METHOD OF DESIGNING A PRINTED CIRCUIT BOARD, AND PACKAGE TEST DEVICE HAVING THE PRINTED CIRCUIT BOARD |
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.
