How to Implement DDR4

DDR4 succeeded DDR3 as the next generation of synchronous DRAM (SDRAM) software. DDR4 offers several improvements over its predecessor, including faster download speed, higher DIMM capacities, enhanced data integrity and power efficiency, and overall improved performance. Compared with DDR3, the DDR4 PCB design consists of several physical changes. First, DDR4 has 288 pins as opposed… Read More »

Four Technical Issues to Avoid in PCB Design

Dark Blue PCB

When the necessary precautions are ignored, printed circuit board hardware design and manufacturing processes are prone to fail. Design oversights such as inaccurate measurements and insufficient clearances can lead to printed circuit board (PCB) problems that impact final product performance. Catastrophic failures may result from over-etching and errors in drilling, as well as quality concerns… Read More »

Why You Should Outsource Your PCB Hardware Design

Printed circuit boards (PCBs) are an integral part nearly every electronic device you see or use today. Though some may be small in size, they can be highly complex in design and packed with power.  Creating your PCB design in-house allows for greater control over the project, but it comes with several drawbacks, particularly if… Read More »

Why Use High Density Interconnect?

One of the fastest growing technologies in printed circuit board (PCB) design is high density interconnect (HDI). HDI boards allow for higher circuitry density than traditional circuit boards due to a more concentrated arrangement of smaller components, creating more concise pathways. Blind and/or buried vias are commonly used to optimize space in HDI boards, and… Read More »

Through Hole vs Surface Mount: Which Should You Use?

Nearly every modern electronic device contains at least one printed circuit board (PCB)—a piece of material, such as plastic or resin board, onto which is printed or deposited tracks of conductive soldering material to connect various electronic components such as resistors, integrated circuits, capacitors, transformers, and so on. After all the components have been attached… Read More »

Freedom CAD Celebrates 15 Year Anniversary

15th Anniversary

May 16, 2018 marks the 15th year Anniversary for Freedom CAD Services.   Freedom CAD was founded on this day by Lou and Lauren Primmer, pioneers in the PCB CAD industry. They launched Freedom CAD when Plexus decided to divest the Nashua, NH design center in 2003.   The Primmer’s formed Freedom CAD with 11 other ex-Plexus… Read More »

Altium’s Judy Warner Discusses the Challenges of EDA Tool Licensing with Freedom CAD’s Scott Miller & Scott McCurdy

EDA Tool Licensing can vary greatly between different tools, some offer subscription licenses while others offer perpetual (or both).  There can be many challenges when trying to juggle demand across multiple tools, Altium’s Judy Warner interviews Freedom CAD’s COO, Scott Miller, and Director of Sales and Marketing, Scott McCurdy, about how FCS acquires and uses… Read More »
