Description

Technical Field

[0002] In modern semiconductor manufacturing, it is crucial to ensure that each tested semiconductor chip (integrated circuit) meets the specification requirements. In order to screen defective products, improve product quality, and verify the functions and performance of chips, the industry usually uses flip-chip testing sockets for testing.

[0003] The basic principle of a flip-chip testing socket is as follows: open the flip of the testing socket, place the chip to be tested into it, then achieve electrical connection through the internal contacts or spring pins corresponding to the chip pins. Subsequently, close the flip and press down on the chip for positioning to ensure good contact. Finally, analyze various performance indicators of the chip, such as electrical characteristics, reliability, and stability, through externally connected testing instruments.

[0004] For each test, the operator needs to hold tweezers to take out the chip from the chip tray and then carefully place it into the testing socket. After the test, the chip is manually retrieved. The whole process is time-consuming and repetitive, lacking automation functions, unable to achieve continuous and batch chip testing, greatly affecting the overall testing efficiency, restricting the production line speed, and being unfavorable for large-scale production and quality control.

[0035] The staff places the chip tray with chips between two groups of conveying wheels 129, and then starts the dual-axis motor 1210. The output shaft above the dual-axis motor 1210 drives the conveying wheels 129 to rotate, and the output shaft below the dual-axis motor 1210 drives the disc 1211 to rotate. The disc 1211 drives the conveying wheels 129 to rotate through the connecting rod 1212. The two conveying wheels 129 facing each other front and back are driven by gears, so that all the conveying wheels 129 can rotate synchronously. The conveying wheels 129 convey the chip tray to the right and transport the chips to the lower part of the electric suction cup 11. Then, control the lead screw motor 127 to drive the first slider 126 to move leftward. The first slider 126 drives the push block 128 to move leftward. The inclined surface on the push block 128 will contact the contact plate 124 and push the contact plate 124 to move downward. The contact plate 124 drives the slide plate 122 to move downward, and the first spring 123 is compressed. The slide plate 122 drives the hexagonal sleeve 9 and the rotating plate 10 to move downward. The rotating plate 10 drives the electric suction cup 11 to move downward. When the electric suction cup 11 moves downward, it will contact the chip and suck the chip. Subsequently, control the lead screw motor 127 to drive the first slider 126 and the push block 128 to move rightward. The push block 128 no longer pushes the contact plate 124. Under the action of the first spring 123, the slide plate 122 moves upward. The slide plate 122 drives the hexagonal sleeve 9 and the rotating plate 10 to move upward. The rotating plate 10 drives the electric suction cup 11 to move upward and suck the chip out of the chip tray. At this time, control the output shaft of the stepping motor 6 to rotate 180 degrees. The output shaft of the stepping motor 6 drives the hexagonal rod 8 to rotate 180 degrees. The hexagonal rod 8 drives the hexagonal sleeve 9 and the rotating plate 10 to rotate 180 degrees. The rotating plate 10 drives the electric suction cup 11 to rotate 180 degrees. The electric suction cup 11 drives the chip to rotate 180 degrees and rotates the chip above the test seat body 2. Then, control the lead screw motor 127 to drive the first slider 126 and the push block 128 to move leftward. The push block 128 pushes the contact plate 124 to move downward. The contact plate 124 drives the electric suction cup 11 to move downward and places the chip on the test seat body 2 for automatic feeding. Then, control the lead screw motor 127 to drive the first slider 126 and the push block 128 to move rightward. The push block 128 no longer pushes the contact plate 124. Under the action of the first spring 123, the electric suction cup 11 moves upward to move the electric suction cup 11 away to avoid collision between the flip cover 3 and the electric suction cup 11. At this time, the push block 128 is still moving rightward. The push block 128 will drive the push plate 147 to move rightward. The inclined surface on the push plate 147 will contact the contact shaft 146 and push the contact shaft 146 to move forward. The contact shaft 146 drives the moving plate 145 to move forward. The moving plate 145 drives the second slider 142 to move forward, and the second spring 143 is compressed. The second slider 142 drives the pressing plate 144 and the U-shaped rod 15 to move forward. The pressing plate 144 will push the flip cover 3 to rotate downward so that the flip cover 3 presses the chip on the test seat body 2 and the torsion spring deforms. Subsequently, the U-shaped rod 15 will contact the switch of the test seat body 2.Press the switch of the test socket body 2 to turn on the test socket body 2 and test the chip. The data of the chip will be displayed on the multimeter 4. If the chip is qualified, the indicator light 5 is defective. On the contrary, if the chip is unqualified, the indicator light 5 will light up. The staff can judge whether the chip is qualified through the indicator light 5. After the test is completed, control the lead screw motor 127 to drive the first slider 126 and the push block 128 to move leftward. The push block 128 drives the push plate 147 to move leftward. The push plate 147 no longer pushes the contact shaft 146. Under the action of the second spring 143, the second slider 142 moves backward. The second slider 142 drives the pressing plate 144 and the U-shaped rod 15 to move backward. The pressing plate 144 no longer pushes the flip cover 3. Under the action of the torsion spring, the flip cover 3 rotates upward to reset. Subsequently, the U-shaped rod 15 presses the switch of the test socket body 2 again to turn off the test socket body 2. At this time, the push block 128 is still moving leftward. The push block 128 will push the electric suction cup 11 to move downward. The electric suction cup 11 moves downward and contacts the chip on the test socket body 2 and sucks the chip on the test socket body 2. Then control the lead screw motor 127 to drive the first slider 126 and the push block 128 to move rightward. The push block 128 no longer pushes the electric suction cup 11. The electric suction cup 11 moves upward and sucks out the chip from the test socket body 2 for automatic blanking. If the chip is qualified, control the output shaft of the stepping motor 6 to rotate 180 degrees to rotate the tested chip above the chip tray and put the tested chip back into the chip tray. On the contrary, if the chip is unqualified, control the output shaft of the stepping motor 6 to rotate 90 degrees to rotate the tested chip above the collection box 13 and put the tested chip into the collection box 13 for collection for subsequent centralized processing. Repeating this operation can continue to test the chips, automatically and continuously test the chips, improve the overall test efficiency, and is beneficial to large-scale production.
