable template based on the shape and size of the repair area of ​​the product to be repaired. It also facilitates template compatibility with the product to be repaired. If the product is different and a circular area needs repair, a template with a corresponding circular opening in the center can be used instead.

[0010] Furthermore, the shape and size of the template are adapted to the product to be repaired, the product to be repaired has a chip to be repaired, and the center of the template has an opening, the shape and size of which are adapted to the chip to be repaired.

[0011] The beneficial effects of adopting the above-mentioned further technical solution are: frequency correction is only performed on the specific area of ​​the product that needs frequency correction when the electron beam passes through the opening of the corresponding shape and size on the template. This allows the electron beam to be precisely confined within the target frequency correction area of ​​the product, effectively avoiding unnecessary damage to surrounding parts, providing strong support for the smooth progress of subsequent processes, and significantly improving the frequency correction quality and production efficiency of various products.

[0012] Furthermore, the baffle is slidably installed at the output end of the frequency repair machine, or the baffle is rotatably installed at the output end of the frequency repair machine.

[0013] The beneficial effects of adopting the above-mentioned further technical solution are: the baffle is slidably or rotatably installed at the output end of the frequency repair machine, which facilitates the baffle to partially block, completely fold, or completely unblock the electron beam emitted by the output end of the frequency repair machine, thereby realizing the opening and closing of the electron beam of the frequency repair machine. This improves the applicability of the local frequency repair device.

[0014] Furthermore, when the baffle is slidably installed at the output end of the frequency repair machine, the output end of the frequency repair machine is equipped with a first driving mechanism for driving the baffle to slide, the first driving mechanism is connected to the baffle, and the first driving mechanism is connected to a controller; when the baffle is rotatably installed at the output end of the frequency repair machine, the output end of the frequency repair machine is equipped with a second driving mechanism for driving the baffle to rotate, the second driving mechanism is connected to the baffle, and the second control mechanism is connected to a controller.

[0015] The beneficial effects of adopting the above-mentioned further technical solution are as follows: By setting a controller and a first or second drive mechanism, the baffle can be easily slidably or rotatably installed at the output end of the frequency repair machine. This allows the baffle to automatically partially block, completely fold, or completely unblock the electron beam emitted from the output end of the frequency repair machine, thereby realizing the opening and closing of the electron beam of the frequency repair machine. This improves automation, reduces the labor intensity of users, and enhances the applicability of the local frequency repair device.

[0016] Furthermore, when the baffle is slidably installed at the output end of the frequency repair machine, the baffle is slidably installed at the output end of the frequency repair machine through a sliding mechanism, and the first driving mechanism is an electric push rod, a cylinder, or a hydraulic cylinder; when the baffle is rotatably installed at the output end of the frequency repair machine, the baffle is rotatably installed at the output end of the frequency repair machine through a rotating shaft, and the second driving mechanism is a motor.

[0017] The beneficial effects of adopting the above-mentioned further technical solution are as follows: The baffle is slidably installed at the output end of the frequency repair machine via a sliding mechanism or rotatably installed at the output end of the frequency repair machine via a rotating shaft. This facilitates the sliding or rotating of the baffle, prevents baffle wobbling, improves the stability and reliability of the baffle, reduces costs, and simplifies the structure. The ease with which the baffle is slidably or rotatably installed at the output end of the frequency repair machine allows for automatic partial blocking, complete folding, or complete unblocking of the electron beam emitted from the output end of the frequency repair machine, thereby realizing the opening and closing of the electron beam of the frequency repair machine. This also improves automation, reduces the labor intensity of users, and enhances the applicability of the local frequency repair device.

[0018] Furthermore, the present invention also provides a local frequency correction method. Based on the aforementioned local frequency correction device, the local frequency correction method includes: placing the product to be corrected on a frequency correction machine; selecting a template compatible with the product to be corrected based on the product to be corrected and the frequency correction area on the product; placing the template close to the surface of the product to be corrected and adjusting the template to block the non-frequency correction area in the product to be corrected; starting the frequency correction machine and opening and closing the electron beam of the frequency correction machine through a baffle, so that the electron beam corrects the frequency correction area in the product to be corrected.

[0019] The beneficial effects of adopting the technical solution of this invention are as follows: By designing a baffle for controlling the electron beam switch for frequency repair and a flexibly replaceable template adapted to the product to be repaired, the electron beam's effective area can be precisely controlled through the cooperation of the template and the baffle, effectively avoiding damage to non-repaired areas of the product, improving the accuracy of frequency repair, and ensuring product quality. It solves the problem of easily damaged peripheral parts during the frequency repair process for various products requiring localized frequency repair, improving the accuracy and applicability of frequency repair.

[0020] Further, the step of placing the product to be repaired on the repair machine includes: placing a square surface-mount device with a side length of 3mm on the worktable of the repair machine, and fixing the position of the square surface-mount device with a clamp; the step of selecting a template suitable for the product to be repaired based on the product to be repaired and the area to be repaired on the product to be repaired includes: selecting a square template with a square opening with a side length of 1.5mm in the center based on the size and shape of the chip to be repaired on the square surface-mount device; the step of placing the template close to the surface of the product to be repaired and adjusting the template to cover the non-repaired area in the product to be repaired includes: The process involves placing a square template close to the surface of the product to be repaired, adjusting the template so that the square opening on the template aligns with the chip to be repaired on the square surface-mount device, and ensuring that the template blocks the non-repaired area of ​​the product. The steps of starting the repair machine and opening / closing the electron beam of the repair machine via a baffle to repair the repaired area of ​​the product include: starting the repair machine, controlling the first or second drive mechanism via a controller to move the baffle, thereby opening and closing the electron beam of the repair machine; when the electron beam of the repair machine passes through the square opening on the template, the chip to be repaired is frequency-adjusted according to preset parameters, thus achieving frequency repair.

[0021] The beneficial effects of adopting the above-mentioned further technical solution are as follows: A small surface-mount device (approximately 3×3mm) to be repaired is stably placed on the worktable of the frequency repair machine, and its position is secured using clamps and other devices. Based on the size and shape of the chip to be repaired, a template with a 1.5mm×1.5mm square opening in the center is selected and carefully placed close to the device surface, ensuring precise alignment between the template opening and the 1.5mm×1.5mm chip area inside the device. The frequency repair machine is started, and the baffle intelligently controls the opening and closing of the electron beam according to the preset frequency repair program. When the electron beam passes through the small square hole in the template as instructed, the frequency of the chip surface is adjusted according to predetermined parameters.

[0022] Furthermore, after the step of starting the frequency repair machine and opening and closing the electron beam of the frequency repair machine through the baffle so that the electron beam repairs the frequency repair area in the product to be repaired, the following steps are included: after the frequency repair is completed, the frequency repair machine is turned off; the repaired product is removed, and the frequency repair effect of the product is tested.

[0023] The beneficial effect of adopting the above-mentioned further technical solution is that after the frequency repair task is completed, the frequency repair machine is turned off, the repaired device is carefully removed, and sent to the subsequent testing process to ensure that the frequency repair effect meets the product quality standards.

[0033] In the description of the embodiments of the present invention, it should also be noted that, unless otherwise explicitly specified and limited, the terms "set," "install," "connect," and "link" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in the present invention according to the specific circumstances.

[0034] This invention provides a local frequency repair device, comprising: a frequency repair machine, a baffle for opening and closing the electron beam of the frequency repair machine, and a template for blocking non-frequency repair areas in the product to be repaired. The baffle is movably mounted on the output end of the frequency repair machine, and the template is adapted to the product to be repaired.

[0035] The beneficial effects of adopting the technical solution of this invention are as follows: By designing a baffle for controlling the electron beam switch for frequency repair and a flexibly replaceable template adapted to the product to be repaired, the electron beam's effective area can be precisely controlled through the cooperation of the template and the baffle, effectively avoiding damage to non-repaired areas of the product, improving the accuracy of frequency repair, and ensuring product quality. It solves the problem of easily damaged peripheral parts during the frequency repair process for various products requiring localized frequency repair, improving the accuracy and applicability of frequency repair.

[0036] This invention aims to overcome the limitations of existing technology and provide a local frequency correction device and method. It can solve the problem that the peripheral parts of various products that require local frequency correction are easily damaged during the frequency correction process, thereby improving the accuracy and applicability of frequency correction.

[0037] Furthermore, the product to be repaired is a square surface-mount device with a side length of 3mm. The product to be repaired has a square chip with a side length of 1.5mm. The template is a square template with a square opening with a side length of 1.5mm in the center, so that the template can be adapted to the product to be repaired.

[0038] The beneficial effects of adopting the above-mentioned further technical solution are as follows: For micro-surface-mount devices with a size of 3×3mm that require frequency repair of 1.5mm×1.5mm chips, a square template with a 1.5mm×1.5mm opening in the center can be selected. This facilitates the selection of a suitable template based on the shape and size of the repair area of ​​the product to be repaired, and makes it easier for the template to be adapted to the product to be repaired.

[0039] Furthermore, the template is square, circular, triangular, rectangular, trapezoidal, or rhomboid in shape; the center of the template is provided with a square opening, circular opening, triangular opening, rectangular opening, trapezoidal opening, or rhomboid opening; the frequency repair machine is provided with a workbench for placing the product to be repaired and a clamp for fixing the product to be repaired.

[0040] The beneficial effects of adopting the above-mentioned further technical solution are: the template shape is not limited and can be any shape such as square, circle, or triangle, and the size can also be adjusted according to actual product requirements. It facilitates the selection of a suitable template based on the shape and size of the repair area of ​​the product to be repaired. It also facilitates template compatibility with the product to be repaired. If the product is different and a circular area needs repair, a template with a corresponding circular opening in the center can be used instead.

[0041] Furthermore, the shape and size of the template are adapted to the product to be repaired, the product to be repaired has a chip to be repaired, and the center of the template has an opening, the shape and size of which are adapted to the chip to be repaired.

[0042] The beneficial effects of adopting the above-mentioned further technical solution are: frequency correction is only performed on the specific area of ​​the product that needs frequency correction when the electron beam passes through the opening of the corresponding shape and size on the template. This allows the electron beam to be precisely confined within the target frequency correction area of ​​the product, effectively avoiding unnecessary damage to surrounding parts, providing strong support for the smooth progress of subsequent processes, and significantly improving the frequency correction quality and production efficiency of various products.

[0043] Furthermore, the baffle is slidably installed at the output end of the frequency repair machine, or the baffle is rotatably installed at the output end of the frequency repair machine.

[0044] The beneficial effects of adopting the above-mentioned further technical solution are: the baffle is slidably or rotatably installed at the output end of the frequency repair machine, which facilitates the baffle to partially block, completely fold, or completely unblock the electron beam emitted by the output end of the frequency repair machine, thereby realizing the opening and closing of the electron beam of the frequency repair machine. This improves the applicability of the local frequency repair device.

[0045] Furthermore, when the baffle is slidably installed at the output end of the frequency repair machine, the output end of the frequency repair machine is equipped with a first driving mechanism for driving the baffle to slide, the first driving mechanism is connected to the baffle, and the first driving mechanism is connected to a controller; when the baffle is rotatably installed at the output end of the frequency repair machine, the output end of the frequency repair machine is equipped with a second driving mechanism for driving the baffle to rotate, the second driving mechanism is connected to the baffle, and the second control mechanism is connected to a controller.

[0046] The beneficial effects of adopting the above-mentioned further technical solution are as follows: By setting a controller and a first or second drive mechanism, the baffle can be easily slidably or rotatably installed at the output end of the frequency repair machine. This allows the baffle to automatically partially block, completely fold, or completely unblock the electron beam emitted from the output end of the frequency repair machine, thereby realizing the opening and closing of the electron beam of the frequency repair machine. This improves automation, reduces the labor intensity of users, and enhances the applicability of the local frequency repair device.

[0047] Furthermore, when the baffle is slidably installed at the output end of the frequency repair machine, the baffle is slidably installed at the output end of the frequency repair machine through a sliding mechanism, and the first driving mechanism is an electric push rod, a cylinder, or a hydraulic cylinder; when the baffle is rotatably installed at the output end of the frequency repair machine, the baffle is rotatably installed at the output end of the frequency repair machine through a rotating shaft, and the second driving mechanism is a motor.

[0048] The beneficial effects of adopting the above-mentioned further technical solution are as follows: The baffle is slidably installed at the output end of the frequency repair machine via a sliding mechanism or rotatably installed at the output end of the frequency repair machine via a rotating shaft. This facilitates the sliding or rotating of the baffle, prevents baffle wobbling, improves the stability and reliability of the baffle, reduces costs, and simplifies the structure. The ease with which the baffle is slidably or rotatably installed at the output end of the frequency repair machine allows for automatic partial blocking, complete folding, or complete unblocking of the electron beam emitted from the output end of the frequency repair machine, thereby realizing the opening and closing of the electron beam of the frequency repair machine. This also improves automation, reduces the labor intensity of users, and enhances the applicability of the local frequency repair device.

[0049] The sliding mechanism can be a combination of a slide groove and a slide rail, or a combination of a guide rod and a guide block. When the baffle is rotatably installed at the output end of the frequency repair machine, the rotating shaft can be perpendicular to the axis of the output end of the frequency repair machine, so that the baffle rotates along the axis of the output end of the frequency repair machine; or the rotating shaft can be parallel to the axis of the output end of the frequency repair machine, so that the baffle rotates along the axis perpendicular to the output end of the frequency repair machine.

[0050] This innovative improvement upon traditional frequency repair machines adds a baffle for precise control of the electron beam switch and a series of custom-designed, interchangeable templates. These templates are not limited in shape; they can be square, round, triangular, or any other shape, and their size can be adjusted according to actual product requirements. For example, for micro-surface-mount devices approximately 3×3mm in size requiring frequency repair of a 1.5mm×1.5mm chip, a square template with a 1.5mm×1.5mm opening in the center can be used. If the product is different and requires repair of a circular area, a template with a corresponding circular opening in the center can be used. During frequency repair, the appropriate template is first selected based on the shape and size of the area to be repaired. The template is then placed tightly against the product surface, and the baffle strictly controls the electron beam's on / off state according to a pre-set program. Frequency repair is only performed on the specific area of ​​the product requiring repair when the electron beam passes through the corresponding opening of the template. In this way, the electron beam can be precisely confined within the target frequency correction area of ​​the product, effectively avoiding unnecessary damage to surrounding parts, providing strong support for the smooth progress of subsequent processes, and significantly improving the frequency correction quality and production efficiency of various products.

[0051] By adding a baffle to a traditional frequency repair machine to control the electron beam switch, and equipping it with a custom template of any shape and size that can be flexibly replaced, the template can be precisely selected according to product requirements, thereby achieving precise limitation of the electron beam's effective area and completing local frequency repair for various products.

[0052] This invention provides a combination structure of a baffle and a replaceable special template in a frequency correction device, and their collaborative working method. The frequency correction method based on this device covers a series of operational steps, including product placement, template selection and alignment, electron beam control, and post-frequency correction processing. It also demonstrates the application of this universal frequency correction technology to local frequency correction of different products, achieving the following technical effects: 1. Wide applicability: Not limited to surface-mount devices, it can be applied to any product that requires local frequency correction, greatly expanding the application scope of frequency correction technology.

[0053] 2. Precise frequency correction: Through the combination of a special template and baffle, the electron beam action area is precisely controlled, effectively avoiding damage to non-frequency correction areas of the product, improving frequency correction accuracy, and ensuring product quality.

[0054] 3. Flexible adjustment: The template can be changed at any time according to product needs, and the shape and size can be selected at will. It can quickly adapt to the frequency repair requirements of different products, improve production efficiency, and reduce production costs.

[0055] As an alternative to the aforementioned baffle-controlled electron beam, the electron beam's effective area can be controlled more precisely using magnetic fields, electric fields, and other methods.

[0056] like Figure 1 As shown, in addition, the present invention also provides a local frequency correction method. Based on the aforementioned local frequency correction device, the local frequency correction method includes: placing the product to be corrected on a frequency correction machine; selecting a template compatible with the product to be corrected based on the product to be corrected and the frequency correction area on the product; placing the template close to the surface of the product to be corrected and adjusting the template to block the non-frequency correction area in the product to be corrected; starting the frequency correction machine and opening and closing the electron beam of the frequency correction machine through a baffle, so that the electron beam corrects the frequency correction area in the product to be corrected.

[0057] The beneficial effects of adopting the technical solution of this invention are as follows: By designing a baffle for controlling the electron beam switch for frequency repair and a flexibly replaceable template adapted to the product to be repaired, the electron beam's effective area can be precisely controlled through the cooperation of the template and the baffle, effectively avoiding damage to non-repaired areas of the product, improving the accuracy of frequency repair, and ensuring product quality. It solves the problem of easily damaged peripheral parts during the frequency repair process for various products requiring localized frequency repair, improving the accuracy and applicability of frequency repair.

[0058] Further, the step of placing the product to be repaired on the repair machine includes: placing a square surface-mount device with a side length of 3mm on the worktable of the repair machine, and fixing the position of the square surface-mount device with a clamp; the step of selecting a template suitable for the product to be repaired based on the product to be repaired and the area to be repaired on the product to be repaired includes: selecting a square template with a square opening with a side length of 1.5mm in the center based on the size and shape of the chip to be repaired on the square surface-mount device; the step of placing the template close to the surface of the product to be repaired and adjusting the template to cover the non-repaired area in the product to be repaired includes: The process involves placing a square template close to the surface of the product to be repaired, adjusting the template so that the square opening on the template aligns with the chip to be repaired on the square surface-mount device, and ensuring that the template blocks the non-repaired area of ​​the product.

[0059] The beneficial effects of adopting the above-mentioned further technical solution are as follows: A small surface-mount device (approximately 3×3mm) to be repaired is stably placed on the worktable of the frequency repair machine, and its position is secured using clamps and other devices. Based on the size and shape of the chip to be repaired, a template with a 1.5mm×1.5mm square opening in the center is selected and carefully placed close to the device surface, ensuring precise alignment between the template opening and the 1.5mm×1.5mm chip area inside the device. The frequency repair machine is started, and the baffle intelligently controls the opening and closing of the electron beam according to the preset frequency repair program. When the electron beam passes through the small square hole in the template as instructed, the frequency of the chip surface is adjusted according to predetermined parameters.

[0060] Furthermore, after the step of starting the frequency repair machine and opening and closing the electron beam of the frequency repair machine through the baffle so that the electron beam repairs the frequency repair area in the product to be repaired, the following steps are included: after the frequency repair is completed, the frequency repair machine is turned off; the repaired product is removed, and the frequency repair effect of the product is tested.

[0061] The beneficial effect of adopting the above-mentioned further technical solution is that after the frequency repair task is completed, the frequency repair machine is turned off, the repaired device is carefully removed, and sent to the subsequent testing process to ensure that the frequency repair effect meets the product quality standards.

[0063] Based on the size and shape of the chip that needs frequency correction, select a template with a 1.5mm×1.5mm square opening in the center, and carefully place it close to the surface of the device so that the opening of the template is precisely aligned with the 1.5mm×1.5mm chip area inside the device.

[0064] When the frequency correction machine is started, the baffle intelligently controls the opening and closing of the electron beam according to the preset frequency correction program. When the electron beam passes through the small square hole in the template as instructed, the frequency of the chip surface is adjusted according to the predetermined parameters.
