    摘要: In a method of designing a printed circuit board, a package capacitance, a package inductance, and a chip capacitance of an actual memory device are calculated. A signal line capacitance and a signal line inductance per unit length of a signal line are calculated based on characteristics of the printed circuit board. A length of the signal line for each pin is determined based on the package capacitance and the signal line capacitance.

    摘要: In a method of testing an object, a first test pattern for testing a first device in the object may be set in a tester. A second test pattern for testing a second device in the object may be set in a test head electrically connected between the tester and the object. The first test pattern may be provided to the first device through the test head and the second test pattern may be provided to the second device by the test head to simultaneously test the first device and the second device. Thus, the first device and the second device different from each other may be simultaneously tested without changing test conditions in the tester, so that a time for testing the object may be reduced.

    摘要: A printed circuit board (PCB) including an impedance-matched strip transmission line includes a strip transmission line including a main line and at least one pair of branch lines branching off from the main line. An upper ground layer is disposed over the strip transmission line and has upper opening parts corresponding in position to the branch lines. A lower ground layer is disposed under the strip transmission line and has lower opening parts corresponding in position to the branch lines. The upper and lower opening parts are symmetric about the branch lines of the strip transmission line.
