A Guide to High-reliability PCBs from Design to Specification
07/24/2019 |
Jeff Beauchamp, NCAB Group
Creating reliable PCBs is an outcome of considering all aspects that can affect reliability as early as possible in the design process. The further down the design process, the more expensive and risky it can be to fix. As they say, everything starts with the design. Because a good board design improves the reliability of the end product and lessens the risk of failure.
Microvias: Links of Faith are Not Created Equally
07/18/2019 |
Jerry Magera and J.R. Strickland, Motorola Solutions Inc.
Microvias connect adjacent copper layers to complete electrical paths. There are copper-filled microvias, which can be stacked to form connections beyond adjacent copper layers, and staggered microvias, which stitch adjacent copper layers with paths that meander on the layers between the microvias. This article discusses the various laser-drilled microvias and presents SEM photographs to begin the search for the root cause of weak copper interface.
Technically Appropriate Material Choices Are Key to Success

Nolan Johnson, I-Connect007
Materials are no longer a passive part of the design; they play an active role in the manufacturability, reliability, and speed of a PCB. Editor Nolan Johnson and Mike Creeden, founder of San Diego PCB Design, discuss several key characteristics that designers should consider in their material selection process.
