Introduction to Circuit Boards At virtually all times of the day, we are almost surrounded by technology, and most of it helps in making our daily routines easier. In fact, most of us would probably feel completely lost without our electronic devices. ...

Modern electronic modules demand increasingly high levels of density. The miniature sizes of most surface mount devices (SMDs) that have now reached unbelievably small dimensions are primarily fueling this demand. Other advancements such as improvements in packaging technology has led to fine-...

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...
