Problems solved by technology

[0003] At present, most chip sintering methods use the suction nozzle to absorb the chip and heat sink in the material box, and directly attach the chip to the heat sink in the solder area for sintering. This process does not consider the speed and height of the suction nozzle. , causing the nozzle to collide with the chip and the heat sink during the high-speed pressing process, and the position of the chip shifts during the welding process, thereby reducing the chip sintering accuracy

Abstract

The invention provides a chip sintering method and device, electronic equipment and a readable storage medium. The method comprises the steps of: calculating a first position coordinate of a heat sinkand a second position coordinate of a chip so as to control a first suction nozzle to suck the heat sink according to the first position coordinate and control a second suction nozzle to suck the chip according to the second position coordinate, calculating a first rotation angle of the heat sink sucked by the first suction nozzle and a second rotation angle of the chip sucked by the second suction nozzle; correcting the first position coordinate of the heat sink and correcting the second position coordinate of the chip; and according to a corrected third position coordinate of the chip and acorrected fourth position coordinate of the heat sink, placing the heat sink on a heating table, and placing the chip on the heat sink so as to sinter the placed chip. Collision and deviation generated in the positioning process and displacement of the chip position in the welding process can be avoided, and the sintering precision is improved.

Description

technical field [0001] The present application relates to the technical field of semiconductors, in particular to a chip sintering method, device, electronic equipment and readable storage medium. Background technique [0002] At present, due to the high cost of chip production, the effect of chip sintering directly affects the pass rate of chip production in the process of chip sintering, so low-cost and high-precision sintering methods are particularly important. [0003] Most of the current chip sintering methods use the suction nozzle to absorb the chip and heat sink in the material box, and directly attach the chip to the heat sink in the solder area for sintering. This process does not consider the speed and height of the suction nozzle. , causing the nozzle to collide with the chip and the heat sink during the high-speed pressing process, and the position of the chip shifts during the welding process, thereby reducing the chip sintering accuracy.
