A staff member at a PCB manufacturer once explained to me that they thought we were having an issue with a package warping. Unfortunately, component warping can occur both in a PCB and in components. In this article, we'll give an overview of warpage in a PCB, specifically in the circuit board and in the components.
If you're designing a wireless IoT device, and you know how to calculate the link budget, you can reasonably estimate whether your signal will reach its destination and be read by the receiver. To calculate the link budget, the designer needs to know something about all other sources of gain and loss in the system. Once link budget is determined, the designer can judge whether some modification is needed in their RF signal chain.
SMD components require precisely sized pads for soldering during assembly. The designer is responsible for ensuring pad sizes are correct, either by calculating them and comparing with footprint data, looking through datasheets, or by memorizing SMD pad size standards. If you have a component and you don't have access to the footprint, and you decide to biuld the footprint yourself, what resources are available to ensure you have the correct pad size?
Before we get too deep into this article, I’ll give you the simple answer. You probably can’t fix warping in your PCB after it’s already been fabricated. You can prevent an unwarped board from becoming warped during assembly, but only as long as materials were selected properly and the board is put into reflow correctly. We’ll run over some of these points in this article, and I’ll examine some points that might help you recover a warped board.
The eye diagram is a useful measurement or simulation as part of channel compliance. The measurement shows many different factors that can affect signal behavior simultaneously, ultimately allowing for qualification of errors and losses in a channel. In this article, I’ll run over some of the fundamental measurements that you could manually extract from an eye diagram and how they reveal some strategies for improving channel designs.
To readers who have been working in the PCB industry for most of your career, you have probably seen a very diverse group of professionals with varied skill sets and backgrounds. Designers might get started as engineers or as technicians, and some designers learn how to create beautiful PCB layouts in university. No matter how you got into PCB design, there are some important skills to know that will take you a long way towards advancing your career.
When starting out with PCB design, it’s common to treat the process as simply ‘connecting the dots’: as long as connections are made, it’s not particularly important how these connections are made. Having reviewed quite a number of PCBs of other PCB design engineers over the last few years, there are common, unfortunately erroneous, occurrences between a lot of them. This article aims to illustrate the top five beginner PCB design mistakes and what we can do to avoid making them. Let’s get started!

Version control systems (VCS) have been around for a long time in the software world but can be surprisingly new to some folks in the electronics design industry. Version control tools are great for tracking and maintaining entire codebases without the old-school copying, pasting, zipping, and emailing steps many PCB designers use.
When it's time to release your project to your manufacturer, it's essential to ensure that all the necessary design aspects like assembly, BOM, and documentation are accurately and completely conveyed. Consistency is key to ensuring a successful release. Without clear release documentation, the designer faces increased risks of costly manufacturing response, time-consuming rework, or unintentional defects that can make it into the final product.
One of the most difficult and frustrating things to arise when traveling to a foreign country is the language barrier. Communicating a simple greeting can sometimes seem like a big hassle. The same thing is true for different CAD tools. When your tools aren’t speaking the same language, you’re going to run into problems. Bridge this gap by building out your component libraries with everything it takes to truly define a component, including 3D models that seamlessly propagate into the PCB editor and beyond.
Working with local libraries seems like a simple solution, but we often don’t take into account the added time spent maintaining libraries and sharing them between team members. There is no good way to avoid duplicate efforts with component creation and no standardization to ensure consistent naming. Worst of all, there is no way to identify the latest component revision, and library files can be easily corrupted or misplaced. This webinar showcases the advantages of component storage in Аltium 365 to resolve the issues of local libraries and component management.

This webinar will help you determine what part of your designs need differential pairs implementations and how to create such pairs with a given wave impedance in Altium Designer.
Being able to design a board in your ECAD environment doesn’t mean that it is manufacturable in real life. You have to make sure your CAD representation won’t have any problems in the real world by taking some precautions. For example, there are certain areas that need to be free of components and have specified clearances like your board edge. This webinar will help you get acquainted with the creation and modification of your board shape so that you can ensure manufacturability.
