Abstract
Description
Technical Field
[0001] The present invention relates to the technical field of semiconductor chip production and packaging equipment, and in particular to a packaging device for semiconductor chip production. Background Art
[0002] Semiconductor packaging refers to the process of converting tested wafers into individual chips according to product model and functional requirements. The packaging process involves dicing wafers from the front-end wafer process into small dies. These dies are then glued onto the corresponding islands on the substrate (lead frame). Ultra-fine metal (gold, tin, copper, and aluminum) wires or conductive resin are then used to connect the die's bonding pads to the corresponding leads on the substrate, forming the required circuit. The individual dies are then encapsulated and protected in a plastic casing. A series of operations are performed after encapsulation, and the finished product is tested. The final steps typically include incoming inspection, testing, and packaging, before being shipped.
[0003] Semiconductor chip production packaging is the process of encapsulating manufactured semiconductor chips in a protective shell to provide physical protection, electrical connection and thermal management functions. During this process, the substrate needs to be moved and packaged to allow sampling inspection of the process flow, and the chip and packaging material need to be moved and spliced. Since the chip material is relatively fragile, certain accidental damage will occur during the equipment transfer and handling process, which reduces the yield rate to a certain extent. In addition, due to the mismatch in the thermal expansion coefficients of the chip and the substrate, during the mounting and heating process, the material contacts the high-temperature point, while the temperature of the rest of the material is low and the temperature distribution is uneven, which will cause more thermal stress accumulation, which may cause the chip or substrate to deform and crack, affecting the packaging reliability. Based on this, a packaging device for semiconductor chip production is proposed. Summary of the Invention

[0019] Compared with the prior art, the beneficial effects of the present invention are as follows: 1. When the device is in use, the material to be packaged is placed next to the test bench, and then after the equipment is started, the servo motor first rotates to drive the ball screw to rotate, and applies a spiral transmission force to the moving seat, and the moving seat moves under the sliding limit of the slide rail, and then drives the mechanical arm mechanism to move through the moving seat, and adjusts the range of the lifting mechanism to the inside of the material placement container outside the test bench. At this time, the electric control telescopic rod second extends and drives the inner sleeve column to move downward, prompting the rotating support mechanism and the suction mechanism to move downward, and the silicone at the bottom of the suction mechanism is sucked in. When the soft cone head contacts the chip material, the electric telescopic rod 5 retracts, driving the sealing piston to move upward, forming a negative pressure inside the installation cavity and the connecting branch pipe, and causing the rubber elastic diaphragm to deform and convex upward. Then the air pressure is transmitted to the bottom of the rubber elastic diaphragm of the air intake shell, causing the soft cone head of the silicone air intake soft cone head to contact the chip material and form an adsorption force on the chip. Then the electric telescopic rod 2 moves upward, and the moving mechanism and the mechanical arm mechanism are reset, placing the chip material on the inner side of the packaging mold seat, making it convenient for operators to pick up and place packaging inspections. The overall structure is stable and convenient for picking up and placing materials at multiple angles.
[0020] 2. The silicone suction soft cones are evenly arranged to disperse the air pressure adsorption force through multiple silicone suction soft cones, reducing the concentrated adsorption force on fragile chip materials, avoiding local stress concentration, and indirectly protecting the chip materials. In addition, the flexible cone shape of the silicone suction soft cone produces a certain deformation, ensuring the stability of adsorption. The flexible rounded corners will not damage the chip materials, thereby increasing the protection of the packaging operation, and can adapt to a variety of chip materials, increasing the relative stability and safety of the structure.
[0021] 3. When the two-way equivalent air outlet fan is started, the airflow enters the interior of the semi-annular seat through the connecting hose and enters the interior of the annular shell through the guide of the air outlet hose. The airflow is heated by the action of the electric heating wire and then discharged through the air outlet. The airflow is divided into two parts through the connecting hose to the air outlet hose and then to the air outlet, and the two parts are divided into circumferential guides, thereby achieving uniform discharge of the airflow. When the two-way equivalent air outlet fan blows in the opposite direction, the airflow enters through the air outlet. At this time, the chip package is pin-welded, generating a certain amount of smoke. The airflow brings the smoke out and enters the air outlet hose through the air outlet and the guide of the annular shell, and enters the interior of the semi-annular seat through the guide of the air outlet hose. Finally, it is filtered through the smoke filter, thereby filtering the smoke and avoiding the smoke affecting the operator and the visual system, ensuring the stability of welding, the overall ease of use, improving the yield rate and improving the product testing efficiency.

[0039] The working principle of the above technical solution is as follows: when in use, the material to be packaged is placed next to the test bench 1, and then after the equipment is started, the servo motor 204 rotates first to drive the ball screw 201 to rotate, and applies a spiral transmission force to the moving seat 205, and the moving seat 205 moves under the sliding limit of the slide rail 202, and then drives the mechanical arm mechanism 3 to move through the moving seat 205, and adjusts the range of the lifting mechanism 4 to the inside of the material placement container outside the test bench 1. At this time, the electric telescopic rod 2 406 extends and drives the inner sleeve column 402 to move downward, prompting the rotating support mechanism 9 and the suction mechanism 10 to move downward, and the silicone suction soft cone head 1002 at the bottom of the suction mechanism 10 contacts the chip.

The overall structure is stable to use and is convenient for taking and placing materials at multiple angles.
[0040] In another embodiment, Figures 1-4 As shown, the servo motor 204 is fixedly mounted on the top of the test bench 1 , the bottoms of the two slide rails 202 are fixedly mounted on the top of the test bench 1 , and the moving seat 205 is slidably sleeved on the outer sides of the slide rails 202 .
[0041] After the servo motor 204 is fixed, it is convenient to drive the ball screw 201 to rotate, thereby ensuring the stable coordinated movement of the mechanism, and facilitating the stable movement of the moving seat 205, thereby ensuring the operation of the mechanism.
[0042] In another embodiment, Figures 1-4 As shown, the robotic arm mechanism 3 includes a support column 304, and the outer side of the bottom end of the support column 304 is movably sleeved with a bearing support seat 307, and the bearing support seat 307 is fixedly installed on the top of the moving seat 205. The outer side of the support column 304 is fixedly sleeved with a driven transmission gear 303, and the outer side of the driven transmission gear 303 is engaged with a driving transmission gear 302. The bottom of the driving transmission gear 302 is transmission-connected with a servo motor 2 301, and the servo motor 2 301 is fixedly installed on the top of the moving seat 205. The top end of the support column 304 is rotatably hinged with a cross bar 305, and the outer side of the cross bar 305 is rotatably hinged with an electric-controlled telescopic column 1 306, and the end of the electric-controlled telescopic column 1 306 away from the cross bar 305 is rotatably hinged on the outer side of the support column 304.
[0043] The robotic arm mechanism 3 moves along with the moving mechanism 2. At this time, the servo motor 2 301 starts to rotate to drive the active transmission gear 302 to rotate, and the active transmission gear 302 drives the driven transmission gear 303 to rotate, and drives the support column 304 to rotate. The support column 304 rotates under the support of the bearing support seat 307, and drives the lifting mechanism 4 to leave the moving range of the test bench 1, which is convenient for driving and adjusting the rotation angle of the lifting mechanism 4, thereby cooperating with the moving mechanism 2 to drive the lifting mechanism 4 to move, which is convenient for coordinated operation.

[0045] The outer sleeve 401 cooperates with the movement of the cross bar 305, and the extension and retraction of the electric-controlled telescopic rod 2 406 facilitates the up and down movement of the inner sleeve column 402.

[0047] After the electric-controlled telescopic rod 1201 is extended, it drives the sealing piston 1202 to move, thereby forming an air pressure diversion inside the installation cavity 403, which is convenient for changing the air pressure and facilitating adsorption. When the sealing piston 1202 moves, the internal and external air pressures are connected through the pressure-equalizing air hole 405 and the guide air channel 404, thereby stabilizing the structural operation and avoiding the situation of poor air pressure diversion.

The ball grooves 903 and the rolling balls 904 are evenly distributed on the inner side of the support block 902 in a circular shape, and the bottoms of the support block 902, the ball grooves 903 and the rolling balls 904 are all in sliding contact with the top of the support ring plate 906.
[0049] When the inner sleeve column 402 moves in a telescopic manner, it will drive the support ring plate 906 to move, and then drive the rotation support mechanism 9 to move partly. The rolling ball 904 rolls inside the ball groove 903, thereby cooperating with the support block 902 to form a rotation support for the top of the support ring plate 906, so as to maintain a relatively stable rotation support effect, cooperate with the active rotation mechanism 11 to move, and maintain the relative stability of the structure.
[0050] In another embodiment, Figures 4-10 As shown, the connecting branch pipe 1004 is fixedly sleeved on the inner side of the rotating shell 901, the top end of the connecting branch pipe 1004 is rotatably inserted into the inner side of the mounting cavity 403, the mounting ring 1006 is movably sleeved on the inner side of the mounting cavity 403, the sealing cone ring 1007 is fixedly mounted on the inner side of the mounting cavity 403, the bottom of the rotating seal 1005 is in rotational sealing contact with the top of the connecting branch pipe 1004, and the silicone air-inhalation soft cone head 1002 is evenly distributed on the circumference of the bottom of the air-inhalation shell 1001. The silicone air-inhalation soft cone head 1002 is conical, and the outer edge of the bottom is provided with a rounded corner.
[0051] The rotating seal 1005, the mounting ring 1006 and the sealing cone ring 1007 are used to achieve the effect of rotating sealing of the connecting branch pipe 1004 and the inner wall of the mounting cavity 403, so as to maintain a relatively stable effect, maintain a flexible extrusion rotating seal, thereby stabilizing the airtightness and maintaining the air pressure operation effect. The silicone air-absorbing soft cone head 1002 is evenly arranged to promote the dispersion of the air pressure adsorption force through multiple silicone air-absorbing soft cone heads 1002, thereby reducing the concentrated adsorption force on fragile chip materials, avoiding the concentration of local stress, and indirectly protecting the chip materials. In addition, the flexible cone shape of the silicone air-absorbing soft cone head 1002 produces a certain deformation, which ensures the stability of adsorption, and the flexible fillet will not damage the chip material, thereby increasing the protection of the packaging operation, and can adapt to a variety of chip materials, increasing the relative stability and safety of the structure.
