Abstract

A present testing system (100) for testing electronic products is provided. The testing system includes a processor (10), a preliminary testing apparatus (20), and a final testing apparatus (30). The processor includes an encoding module (15) for generating product codes corresponding to the respective electronic products. The preliminary testing apparatus includes a data acquisition device (22) and a marking device (26). The data acquisition device tests the electronic products, acquires preliminary test data of the electronic products, and transmits the preliminary test data to the processor. The marking device marks the product codes onto the corresponding electronic products. The final testing apparatus includes a read device (32) for reading the product codes marked onto the electronic products and transmitting the product codes to the processor. The processor locates the corresponding preliminary testing data of the electronic products according to the product codes transmitted by the read device.
