Eliminating Nuances in the PCB Manufacturing Processes with Amit Bahl of Sierra Circuits PCB What is a PCB designer's role in improvement of manufacturing processes and capabilities? Let’s talk about design WITH manufacturing with Amit Bahl, the director of sales and marketing at Sierra Circuits. Read Article SAP and mSAP: Risk Vs. Reward During the recent IPC APEX expo, there was a lot of discussion about SAP, or semi-additive PCB processes. As with any new technology in PCB manufacturing, there were people that are excited to jump right in with SAP and start designing with much finer feature sizes and work through the inevitable changes to the traditional thought process. Others are in a let’s wait and see mode and of course, there are a few skeptics of SAP as well. There were a Read Article Nucleo Shields Multi-Board Design Learn how easy it is to create multi-board projects in this practical project article. Mark Harris covers why you would break larger boards into sub assemblies, and connection options between sub assembly boards. Read Article Wireless Module Designs: EnviroSense WiFi Weather Station Multiboard Get started with surface mounted sub-assemblies in this hands-on wireless module designs project. Mark Harris demonstrates the advantages of multi-board assemblies when creating your own surface mount module. Read Article Transformer Theory Made Simple Transformers used for 50/60 Hz power conversion must be physically larger than those used in wall-warts. Read this article and you will understand why. Read Article What Would You Do With a 5 Day Chip Supply for PCBs? US companies are reduced to a 5 day chip supply due to demand pressures and a long-lasting shortage in semiconductors. Read Article PCB Design Interview Questions: A Guide for New Engineers Newer PCB designers: here’s what you’ll face during your first round of job interviews. Follow these tips if you want to make an impression. Read Article A Guide to Mode Conversion, Its Causes, and Solutions Differential pairs are most often discussed in terms of their impedance and length matching tolerance, both with the goal of ensuring proper termination at the receiver and suppression of common mode noise. 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 Read Article Differential Stripline Impedance Calculator Try our differential stripline impedance calculator, built based on Wadell’s equations. Read Article Differential Microstrip Impedance Calculator Learn more about using and interpreting results from a differential microstrip impedance calculator. Read Article 48:29 Preparing your files for Fabrication Release When you’re done creating a new board, it’s time to send your design data to the manufacturer. Before releasing your Watch Video PDN Impedance Simulation and Analysis in SPICE PDN simulations can be performed in SPICE if you know how to properly model parasitics and inductive effects in power integrity analysis. Read Article When Do PCB Power Plane Resonances Occur? Do you know when a power plane resonance occurs in the PDN on a circuit board? We’ll examine when this occurs and what causes it. Read Article Overview of PCB/PCBA Reliability Testing and Failure Analysis PCB reliability testing and failure analysis go together. Here’s what you need to know and how to get started. Read Article Getting Through a PCB DFM Check If you’re reading an Altium Blog, it’s probably safe to say that you’ve either designed or fabricated printed circuit boards. If you’re like me, sending a design to fab is a bittersweet experience. On the one hand, you’ll soon have your hands on the hardware you’ve been working hard to design. But on the other hand, you know the fabrication site is going to send a list of PCB DFM requests, and that’s never fun. In this article, we’ll discuss the Read Article SAP (Semi-Additive Process) PCB Design with Flexible Circuits Now, with the adoption of Semi-Additive Process (SAP), PCBs with much finer lines and spaces are possible on flexible materials for space and weight improvements. Tara Dunn will show some ways on how this can be leveraged as an additional advantage for a SAP PCB design. Read Article PCB Via Size and Pad Size Guidelines Do you know what PCB via size you should use in your PCB layout? We’ll look at a few simple ways to answer this question.
