Abstract：Design of control system for high-speed test handler using turntable, Briefly introduced a chip test the entire process flow , On the basis of it, the test handler using turntable uses Compact RIO as the core controller and uses the modular design method to establish the system structure model, The connection between the module and the controller is connected via a bus or I/O port. On the software architecture the design method of three-layer software architecture is used to design the test handler using turntable. Discussing the effect of the three-layer architecture consists of the main level, the test level and the driver level in test handler using turntable .The main level calls the test level, the test level calls the driver level, the driver level is the communication with the outside world of the hardware .In addition, designing the chip detection data stream. The results show that the test handler using turntable has high real - time performance, high speed and high efficiency.
