Win at Power Delivery System Design

Win at Power Delivery System Design This article is intended to define the new challenges and provide guidance in how to successfully engineer the Power Delivery System (PDS) so it meets the needs of new technologies. As integrated circuit technology has made it possible to put billions of transistors on a single IC it has resulted in very powerful systems on a chip. This has made it possible to put the equivalent of supercomputers inside video games, cell phones and a host of Read Article

Differential pairs

Confused About Differential Signaling or Clocks? Check out this quick snippet of the Altium Podcast with guru of high speed design Lee Ritchey The primary reason that differential signaling is dominating the digital world is that far higher data bandwidths can be achieved over a pair of wires than with parallel, single-ended signaling protocols. The Internet as we know it would not be possible without differential signaling. This information is intended to clear up any confusion about Read Article

Everything You Need for Successful PCB Stackup Design There are three demands placed on stackup design: controlled impedance, crosstalk control and the need for interplane capacitance. Some fabricators could get the impedance right in a stackup, but there is no way for them to account for the other two. This responsibility rests with the design engineer who is the only one who knows what is needed and how to implement the needed control. This information is intended to provide guidance on the Read Article

Noise Transfer is Annoying, Learn How to Contain Crosstalk

Noise Transfer is Annoying in PCBs, Learn How to Contain Crosstalk from expert Lee Ritchey The words crosstalk and coupling are used to describe the injection of electromagnetic energy from one transmission line to another running nearby. In printed circuit boards crosstalk is usually two traces running side by side in the same layer or one over the top of the other in adjacent layers. This coupled energy appears as noise on the victim trace and can cause malfunctions if the amplitude is too large. Learn how this noise is transferred Read Article

How to Control Switching Signals with Terminations for Best Signal Quality

How to Control Switching Signals with Terminations for Best Signal Quality A transmission line is a pair of conductors used to deliver energy in the form of an electromagnetic field. Most of us are familiar with the wires that lead to our houses to deliver the power needed to operate our lights and appliances. In the context of PCB design, it is a signal in a signal layer on top of a plane or between two planes. TRANSMISSION LINES AND TERMINATIONS The purpose of this section is to explain what transmission lines are Read Article

Sharp Tools to Get the Job Done Fast

Sharp Tools to Get the Job Done Fast “You cannot mandate productivity, you must provide the tools to let people become their best.” ― Steve Jobs That is some great advice, from a leader in the industry. I would expound on his thought, that it really doesn’t matter how qualified an individual is. They could have gone to the best schools got the best degrees possible. IF… they do not have the correct tools to do the job. The result is an absolute travesty for the company and for the Read Article

Building Your Treasure Trove of Component Information

Building Your Treasure Trove of Component Information Learn about PCB data Management and how it interrelates to the PCB Design process and roles of everyone involved. According to the business dictionary, a process is defined as: “A sequence of interdependent and linked procedures which, at every stage, consume one or more resources (employee time, energy, machines, money) to convert inputs (data, material, parts, etc.) into outputs. These outputs then serve as inputs for the next stage until a Read Article

Systems and Structures to Avoid the Sound of Deadlines Whooshing By

Systems and Structures to Avoid the Sound of Deadlines Whooshing By Adopt the SMART rules of PCB Data Management and avoid additional cost and/or lost design time. When we begin to look in more detail at how to do anything, it becomes a little problematic. The reason is that every organization varies in product, structure and management requirements. We can guarantee that there will not be a “single” answer or solution to the questions at hand. My intention therefore is not to prescribe a sole structure or Read Article

Drinking From the Firehose of PCB Data

Drinking From the Firehose of PCB Data There are several problems that are directly impacting the PCB Design area and specifically the PCB Data Management. For some time, it has not been business as usual, it is vital to understand these issues and develop a good strategy to handle them. With the invention of the internet, civilization dragged itself (sometimes kicking and screaming) out of the industrial age and into the “Information Age”, as an official description of the 21st Read Article

The Brave New World of PCB Data Management

A Brave New World: PCB Data Management and the Great Paradigm Shift PCB Data Management is the acquisition, storage, verification, usage, distribution and maintenance of all the data connected to the development of printed circuit boards or PCBs In what some refer to as the “Olden Days” of the Electronics industry, it was definitely a different time. There wasn’t much need for PCB Data, let alone anything to manage it with. Tasks such as creating schematics, BOMs, drawings, and gerber files were problematic at Read Article

Get to Know Microvia Manufacturing Processes and HDI Substrates

Get to Know Microvia Manufacturing Processes and HDI Substrates Initial HDI Fabrication High Density Interconnect printed circuits actually started in 1980, when researchers started investigating ways to reduce the size of vias. The first innovator is not known, but some of the earliest pioneers include Larry Burgess of MicroPak Laboratories (developer of LaserVia), Dr. Charles Bauer at Tektronix (who produced photodielectric vias), [1] and Dr. Walter Schmidt at Contraves (who developed plasma-etched vias) Read Article

Introduction to High Density Interconnects and the Evolution of Electronics

Introduction to High Density Interconnects and the Evolution of Electronics The Evolution of Electronics Electronics is a relatively new industry, since it has been only 65 years since the transistor was invented. The radio tube was developed nearly 100 years ago but blossomed in WWII, with communications, radar, ammunition fusing (especially the radar-altimeter electronic fusing for the first atom bomb) and has evolved into the world largest industry. All electronic components must be interconnected and assembled to Read Article

Layer Management as a Design Tool Priority

Layer Management as a Circuit Board Design Tool Priority Rome wasn’t built in a day, and the same could be said for printed circuit boards. PCBs are similar to cities in that they contain pathways connecting components. Components have dimension into the surrounding air space, as well as into the thickness of the board itself. Hidden subsystems similar to underground wiring and cityscape piping reside within the thickness of the boards. Printed circuit boards mimic cities with their layers of Read Article

Design Rules to Fanout a Large BGA

Design Rules for Large BGA Fanout I have known people during my career who insisted on hand-routing every PCB design that they worked on. They would say that their manual routing performed better, looked better, and was just better in general. I’m not going to argue one way or the other on that, but I will say that there is one thing that can not be argued with; all of that manual routing took them a much longer time to complete than if they had used automated routers. With today Read Article
