In a High Speed or High Frequency setting, circuit performance is dependent upon several characteristics and variables. Items such as the spacing between a forward signal and its return path, the trace width, trace thickness, trace length and numerous other variables all help to determine circuit performance. How much each of these variables enters into circuit performance is greatly affected by the characteristics of the base material upon which the circuit is placed. This course will discuss various base materials commonly used in High Speed Digital and High Frequency Analog circuits, as well as the variables affecting performance, such as Loss Tangent, copper type, etc. Additionally, the overall advantages and disadvantages of each material will be detailed. |
