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 […]
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 […]
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 […]
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 […]
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 […]
Freedom CAD has teamed with Valydate to offer Schematic Integrity Analysis. We are finding that schematic designs are becoming too complex to be completely manually/visually verified and errors introduced during schematic design can result in product failures or marginalities in production. Valydate can save hundreds of hours of visual inspection by verifying the schematics integrity […]
Freedom CAD is pleased to announce the ability to perform Power Integrity and IR Drop analysis to its array of services. As supply voltages continue to decrease and transistor count follows Moore’s law, Power Integrity has become an important consideration for any electronic package or PCB design. Using simulation to identify potential power integrity problems […]
This guide covers the six most common technical mistakes and problems encountered during PCB production and their soulution.
