Eutectic device and transistor packaging eutectic system

Abstract

The invention provides a eutectic device and a transistor packaging eutectic system. The eutectic device comprises a wafer suction structure, a to-be-eutectic product suction structure, preheating structures, eutectic heating platforms and eutectic recognition structures, the wafer suction structure is used for sucking wafers, the to-be-eutectic product suction structure is used for sucking to-be-eutectic products, the preheating structures are used for preheating the to-be-eutectic products, the eutectic heating platforms are used for heating a wafer and the to-be-eutectic products, the eutectic recognition structures are used for photographing in the eutectic process, the number of the preheating structures, the number of the eutectic heating platforms and the number of the eutectic recognition structures are all two, the two preheating structures are arranged corresponding to the two eutectic heating platforms respectively, and the two eutectic recognition structures are correspondingly arranged above the two eutectic heating platforms. According to the eutectic device, the eutectic efficiency can be improved, the structures of the two preheating structures are the same, the influence of machining and assembly tolerance of the preheating structures is greatly reduced, and the eutectic precision and the eutectic effect of the two eutectic heating platforms are basically consistent.

Description

technical field [0001] The invention belongs to the technical field of transistor packaging, and more specifically relates to a eutectic device and a transistor packaging eutectic system. Background technique [0002] The TO-CAN eutectic system currently used in the optical communication industry uses a heating platform, and the same preheating system is equipped with two or four preheating rotating tubes. Due to the large processing and assembly tolerances of each preheating rotary tube, the eutectic precision and eutectic welding effect between the preheating tubes will be greatly different, which will increase the difficulty of subsequent processes and affect product performance. [0003] The four preheating tubes of the existing TO-CAN eutectic system are distributed on the same rotating system at intervals of 90°, and are assembled on the rotating system by sinking the preheating tubes and fixing the top wire on the side. The suction nozzle puts the product into 1 # T...
