Description

Technical Field

[0001] The present invention belongs to the technical field related to microwave packaging, and more specifically, particularly relates to a heating type automatic connector repair device. Background Art

[0002] In recent years, with the continuous development of radar technology, synthetic aperture radar has been vigorously developed by various countries due to its high penetration and high resolution, especially in the field of spaceborne radar. Among them, microwave transmitter and receiver components are one of the most important components of the radar system. The volume, weight, and electrical performance of the T / R components directly determine the various technical indicators of radar signal reception and transmission.

[0003] Among them, microwave chip T / R components, with their vertical three-dimensional stacking integrated assembly method, have the advantages of high integration, small size, and light weight compared to traditional brick-type T / R components. Traditional brick-type T / R components are plugged into external cables to achieve signal transmission, which requires a large number of cables for the entire array, making the entire radar array system structure complex and difficult to reduce weight. However, chip-type T / R components can be directly plugged into the signal transmission / receiving end through an adapter. The assembly method of the entire radar array system is optimized, making the assembly of the entire array system more convenient, and the weight and volume are greatly reduced. Therefore, chip-type T / R components are gradually replacing brick-type T / R components and becoming the first choice for spaceborne SAR.

[0004] Among them, the connector of the T / R component is used to connect with the external plug, connect the T / R component, and transmit the RF, power, and control signals inside and outside the TR component. The connector of the traditional brick-type T / R component is designed on both sides of the shell frame. The connector adopts a cylindrical pin structure. The connector is directly inserted into the shell and is fixed and sealed by solder. The connector of the chip-type T / R component is installed above or below the shell. The connector adopts a threaded button structure, which is screwed into the shell through the thread, and then filled with solder and sealed through the outer ring.

[0005] Among them, the connector installation and welding of the chip T / R assembly can be welded in the form of a reflow oven or a hot plate heating gun, but if disassembly is required, the above two methods cannot be completed. Since the connector is screwed into the shell through threads, it is reflowed and disassembled in a reflow oven, and the connector cannot be unscrewed manually or by equipment. Although the hot plate heating gun can achieve disassembly, it requires a long heating time or a very high heating temperature, and there is a risk of remelting the resistor component or circuit substrate, and the efficiency is very low, which can easily cause the T / R assembly to be scrapped.

[0006] The present invention provides a connector repair device and a repair method for a chip assembly, which can effectively reduce the risk of remelting of a resistor and capacitor component or a circuit substrate and have high efficiency. Summary of the invention

[0025] Compared with the prior art, the present invention has the following beneficial effects:

[0026] The installation of a heating automatic connector rework device of the present invention through the rework tool is a delicate process, which starts with the sleeve connection between the tool housing and the heat-conducting rod of the electric soldering iron. This key step ensures that heat can be efficiently transferred from the electric soldering iron to the rework tool, providing the necessary thermal energy for subsequent welding work. As a medium for heat energy transfer, the design of the heat-conducting rod must ensure rapid and uniform distribution of heat. Next, the fixed sleeve is sleeved outside the tool housing, which not only provides stable external support for the tool, but also guides the heat to be evenly transferred to various parts of the tool through its structural design. The use of the fixed sleeve enhances the mechanical stability of the entire tool, enabling it to maintain shape and size stability under high heat loads;

[0027] The heating type automatic connector repair device of the present invention is precisely threadedly connected with the thread block on the control body through the fixing nut. This tightening process firmly holds the fixing sleeve, ensuring the stable fixation of the tool housing on the heat conducting rod. This threaded connection method not only provides a strong clamping force, but also ensures the repeated positioning accuracy of the tool during operation through precise thread matching;

[0028] The heating type automatic connector repair device of the present invention is used to embed the steel sheet through the specially designed clamping groove at one end of the tooling shell. This embedding process not only enhances the structural rigidity of the tooling, but also provides key mechanical support for subsequent electromagnetic operations. The introduction of the electromagnet further improves the connection stability between the steel sheet and the tooling shell through its electromagnetic adsorption effect, ensuring accurate positioning during the welding process;

[0029] The heating type automatic connector repair device of the present invention can be connected to the threaded hole of the external shell through the threaded design of the metal threaded shell, and the steel sheet on the repair tool is used to align the groove on the outside of the metal threaded shell for rotation and positioning. This threaded installation method ensures that the button inside the button connector can fit tightly to the contact on the circuit substrate, providing a guarantee for achieving accurate electrical connection. This precise positioning and connection ensures the stability of the performance of the electronic equipment;

[0030] The heating automatic connector rework device of the present invention is integrated into the rework tooling through a thermal probe, which can monitor and transmit temperature data to the control screen in real time. This temperature monitoring mechanism is the key to preventing parts from being damaged due to excessive temperature during welding, ensuring the safety and reliability of welding operations. Through real-time temperature feedback, the operator can adjust the power output of the electric soldering iron in time to ensure that the welding process is carried out within the optimal temperature range;

[0031] Therefore, the above efficient rework system not only improves production efficiency and reduces rework costs, but also improves product reliability and life by reducing potential risks in the rework process. BRIEF DESCRIPTION OF THE DRAWINGS

[0051] As attached Figure 1 To Attachment Fig.14 As shown: The present invention provides a heating type automatic connector rework device, comprising a control body 1, a threaded block 21 and an external shell 5, an electric soldering iron 2 is arranged at one end of the control body 1, the threaded block 21 is a part of the electric soldering iron 2, a heat-conducting rod 22 is penetrated and connected inside the threaded block 21, a fixed sleeve 23 is sleeved on the outer side of the heat-conducting rod 22, the fixed sleeve 23 is threadedly connected to the threaded block 21 by a fixing nut 24 for fixing, a rework tool 3 is arranged inside the fixed sleeve 23, a wool button connector 4 is arranged inside the external shell 5, a circuit substrate 6 is installed inside the external shell 5, a solder groove 7 is opened inside the external shell 5, and a contact 8 is fixedly connected inside the external shell 5.

[0052] In this embodiment, first, one end of the rework tool 3 is firmly installed on the corresponding end of the heat-conducting rod 22, and then, the fixed sleeve 23 is evenly passed through the rework tool 3 and the heat-conducting rod 22 to ensure that the two are coaxially aligned. Furthermore, the fixing nut 24 on the outside of the fixed sleeve 23 is threadedly connected and tightly locked on the threaded block 21 at one end of the control body 1, so as to achieve stable fixation of the fixed sleeve 23 and the rework tool 3.

[0053] As a further technical solution, the rework tool 3 comprises a tool shell 31 , which is sleeved inside the fixed sleeve 23 and on the heat conducting rod 2 , and a clamping groove 32 is provided at the other end of the tool shell 31 .

[0054] In this embodiment, the tooling housing 31 ensures efficient heat transfer by accurately fitting on the thermal conductor 22. At the end of the housing 31, a special clamping groove 32 is configured, which is designed to achieve the installation of the steel sheet 35.

[0055] A further technical solution is that the radius of the clamping groove 32 decreases from the outside to the inside, an electromagnet 33 is embedded in the inner side of the clamping groove 32, a thermistor 34 is embedded in the inner side of the clamping groove 32, a steel sheet 35 is embedded in the inside of the clamping groove 32, and a control screen 36 is embedded in the outer surface of the control body 1.

[0056] In this embodiment, in the precision tooling design, an embedded part, namely a steel sheet 35, is specially designed on the inner side of the clamping groove 32 to enhance its structural stability. The electromagnet 33 installed in the groove can stably fix the steel sheet 35 by using the principle of magnetic adsorption, ensuring the precise positioning of the workpiece during the processing. In addition, in order to achieve real-time monitoring of the temperature of the tooling housing 31, a thermistor 34 is integrated near the clamping groove 32, which can transmit temperature data to the control screen 36. This design allows the operator to obtain instant temperature feedback through the control screen 36, ensuring that the processing process is carried out under precise temperature control, thereby optimizing the process flow and improving production efficiency.

[0057] A further technical solution, a heated automated connector rework device, is based on the following installation sequence:

[0058] C1, the rework tool 3 is installed on the heat conducting rod 22 of the electric soldering iron 2;

[0059] C2, the fixed sleeve 23 is inserted into the repair tool 3;

[0060] C3. The fixing nut 24 is inserted into the fixing sleeve 23 and threadedly connected with the threaded block 21 at the control body 1, thereby completing the assembly of the repair tool 3.

[0061] In this embodiment, first, the rework tool 3 needs to be precisely assembled onto the heat conducting rod 22 of the electric soldering iron 2 to achieve rapid heat transfer. Next, the fixed sleeve 23 is sleeved on the outside of the rework tool 3 to provide structural protection for the tool. Finally, the fixed nut 24 is tightened into the fixed sleeve 23 and fastened to the threaded block 21 of the control body 1 to complete the stable assembly of the rework tool 3. This series of orderly assembly steps ensures the precise positioning of the tool during the rework process and the reliability of operation.

[0062] A further technical solution is that the hair button connector 4 includes a metal threaded shell 41, which is threadedly connected to the inside of the external shell 5. The metal threaded shell 41 is a copper alloy with gold plating on the surface, is cylindrical, and has a threaded lower cylinder. A hair button 42 is fixedly installed inside the metal threaded shell 41, and an engineering plastic 43 is fixedly connected to the inside of the metal threaded shell 41. A metal lead pin 44 is fixedly installed inside the metal threaded shell 41.

[0063] In this embodiment, the button connector 42 and the metal pin 44 are embedded in the internal structure of the engineering plastic base 43, wherein a portion of the button connector 42 is designed as a protruding end to facilitate external connection to the engineering plastic base 43 through its external threaded structure to achieve precise threaded interconnection with the metal threaded shell 41, ensuring that the button connector 42 can maintain stable physical contact with the circuit substrate 6. This design allows the button connector 42 to effectively dock with the corresponding contacts 8 on the circuit substrate 6 in the external shell 5, thereby achieving precise transmission of signals between internal and external circuits. This assembly scheme not only ensures the reliability of the electrical connection, but also provides structural compactness and ease of operation.

[0064] According to a further technical solution, the wool button 42 and the metal guide pin 44 are both embedded in the engineering plastic 43 , and a groove 45 is formed on one side of the metal threaded shell 41 .

[0065] In this embodiment, the groove 45 is provided to facilitate separation of the button connector 4 from the external housing 5 .

[0066] A further technical solution is that the metal threaded shell 41 is threadedly installed and disassembled with the external shell 5, and the wool button 42 is formed by winding a gold-plated special copper alloy metal wire, which is in a twist shape and has a certain elasticity.

[0067] In this embodiment, the threaded connection between the metal threaded shell 41 and the external shell 5 increases the tightness between the wool button 42 and the circuit substrate 6 .

[0068] A further technical solution is a heating type automatic connector rework device, based on the following method:

[0069] S1, according to the assembly method of the rework tool 3, complete the assembly of the rework tool 3 and the electric soldering iron 2;

[0070] S2, heating the electric soldering iron 2 so that the measured temperature reaches 230-250°C;

[0071] S3, setting the temperature of the hot plate at 100-120°C, and after the temperature of the hot plate is stable, placing the T / R assembly of the button connector 4 to be removed on the hot plate for preheating;

[0072] S4, after the T / R assembly is preheated, the rework tool 3 is inserted into the button connector 4 to be removed, and the rework tool 3 is accurately aligned and embedded in the button connector 4;

[0073] S5, wait for 30-40 seconds until the solder around the button connector 4 melts, then use the soldering iron 2 to twist out the button connector 4 to complete the disassembly.

[0074] In this embodiment, the rework tool 3 is made of brass, which is very suitable for precision rework due to its good thermal conductivity and machining performance. The front end of the tool must be precisely matched with the inner groove of the button connector 4, while the rear end must be closely matched with the mounting sleeve of the electric soldering iron 2 to ensure effective heat transfer and stable installation of the tool. In terms of dimensional tolerance control, the following precise process parameters are followed: Fig.10 , Fig.11 , Fig.12 , Fig.13 and Fig.14As shown, parameters A and B: Based on the reference dimensions A1 and B1, add a tolerance range of 0.05 to 0.06 mm respectively, and the single-sided tolerance is controlled at 0.025 to 0.03 mm to ensure the flexibility of the connection and the appropriate fitting clearance. Parameter C: The size is set to C1 minus 1 mm, and the single-sided tolerance is controlled at 0.05 mm to ensure the mechanical strength of the rework device and avoid damage to the lead pins during the plug-in and pull-out process. Parameters D and E: The size should be consistent with D1 and E1 to ensure that the insertion depth of the rework device is accurately matched with the depth of the connector cavity. Parameter F: Based on F2, add a tolerance range of 0.05 to 0.06 mm, and the single-sided tolerance is controlled at 0.025 to 0.03 mm to ensure smooth plug-in and pull-out and moderate clearance. Parameter F1: Slightly smaller than F2, specifically F2 minus 0.02 mm, to achieve a firm fit between the steel sheet and the rework device. Parameter F3: Based on F2, the single-side tolerance of the size with an increase of 1mm is also controlled at 0.025-0.03mm. The opening of the rework device is designed with a groove to facilitate plug-in and pull-out operations, reduce damage to the lead pins, and facilitate the assembly of the steel sheet. Parameter G: Based on G1, minus 0.2-0.3mm, the single-side tolerance is controlled at 0.1-0.15mm to meet the gap requirements between the connector and the shell solder groove. Parameter H: The height of the steel sheet is designed to be slightly lower than the height H1 of the connector groove, specifically H1 plus 0.05mm, to avoid damaging the connector groove during insertion. There is no fixed requirement for the length L of the rework device, but the recommended length is controlled at 20-30mm to balance heat transfer efficiency and material cost. The inner diameter M of the sleeve should be slightly larger than the diameter of the soldering iron heat conducting rod, and the outer diameter N should be slightly smaller than the diameter of the soldering iron fixed sleeve. The tolerances of both are controlled within the range of 0.05-0.1mm to ensure tight fit and effective transfer of heat energy. Through these precise dimensional controls and design considerations, the Rework Tool 3 ensures reliability and efficiency during precision rework, while providing ease of operation and consistency in rework quality.

[0075] The specific method of using the present invention is as follows: First, the installation of the rework tool 3 starts with the sleeve connection between the tool housing 31 and the heat-conducting rod 22 of the electric soldering iron 2. This step is the basis for ensuring that the heat is effectively transferred from the electric soldering iron 2 to the rework tool 3. Next, the fixed sleeve 23 is sleeved outside the tool housing 31, and its function is to provide a stable external support for the tool and guide the heat to be evenly distributed. Subsequently, the fixed sleeve 23 is firmly pressed against the threaded block 21 on the control body 1 through the fixed nut 24, so that the tool housing 31 is stably fixed on the heat-conducting rod 22. This tightening process ensures the mechanical stability and structural integrity of the tool in a high-temperature working environment. One end of the tool housing 31 is specially designed. The clamping groove 32 is used to embed the steel sheet 35. This embedding process not only enhances the structural rigidity of the tooling, but also provides key mechanical support for subsequent electromagnetic operations. The introduction of the electromagnet 33 further improves the connection stability between the steel sheet 35 and the tooling shell 31 through its electromagnetic adsorption effect. During the assembly stage of the wool button connector 4, the metal threaded shell 41 is accurately aligned with the threaded hole of the external shell 5, and the steel sheet 35 on the rework tool 3 is used to align with the groove 45 on the outside of the metal threaded shell 41 for rotational positioning. This threaded installation method ensures that the wool button 42 inside the wool button connector 4 can fit tightly against the contact 8 on the circuit substrate 6, providing a precise electrical connection. To ensure that in the welding preparation stage, an appropriate amount of flux is added to the solder tank 7 to prepare for the subsequent welding operation. The start-up of the electric soldering iron 2 causes the heat on the heat-conducting rod 22 to be transferred to the rework tool 3, and then to the button connector 4, so that the flux melts. In this process, the button 42 is welded to the contact 8 on the circuit substrate 6 to establish a stable electrical connection. In order to monitor the temperature during the welding process, the thermistor 34 is integrated in the rework tool 3, which can monitor and transmit temperature data to the control screen 36 in real time. This temperature monitoring mechanism is the key to preventing damage to parts caused by excessive temperature during the welding process, ensuring the safety and reliability of the welding operation. During the rework process, if the button needs to be removed The button connector 4, first align the steel sheet 35 with the groove 45 on the outside of the metal threaded shell 41, start the electric soldering iron 2 again, and use the heat transferred by the heat-conducting rod 22 to melt the flux. When the flux is molten, the disassembly operation can be smoothly performed by twisting the button connector 4, thus realizing the versatility of the rework tool 3. The integrated system of the entire rework tool 3 and the electric soldering iron 2 provides an efficient and reliable rework solution through precise temperature control, mechanical positioning and structural stability. The design and application of this system significantly improves the efficiency and quality of semiconductor package rework operations, provides users with an efficient and reliable rework tool, and ensures the professionalism and precision of the electronic equipment repair process.
