PCB Via Size and Pad Size Guidelines

There are some aspects of PCB design and layout that seem deceptively simple, and yet they have a complex answer that is related to many important aspects of manufacturing. One of these design aspects is the match between PCB via size and pad size. Obviously, these two points are related; all vias have a landing pad that supports the via and provides a place to route traces into a via pad. However, there are some important sizing guidelines to follow when the matching pad and via sizes, and this match is an important element of DFM and reliability.

Transmission lines (coplanar)

The boards use transmission lines to carry high-frequency signals. In addition to microstrip lines, coplanar transmission lines with a ground reference polygon are often found on boards. Coplanar transmission lines propagate the same wave type as microstrip transmission lines, but the electromagnetic field is more concentrated near the conductor, so coplanar lines have lower losses at high frequencies, less dispersion, and less interference to adjacent circuits.

When to Use Tented Vias in Your PCB Layout

There are some guidelines I see many designers implement as a standard practice, often without thinking about it. Some of these practices are misunderstood or implemented without best practices. Others are implemented without thinking about the potential problems. One of these is the use of tented vias, which is sometimes implemented in a PCB layout by default. Is this always the right practice?

How to Impedance Match and Terminate Capacitive Loads

The idea of a purely capacitive load is something of a fallacy. Yes, capacitors exist, but all capacitors are non-ideal, and it is this deviation from a theoretical capacitance that determines how to impedance match a load that exhibits capacitive behavior. Let’s take a look at this important aspect of interconnect design and see what it really means to terminate a capacitive load.
