PCB Layout Guide

The physical design of a printed circuit board, or “layout” as it is colloquially known, typically has a set pattern of steps that designers must use. And while some of these steps are narrowly focused on an individual layout, such as tool usage or each corporation’s design workflow, some basic global steps must be followed. Here we’ll detail those basic steps in an easy-to-follow PCB layout guide that can help those unfamiliar understand the circuit board design process better.


Industrial PCB Design Rules

Industrial circuit boards are typically used in applications that require high power levels to drive motors or other heavy-duty equipment. Because of these power requirements, the layout rules and constraints are different than what would be used to layout a low-power IoT device. Here we’ll look at some of the differences with this type of circuit board layout technology and what designers need to understand about industrial PCB design rules.


PCB Flow Chart: From Design to Assembly

Thankfully, most people do understand the importance of PCBs and their uses, but very few understand the design and manufacturing processes required to build them. To help, we have put together a PCB flow chart that describes the design and assembly processes and how the two interact with each other. For clarity, we have omitted the fabrication process—other than to note the procurement of raw PCB fabs; otherwise, the following should help to simplify the overall process.


BOM Inventory Management: Staying Up to Date to Stay Ahead

This component availability problem can be traced back to several reasons. In some cases, it is due to inadequate planning, while others are due to CAD library management issues that designers need to understand better. Here we will examine these potential problem areas and some good PCB design BOM inventory management practices.


How Chip Shortages Impact Supply Chain Resiliency

The chip shortage and the global supply chain problems are big news these days, but do you realize how much the chip shortages impact supply chain resiliency? When one semiconductor chip is unavailable, it affects the next chip in line like dominos. Similarly, this process continues until an entire row of semiconductors is knocked over. Let’s look at this problem, its results, and how original equipment manufacturers guard against these problems to protect the production of their valuable electronics.
