Description

Technical Field

[0001] The present application belongs to the technical field of chip packaging equipment, and specifically relates to a chip tray detection device. Background Art

[0002] A chip is a silicon wafer containing an integrated circuit, which is manufactured on the surface of a semiconductor wafer. Chips need to be sampled during mass production, and arcs and solder balls need to be inspected before chip packaging to prevent arcs and solder ball defects from affecting chip performance and yield. In existing chip strip inspections, inspectors manually pull the chip strips under a microscope and manually adjust the position of the chip strips to meet observation needs. This method is prone to cause artificial damage to the chip, increasing the defective rate of the chip strips. In addition, the positioning accuracy of manually adjusting the position of the chip strips is low, and the efficiency of sampling is low.

[0003] For example, the chip strip detection device provided by patent CN213364621U uses electromagnetic force to pick up the ferromagnetic tray containing the chip strip to be detected on the conveyor belt at one end of the rotating electromagnetic pick-up cantilever, and uses electromagnetic force to pick up the ferromagnetic tray containing the detected chip strip on the positioning mechanism at the other end of the rotating electromagnetic pick-up cantilever. The rotating electromagnetic pick-up cantilever rotates and transposes to exchange the positions of the two. However, the above patent loads chips through the strip ferromagnetic tray, but cannot detect the size of the ferromagnetic tray and whether it is flat, and still has certain safety hazards.

[0033] The specific working method is that the first driving wheel 13 and the second driving wheel 14 rotate to drive the track 11 to rotate, driving the conveyor disc assembly 2 to move, and the external placement assembly places the chip tray 5 embedded with the chip on the tray seat 22 in sequence. According to the size and specifications of the tray, the distance between the image amplifier 36 and the tray is adjusted so that the camera 31 can clearly capture the chip in the tray, thereby ensuring that the flatness of the chip can be detected. When the chip tray 5 moves to the detection disk assembly 41, the second cylinder 47 controls the second support 42 to descend, so that the distance sensor 65 is flush with the tray, and then the third cylinder 412 drives the rotating disk 411 to rotate, and adjusts the first side plate 61, the second side plate 62 and the third side plate 63 to move inward so that the distance sensor 65 reaches a predetermined distance from the edge of the tray, thereby measuring the length and width of the chip tray 5. After completion, the third cylinder 412 retracts, adjusts the first side plate 61, the second side plate 62 and the third side plate 63 to move outward, the second support 42 rises, and the track 11 rotates to rotate the next chip tray 5 to be tested to the bottom of the detection disk assembly 41, and repeats the above steps.
