Description
Technical Field
[0001] This invention relates to the field of chip packaging testing, and more particularly to a chip packaging testing system and its testing method. Background Technology
[0002] The casing used to house semiconductor integrated circuit chips serves to place, fix, seal, and protect the chip, enhance its electrical and thermal performance, and act as a bridge between the chip's internal world and external circuits—the contacts on the chip are connected to the pins of the package by wires, and these pins, in turn, connect to other devices via wires on the printed circuit board. Therefore, packaging plays a crucial role in CPUs and other LSI integrated circuits. During the chip packaging process, it is necessary to inspect the packaging quality, such as performing pressure tests on the packaged chip to check its strength.
[0003] In existing technologies, chip packaging is typically tested manually or using simple machinery, requiring multiple tests to complete the entire inspection process. This results in low automation, consuming significant manpower and yielding unsatisfactory test results. There is no cyclical, continuous, efficient, or intelligent testing process, and the test results are not intuitive. Therefore, we propose a chip packaging testing system and its testing method. Summary of the Invention

The system has a compact structure, and the items to be tested can be installed and replaced as needed. The testing process is cyclical, continuous, efficient, and intelligent. After testing, qualified and unqualified products are sorted and collected. The test results are intuitive, facilitating classification and statistical analysis, and improving testing efficiency.

[0014] This invention further proposes a testing method for the above-mentioned chip packaging testing system, the steps of which are as follows:
[0015] S1. Select the required testing equipment and install it at the end of the cylinder's three telescopic rod in the two sets of testing chambers; install the adsorption equipment at the end of the cylinder's three telescopic rod in the feeding chamber and discharging chamber.
[0016] S2. Place the packaged chips to be tested into the feed box;

The structure is compact, and the items being tested can be installed and replaced as needed. The testing process is cyclical, continuous, efficient, and intelligent. After testing, qualified and unqualified products are sorted and collected. The test results are intuitive, facilitating classification and statistics, and improving testing efficiency. During testing, two sets of translation frames move backwards, opening the inlet / outlet channels. The adsorption device extends into the feeding box, adsorbing the topmost chip into the testing chamber. The translation frames then move forwards, closing the inlet / outlet channels. Simultaneously, the chip is placed on the horizontal section of the translation frames. Positioning components on both sides clamp and fix the chip. The opening and closing of the inlet / outlet channels and the placement and clamping of the positioning components are synchronized using the sliding control of the translation frames. This ensures efficient and stable material handling and fixing, facilitating subsequent testing. Attached Figure Description

Through the transmission of the second motor 24, the first gear 22 and the second gear 23 are driven to rotate, ultimately achieving the rotation of the rotating disk 17. This facilitates adjusting the chip angle during detection, resulting in more comprehensive detection.
[0059] like Figure 6 As shown, each testing station is equipped with a pusher component 32; the pusher component 32 includes a second cylinder 30 and a pusher plate 31. The second cylinder 30 is mounted on the lower separator 7, and the pusher plate 31 is mounted on the telescopic rod, allowing it to move horizontally between the two sets of translation frames 19. When the test result is unqualified, the pusher plate 31 is driven to move horizontally by the second cylinder 30, pushing the chip on the translation frame 19 to the push port, where it falls into the unqualified product discharge box 4. Qualified products enter the qualified product discharge box 3, automatically completing the sorting process.
[0060] Furthermore, guide rods 28 are provided on both sides of the inlet / outlet slot 18; the two ends of the guide rods 28 are slidably connected to the corresponding translation frames 19, and the middle end is provided with an anti-slip locking sleeve 29; the horizontal section of the translation frame 19 is provided with a locking groove that matches the locking sleeve 29. The translation frame 19 moves along the guide rods 28 with a stable trajectory. When the two sets of translation frames 19 approach each other, the locking sleeve 29 engages with the locking grooves on both sides, providing more stable support for the chip.
[0061] Furthermore, the positioning component 20 includes a spring 26 and a positioning rod 27; a mounting hole is provided at the bottom of the vertical section of the translation frame 19; the spring 26 is disposed in the mounting hole; one end of the positioning rod 27 extends into the mounting hole and connects to the spring 26, and the other end is provided with a hemispherical positioning head. When the chip is placed on the vertical section of the translation frame 19, the positioning rods 27 on both sides gradually move closer to it until the chip is locked. The spring 26 pushes the positioning rod 27 to fix the chip firmly, ensuring its stability during the testing process.
[0062] like Figure 2-3As shown, the movable lifting component includes a motor 10, a lead screw 11, a moving block 12, and a cylinder 13. The motor 10 is mounted on the upper partition frame 8. The lead screw 11, driven by the motor 10, rotates within the feeding chamber 14, the discharging chamber 15, and the two sets of testing chambers 16. The moving block 12, threadedly connected to the lead screw 11, moves horizontally. The cylinder 13 is located at the lower end of the moving block 12, and its telescopic rod end is detachably connected to the adsorption / testing equipment. The motor 10 drives the lead screw 11 to rotate, causing the moving block 12 to move on the lead screw 11, which in turn drives the cylinder 13 to move horizontally. Simultaneously, the telescopic rod end of the cylinder 13 moves up and down, ultimately adjusting the position of the adsorption / testing equipment to meet the needs of feeding, testing, and discharging.
[0063] Example 6
[0064] This invention further proposes a testing method for the above-mentioned chip packaging testing system, the steps of which are as follows:
[0065] S1. Select the required testing equipment and install it at the end of the telescopic rod of cylinder 3 13 in the two sets of testing chambers 16; install the adsorption equipment at the end of the telescopic rod of cylinder 3 13 in the feeding chamber 14 and the discharging chamber 15.
[0066] S2. Place the packaged chip to be tested into the feed box 2;
[0067] S3, the rotating plate 6 rotates, the upper partition frame 8 and the lower partition frame 7 rotate relative to each other until the transmitter and receiver of each set of position sensors 9 sense the position; the positioning component 33 opposite to the feeding chamber 14 works, and the cylinder 1 21 drives the two sets of translation frames 19 to move backward, and the inlet and outlet channel 18 opens; the adsorption equipment, driven by the cylinder 3 13, passes through the opening, extends into the feeding box 2, and adsorbs the chip at the top to the detection chamber;
[0068] S4. The translation frame 19 moves to the opposite side, the inlet and outlet through slot 18 closes, and the positioning component 20 clamps and fixes the chip.
[0069] S5. The rotating plate 6 rotates, transferring the fixed chip to two sets of detection rooms 16 in sequence for various tests. During the test, the moving lifting component drives the detection equipment to move up and down and back and forth, while the driving component drives the rotating disk 17 to rotate, so as to comprehensively and multi-angle test the quality of chip packaging.
[0070] S6. After the test is completed, the fixed chip enters the discharge chamber 15. If it is a qualified product, the qualified chip is transferred to the qualified product discharge box 3 by opening the inlet and outlet channel. If it is a defective product, the pusher plate 31 pushes it into the pusher port and it falls into the defective product discharge box 4.
[0071] The embodiments of the present invention have been described in detail above with reference to the accompanying drawings. However, the present invention is not limited thereto. Various changes can be made within the scope of knowledge possessed by those skilled in the art without departing from the spirit of the present invention.
