This invention relates to the field of semiconductor product testing technology and discloses a high and low temperature testing and conveying device for semiconductor products. The device includes a carrier on which a tray is placed. Several sets of lower pressure plates and upper pressure components are respectively installed on the carrier. The lower pressure plates and upper pressure components are drively connected and move in opposite directions. One set of lower pressure plates has a positive trapezoidal plate, and an inverted trapezoidal plate is also provided inside the testing chamber. The inverted trapezoidal plate cooperates with the positive trapezoidal plate to move the lower pressure plates downwards. By setting relatively movable lower pressure plates and pressure cylinders, the cooperation of the inverted and positive trapezoidal plates during carrier movement drives the automatic clamping of the tray. This forcibly corrects the unevenness of the tray top caused by long-term wear, ensuring that the tray top always remains level. This guarantees that the suction cup can accurately pick up semiconductor products from all positions within a fixed stroke, effectively avoiding missed tests due to partial tray sagging, and significantly improving the integrity and reliability of the test.

The utility model discloses a hydraulic floating scraping type suction head for water floating scum drag scraping collection, including the floating room casing, the both sides of floating room casing one end all are established with the propulsion groove, two propulsion grooves's inside all are fixedly installed with hydraulic propulsion subassembly, the inside rotation of floating room casing is connected with two symmetrical settings of rubbing crusher, the surface fixed mounting of floating room casing has fixed component, the utility model discloses a hydraulic floating scraping type suction head for water floating scum drag scraping collection, through setting up hydraulic propulsion subassembly and preventing resistance guide wheel, hydraulic side pusher clockwise rotation pushes the water flow and produces the right thrust, counterclockwise rotation produces the left thrust, in this way, the floating room casing is convenient for adjusting direction, and preventing resistance guide wheel plays the role of guiding transmission, adjusting torque, through the change liquid flow direction and enhances the power transmission efficiency, guarantees the suction head multi -angle stable suction water floating scum, avoids appearing floating scraping type suction head and cannot normally suck even and sinks into the bottom of the water phenomenon.

This application discloses a method for mounting magnetic components, relating to the field of semiconductor mounting. The method includes the following steps: Step 1, applying weak magnetism to the nozzle; Step 2, ensuring that the magnetic attraction force generated by the nozzle satisfies: the nozzle magnetic attraction force ≤ the weight of the magnetic component; simultaneously, ensuring that the resultant force of the magnetic attraction force generated by the nozzle and the vacuum adsorption force satisfies: nozzle magnetic attraction force + vacuum adsorption force ≥ the magnetic attraction force of external iron on the magnetic component + the weight of the magnetic component. This application provides a method for adjusting the magnitude of the nozzle's magnetic attraction force, enabling the nozzle's magnetic attraction force to counteract the magnetic attraction force of external iron on the magnetic component, while preventing the magnetic component from being prematurely attracted and displaced before the nozzle contacts it. Furthermore, it enhances the nozzle's control over the chip to ensure stable pick-up of the magnetic component during transfer.
