Your Complete Guide to Circuit Board Thermal Analysis

Your Complete Guide to PCB Thermal Analysis The physical properties of your PCB substrate and copper conductors are the main factors determining how a circuit board will heat up during operation. Circuit board thermal analysis techniques aim to predict when and where a board will heat up during operation, as well as how hot the board will get. This important part of the analysis is geared to ensure component-level and board-level reliability, and it can influence many design decisions Read Article

50 Ohm impedance

The Mysterious 50 Ohm Impedance: Where It Came From and Why We Use It 50 Ohm impedance became the standard impedance used in RF transmission lines long ago, but it is still useful today and is a standard reference impedance used in test equipment. Read Article

S-parameter measurement

S-Parameter Measurements and Errors in Power Integrity No matter where you look, it seems S-parameters never go away! They are mandatory tools for understanding some systems, such as an interconnect or antenna, while other network parameters can sometimes give a better conceptual understanding of electrical behavior. These parameters are normally reserved for signal integrity among electronics engineers, but if you look hard enough, you’ll find that S-parameters are also used for power integrity Read Article

The Benefits of High-Dk PCB Materials

The Benefits of High-Dk PCB Materials The terms “high-speed design” and “low-Dk PCB laminate” are often used in the same articles, and often in the same sentence. Low-Dk PCB materials have their place in high speed and high-frequency PCBs, but high-Dk PCB materials provide power integrity. Low-Dk PCBs are typically chosen as they tend to have lower loss tangent. Thus high-DK PCB materials tend to get overlooked for high speed and high-frequency PCBs. When we look at power integrity Read Article
