Method for processing tray clamp

Abstract

The invention provides a method for processing a tray clamp, and belongs to the field of tray clamps. The method for processing the tray clamp includes the following steps that all layer boards are holed, so that a plurality of containing holes are formed in the corresponding layer boards; all the layer boards are stacked, the containing holes between every two adjacent layer boards are made to communicate with one another, and an initial tray can be formed after all the layer boards are stacked; high-temperature resistance powder is pressed into the containing holes of the initial tray; the initial tray is subjected to vacuum diffusion welding; and the high-temperature resistance powder in the containing holes is taken out. In the welding process, due to the fact that the containing holesin the tray are filled with the high-temperature resistance powder, the high-temperature resistance powder can play the effect of heat transfer, the temperatures of all the positions of the tray canbe made basically consistent, and therefore the temperature difference of the center and the edge of the tray is reduced and heat stresses generated in the temperature rising process of the tray are effectively lowered. Meanwhile, the high-temperature resistance powder can effectively change the thermal field state of the layer boards in the postwelding cooling process and the thermal stresses caused by uneven cooling of the layer boards can be effectively avoided.

Description

technical field [0001] The invention relates to the field of pallet clamps, in particular to a processing method for pallet clamps. Background technique [0002] The semiconductor chip microelectronics industry is at a highly automated level, and the automated production line needs to be equipped with high-precision pallet fixtures to position and fix semiconductor chips. This type of fixture requires high precision, and the thickness is generally less than 5mm, so high-precision fixtures cannot be obtained by means of transmission sheet metal machining. [0003] At present, the method of manufacturing pallet fixtures on the production line is: divide the pallet fixture into several layers, and process holes for each layer, and then assemble each layer by spot welding and deliver them for production. With this processing method, only the edge of the pallet fixture is heated, and there will be a temperature difference between the middle position and the edge position of the ...

AI Technical Summary

Problems solved by technology

This processing method makes only the edge of the pallet fixture heated, and there will be a temperature difference between the middle position and the edge position of the pallet fixture. The thermal stress between the middle position and the edge position of the pallet fixture is different, and the pallet fixture is easily scrapped due to deformation.
