How to Involve Customers in PCB Product Development
If you’re a freelancer and you’ve led or managed a complex PCB design project, the need to involve your customer in the product development process may not be obvious. Your customer is probably a project manager at a bigger company, so they’ll be overseeing progress on the project and leading communication with you. If you work on a small team or as part of a large organization, involving customers in product development can be time-consuming

The Importance of PCB Documentation
When it comes to real estate, it’s all about location, location, location. When it comes to ensuring a PCB will be built as designed, the emphasis is on documentation, documentation, documentation. This article describes the documents that need to be provided by the board design group to the fabricator, assembler, and test organization. Included is the description of the different drawings needed along with files and notes. All of these documents

How Vias Can Affect Very High-speed Signals
In a variety of articles posted on Altium’s resource center as well as in several other technical articles, papers, and conference proceedings, the advantages of differential signaling and its ability to deliver very high data rates have been touted. But, as with many things in life, those things that are beneficial can also have a downside. Such is the case with today’s products that deliver 32 Gbps and above data rates and the vias that are

A Short Tour Through The PCB Design Process
In several previous articles, I have addressed the PCB design process in terms of the tools involved, the basics of electromagnetic behavior on transmission lines, signal integrity, power delivery design and numerous other PCB design-related topics. But, one of the most important basics is to have a good sense of the factors that are considered to have the fastest design flow. This info spans the buses and types of signals including operating

The Switching Behavior Of A Series-Terminated Transmission Line
Series-terminated lines and differential signals serve as the links in all CMOS devices. While I have written extensively on differential signaling, its operations and its benefits, I have not addressed the switching behavior of a series-terminated line. That is the purpose of this article. The Basics The salient points about a series-terminated transmission line include the following: In this type of transmission line, a series termination is
