Embodiment Construction

[0016] see figure 1 As shown, the integrated circuit board-level automatic test system provided by the present invention includes a computer, a GPIB interface, a USB interface, an automatic sorter (HANDLER) and a test interface board. Wherein, the computer is connected to the GPIB interface and the USB interface, and the GPIB interface is connected to the automatic sorting machine (HANDLER). Both the automatic handler (HANDLER) and the USB interface are connected to a test interface board, and the test interface board is connected to a device under test (DUT for short).

[0017] In this integrated circuit board-level automatic test system, the computer used can be an ordinary PC or an MCU (microcontroller) with relatively high computing power. The used automatic sorter (HANDLER) is preferably EPSON NS-6040HANDLER. This is a mixed-signal automatic sorting machine with single-channel / dual-channel / multi-channel test mode, which can perform high-speed testing of integrated circu...

Description

technical field [0001] The invention relates to an integrated circuit testing system, in particular to a board-level automatic testing system for integrated circuit chips with a USB interface, which belongs to the technical field of integrated circuit testing. Background technique [0002] In the integrated circuit manufacturing process, testing is one of the key means to ensure the performance and quality of integrated circuits. In recent years, with the continuous increase of integrated circuit design scale, the continuous improvement of design methods, and the widespread adoption of high-density process technology, the integrated circuits produced today are small in size and powerful in function. It has also raised an unprecedented challenge - how can manufacturers test these integrated circuit chips efficiently and cheaply. [0003] At present, the method for testing integrated circuits is usually to use automatic test equipment (Automatic Test Equipment, ATE for short)...
