分选机主要应用于芯片设计检验阶段和成品终测（FT）环节，是终测环节重要检测设备之一。

转塔式分选机尤其适用于小型片式半导体分立元件的打标、测试、分选和包装，是一种主转盘在中心，各个测试工位按照顺序均布在主电机周围的一种高速分选机，通常包含工位有16个和24个等多种型号。

• 产品通过上料结构被送到主电机转盘上;

• 主电机转盘吸住芯片并通过转动将产品送到下一个工位;

• 上料工位工作;

• 主电机转盘吸取新的一个产品。

Sorting machines are mainly used in the chip design inspection stage and the final product testing (FT) stage, and are one of the important testing equipment in the final testing stage.
The rotary tower sorting machine is particularly suitable for marking, testing, sorting, and packaging of small chip semiconductor discrete components. It is a high-speed sorting machine with a main turntable in the center and various testing stations arranged uniformly around the main motor in order. It usually includes multiple models such as 16 and 24 stations.
The product is delivered to the main motor turntable through the feeding structure;
The main motor turntable sucks the chip and rotates it to deliver the product to the next workstation;
Working at the loading station;
The main motor turntable draws a new product.
