Description

Technical Field

[0001] The present invention relates to the technical field of packaging and testing equipment for flip chips, and in particular to packaging and testing equipment for high-precision flip chips. Background Art

[0002] A flip chip is a pinless structure that generally contains circuit units and is designed to be electrically and mechanically connected to the circuit through an appropriate number of solder balls located on its surface. The chip is flipped over and heated, and then bonded to the ceramic substrate using molten solder-lead balls. This technology replaces conventional wire bonding. After the chips are packaged, they are individually quality-tested to eliminate defective products and improve the quality control of flip chips.

[0003] For example, the publication number CN116037494A, "A detection device and detection method based on flip chip packaging", the present invention controls the displacement of the transfer bracket so that it is located directly above the chip to be detected. After the transfer bracket clamps the chip, the chip is sent to the lower end of the detection mechanism, so that the chip is aligned with the detection component, thereby completing the detection work; when the detection result of the chip is qualified, the conveyor belt sends the chip to one side end of the conveyor plate exposed, and when the detection result of the chip is unqualified, the conveyor belt sends the chip to the other side end of the conveyor plate exposed, thereby facilitating the staff to classify and collect the detected chips, with high automation intensity, completing quality inspection during the chip transmission process, which is conducive to improving the detection work efficiency.

[0004] Although this type of flip-chip package detection equipment has improved the efficiency of chip detection, it is lacking in chip protection. Since this type of chip detection equipment clamps and fixes the chip through a clamping component and then transports it through a transfer structure, when the chip is clamped by the clamping component, if the clamping force of the clamping component is too small, the chip will become loose and fall during the transfer process, causing the chip to be damaged due to falling. If the force of the clamping component is too large, the chip will be clamped and damaged on the side in contact with the clamping component due to excessive clamping force, resulting in unnecessary losses. Summary of the Invention

[0005] The purpose of the present invention is to provide a packaging and testing device for high-precision flip-chips, so as to solve the problem of damage to chips during transportation due to uneven clamping force of the clamping components on the chips in the packaging and testing device for flip-chips proposed in the above background technology.

[0016] Compared with the prior art, the present invention has the following beneficial effects:

[0017] 1. In the present invention, the motor A drives the screw rod A to rotate. When the screw rod A rotates, it drives the limit block A to move inside the support plate A, and the limit block A drives the slider to slide on the bottom surface of the support plate A, thereby driving the support plate B to move laterally, and the support plate B drives the vacuum suction head to move laterally. At this time, the motor B is turned on again, and the motor B drives the gear shaft to rotate.

The vacuum adsorption design avoids the situation where the chip is clamped and damaged when the chip is fixed by the clamping structure.

[0018] 2. In the present invention, the motor C drives the screw rod B to rotate. When the screw rod B rotates, it drives the connecting plate A to slide inside the limiting groove. When the connecting plate A slides, it also drives the cleaning box to slide inside the fixed seat. At this time, the brush plate at the bottom of the cleaning box will clean the inner surface of the placement groove, and the dust raised by the cleaning will be sucked into the cleaning box by the exhaust fan B through the dust suction pipe. After passing through the filter element, the air will be discharged through the air outlet B, and the dust in the air will adhere to the inside of the filter element. When the filter element needs to be replaced, it is only necessary to rotate the insert. After the insert is rotated out of the cleaning box, the cover plate will be rotated by the torsion of the torsion spring. After the cover plate is turned open, the filter element inside the cleaning box can be replaced. The design of the brush plate and the exhaust fan B makes it easy to clean the inside of the placement groove, thereby preventing dust from adhering to the surface of the chip and affecting the accuracy of chip detection.

[0019] 3. In the present invention, the rotation of the bidirectional screw C is driven by the motor D, thereby driving the splint A and the splint B to slide on the surface of the limit rod A, so that the splint A and the splint B move toward each other, and correct and limit the chips on the conveyor belt, thereby preventing the occurrence of inaccurate positioning of the detection probe due to chip tilt. The connecting plate B is driven by the electric push rod C to slide on the surface of the limit rod B, thereby driving the push plate to slide inside the base. When the push plate moves, the chips that fail the inspection will be discharged from the base through the discharge port B through the U-shaped groove, and the chips that pass the inspection will be discharged by the conveyor belt through the discharge port A, thereby achieving the effect of sorting the chips after inspection, avoiding the need for staff to manually sort them after the inspection is completed.

[0035] In this embodiment, the motor C33 drives the screw rod B34 to rotate. When the screw rod B34 rotates, it drives the connecting plate A35 to slide inside the limiting groove 32.

[0039] The electric push rod C53 drives the connecting plate B54 to slide on the surface of the limit rod B52, thereby driving the push plate 55 to slide inside the base 1. When the push plate 55 moves, the chips that fail the inspection will be discharged from the base 1 through the discharge port B51 through the U-shaped groove 56, and the chips that pass the inspection will be discharged by the conveyor belt 3 through the discharge port A2, thereby achieving the effect of sorting the chips after inspection, avoiding the need for staff to manually sort them after the inspection is completed.

[0040] The usage and working principle of this device: before the chip needs to be tested, the chip needs to be placed in the feed port 5, and when transporting the chip, it is only necessary to turn on the motor A7, and the motor A7 will drive the screw rod A9 to rotate. When the screw rod A9 rotates, it will drive the limit block A10 to move inside the support plate A8, and the limit block A10 will drive the slider 11 to slide on the bottom surface of the support plate A8, thereby driving the support plate B14 to move horizontally, and the support plate B14 will drive the vacuum suction head 21 to move horizontally. At this time, turn on the motor B12, and the motor B12 will drive the gear shaft 13 to rotate. When the gear shaft 13 rotates, it will drive the support plate B14 to slide inside the slider 11 through the limit block B16, thereby driving the vacuum suction head 21 to move longitudinally, and then drive the electric push rod A18 to The vacuum suction head 21 is moved vertically, and then the exhaust fan A23 is turned on. The exhaust fan A23 will extract the air in the vacuum suction head 21 through the rubber hose 22, so that the chip is attached to the inner surface of the vacuum suction head 21. Then, by moving the support plate A8 and the support plate B14, the chip inside the vacuum suction head 21 can be placed on the surface of the conveyor belt 3 through the feed port 5. At this time, the conveyor belt 3 will transport the chip to the bottom of the detection probe 30, and then the electric push rod C53 will be turned on.

After the detection is completed, the chip can be discharged through the discharge port A2 through the conveyor belt 3.

[0041] When the dust in the placement slot 26 needs to be cleaned, it is only necessary to turn on the motor C33, and the motor C33 will drive the screw rod B34 to rotate. When the screw rod B34 rotates, it will drive the connecting plate A35 to slide inside the limiting slot 32. When the connecting plate A35 slides, it will also drive the cleaning box 36 to slide inside the fixing seat 25. At this time, the brush plate 41 at the bottom of the cleaning box 36 will clean the inner surface of the placement slot 26, and the dust raised by the cleaning will be sucked into the cleaning box 36 by the exhaust fan B37 through the dust suction pipe 40; after being filtered by the filter element 39, the air will be discharged through the air outlet B38, and the dust in the air will be discharged. Attached to the inside of the filter element 39, the dust inside the placement slot 26 is cleaned; when the filter element 39 needs to be replaced, it is only necessary to rotate the insert 45. After the insert 45 is rotated out of the cleaning box 36, the cover plate 44 will be rotated by the torsion force of the torsion spring 43. After the cover plate 44 is rotated open, the filter element 39 inside the cleaning box 36 can be replaced. The design of the brush plate 41 and the exhaust fan B37 facilitates the cleaning of the inside of the placement slot 26, thereby preventing dust from adhering to the surface of the chip and affecting the accuracy of chip detection, and also facilitates the replacement of the filter element 39.

[0042] When it is necessary to correct and limit the chip on the conveyor belt 3, it is only necessary to turn on the motor D46. The motor D46 will drive the rotation of the bidirectional screw rod C47, thereby driving the clamping plate A49 and the clamping plate B50 to slide on the surface of the limit rod A48. At this time, the clamping plate A49 and the clamping plate B50 will move towards each other inside the base 1, and correct and limit the chip on the conveyor belt 3, thereby preventing the detection probe 30 from being inaccurately positioned due to the tilt of the chip; when it is necessary to sort the chips after the detection is completed, Just open the electric push rod C53, the electric push rod C53 will drive the connecting plate B54 to slide on the surface of the limit rod B52, thereby driving the push plate 55 to slide inside the base 1, and when the push plate 55 moves, it will use the U-shaped groove 56 to discharge the unqualified chips from the base 1 through the discharge port B51, and the qualified chips will be discharged by the conveyor belt 3 through the discharge port A2, thereby achieving the effect of sorting the chips after inspection, avoiding the need for staff to manually sort them after the inspection is completed.
