Reliability testing and failure analysis of a PCB/PCBA go hand-in-hand; when designs are stressed to the limit, their failure modes need to be determined through thorough inspection and analysis. To get started on this topic, it’s important to understand the qualification aspects that will govern your bare board design and the PCBA. We’ll look at the various dimensions of PCB/PCBA reliability, as well as some of the standard failure analysis techniques used to identify potential design change requirements.

By now, designers should be aware of some important behavior involved in power delivery to components in a PCB, particularly for digital components. All digital components produce and manipulate wideband signals, where the frequency content theoretically extends up to infinite frequency. As such, some radiation may propagate through your PCB, leading to resonant behavior that is not observed on the power rail.

Supply shortages have become and continue to be a common problem, especially when it comes to the world of electronics. It's hard to get all the different components for our boards. Heck! It's even tough to get the board themselves too! When electronic components become obsolete or out of stock, design and production can suffer lengthy delays. With current supply chain delays and with an average of 15 end-of-life notices issued every day, obtaining the parts you need is a challenge.
![Selecting a plating material](/s3/files/styles/video_homepage_teaser/public/2022-02/%D0%B8%D0%B7%D0%BE%D0%B1%D1%80%D0%B0%D0%B6%D0%B5%D0%BD%D0%B8%D0%B5_2022-02-01_155909.png?itok=e-D1LijT)
Once your board passes through the standard PCB fabrication process, the bare copper in your PCB will be ready for the application of a surface finish. PCB plating is applied to protect any copper in your PCB that would be exposed through the solder mask, whether it’s a pad, via, or other conductive element. In this article, I’ll run over the different PCB plating material options and their advantages in your PCB.
![What is the PCB Supply Chain?](/s3/files/styles/video_homepage_teaser/public/2022-01/%D0%B8%D0%B7%D0%BE%D0%B1%D1%80%D0%B0%D0%B6%D0%B5%D0%BD%D0%B8%D0%B5_2022-01-25_155537.png?itok=wOAY7_E1)
The PCB supply chain encompasses multiple components, raw materials, and the PCB itself. PCBs and PCB assemblies are often the most technically complex components that are purchased for electronic assemblies and products. The complexity of modern PCBs leads to several challenges for a supply chain management team that may be significantly different when compared with other commodities the team manages. In this brief guide, we'll look in-depth at the PCB supply chain, and specifically what falls within the purview of a procurement and supply chain management team.
![What is mode conversion](/s3/files/styles/video_homepage_teaser/public/2022-01/%D0%B8%D0%B7%D0%BE%D0%B1%D1%80%D0%B0%D0%B6%D0%B5%D0%BD%D0%B8%D0%B5_2022-01-25_155359.png?itok=UgNmpbB_)
On interconnects, such as board-to-board connections or cascaded transmission line arrangements, you have an important EMC compliance metric that is sometimes overlooked. This is mode conversion, which can be visualized in an S-parameter measurement for differential and common-mode signal transmission. In this article, we’ll look at a short overview of mode conversion in high-speed design with some examples from common differential standards.
![Pad and via sizing](/s3/files/styles/video_homepage_teaser/public/2022-01/%D0%B8%D0%B7%D0%BE%D0%B1%D1%80%D0%B0%D0%B6%D0%B5%D0%BD%D0%B8%D0%B5_2022-01-21_121615.png?itok=OvO_gW6l)
There are some aspects of PCB design and layout that seem deceptively simple, and yet they have a complex answer that is related to many important aspects of manufacturing. One of these design aspects is the match between PCB via size and pad size. Obviously, these two points are related; all vias have a landing pad that supports the via and provides a place to route traces into a via pad. However, there are some important sizing guidelines to follow when the matching pad and via sizes, and this match is an important element of DFM and reliability.
![Preparing your files for Fabrication Release](/s3/files/styles/video_homepage_teaser/public/2022-01/%D0%B8%D0%B7%D0%BE%D0%B1%D1%80%D0%B0%D0%B6%D0%B5%D0%BD%D0%B8%D0%B5_2022-01-19_152910.png?itok=BYD3mtqD)
When you’re done creating a new board, it’s time to send your design data to the manufacturer. Before releasing your designs, you’ll want to make sure that everything is ready and works as intended.
