Design simulator using Impedance test method for the signal fidelity in PCB Tracks

摘要

PURPOSE: A design simulator using an impedance calculation method for signal fidelity in a printed circuit board track is provided to develop a control impedance calculation tool, thereby easily performing experience or a passive impedance calculation method. CONSTITUTION: When a profile of a coupon class is selected by a user, circuit width of a printed circuit board(PCB) and an insulation layer interval are adjusted and a coupon is manufactured(S1, S2). Properties of a process are found by repetitively performing a test and measurement and control impedance of the PCB is calculated(S3). The test is repeated by changing values of track width and track thickness in the PCB and work, which finds process variables suitable for requirements of a designer, is repeated, designed and stored(S4).
