Patent ID: 8547548

Claim:
A final defect inspection system, comprising: a host device having a database, which stores circuit layout diagrams of circuit boards; a support tool supporting one circuit board to be inspected; a microscope comprising an eye lens, at least one object lens, a support plate and a support frame, wherein the support plate is movable and supports the support tool, the eye lens and the at least one object lens are used to inspect inspection regions preset on the circuit board, and the eye lens and the at least one object lens are jointed with the support plate through the support frame; a bar code scanner electrically connected to the host device and scanning a bar code on the circuit board, wherein the host device selects data and one circuit layout diagram from the database corresponding to the bar code; a signal transceiver provided on the support tool and electrically connected to the host device; and an electromagnetic pen electrically connected to the signal transceiver, wherein the electromagnet pen makes a mark a scrap region where any defect is found through the microscope, the signal transceiver receives and transmits each position of the mark to the host device, and the host device calculates each coordinate of the scrap region based on a relative position between the original point and each position of the mark, and stores each coordinate of the scrap region in a shipment file.
