Description
technical field [0001] The invention relates to a testing and sorting machine for integrated circuit series products, in particular to a test unit device of a novel QFN integrated circuit testing and sorting machine. It is suitable for testing and sorting of QFN integrated circuit products for communication products with high requirements such as LCD and mobile phones. Background technique [0002] QFN integrated circuit testing and sorting machine is mainly a mechatronic equipment composed of many mechanical parts with pneumatic components, stepping motors, optical fiber sensors, etc., and its program control is written by PLC. It is mainly composed of six local units including feeding unit, rotating unit, flow channel unit, testing unit, shuttle unit and distributing unit. Different from the general traditional test sorter, the test sorter of QFN IC series products requires very high test accuracy, and electrical requirements are also an important part, so the price of th...
