Just How Constant Is the Dielectric Constant of PCB Materials?
One of the crucial material factors that we address in our classes is the dielectric constant or relative dielectric constant, e r. This is sometimes called Dk by laminate suppliers. Sometimes, product developers are not clear as to the role the dielectric constant of PCB materials plays in a design, how to measure it, how to account for it, how it varies with frequency, and how to know if the dielectric constant data provided by the laminate

Temperature Sensors: Positive Temperature Coefficient (PTC) Thermistors
This is part 3 of our project to test every type of temperature sensor with all the standard implementations/topologies. If you want to add a temperature sensor to your project, this series has you covered with all the options covering the full range of precision and cost. At the end of the series we’ll be building a pair of host boards for all the sensor cards we have developed which will allow us to test, compare and contrast the different

PFC Circuit Design and Layout for Power Systems
Much as we would like, the power input into a PCB is not always a clean DC or sinusoidal signal. DC coming from a rectifier will have some ripple from the output capacitor, and AC signals can contain noise or be less-than-perfect sine waves. There are some ways to correct these problems, either by choosing the right filtration circuit or by shaping the input wave to produce maximum power output to a load in the system. If you’re working with an
