If you are using plated through holes (PTH) in thick backplane/midplanes and printed circuit boards (PCBs) with a high layer count, they might be distorting the high speed, and high frequency digital signals passing through them. Depending on the stub length of the PTH, the distortion may be s...
Introduction Most reputable, customer oriented printed circuit board (PCB) manufacturers prefer to use microvias when building cost-effective products for their customers. High-density, multi-layer PCBs use microvias, as they represent the most affordable yet...

Why Edge Plate? A plated through hole(PTH) is a common feature in multilayered printed circuit boards. Fabricators drill holes through the stack and electroplate the walls with a layer of copper connecting two pads, one on the topmost layer and the other on t...
Introduction to Ceramics Ceramics have been the traditional material not only for electrical applications for the past 100 years, but have also been especially useful for highly reliable electronic applications. For instance, in the 19th century, ceramics...
Stackup in the design of a multilayer Printed Circuit Board (PCB) is an important factor from the point of view of the Electro-Magnetic Compatibility (EMC) of the product in which the PCB is used. Much of the radiation from the PCB can be reduced with a good stackup, whereas a poor stackup can...
