Best Methods for Calculating SMD Pad Size in PCB Design

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?

Can You Fix a Warped PCB?

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.

Beginner PCB Design Mistakes and How To Avoid Them

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!

How to Select Copper Foil for High-Frequency PCB Design

The PCB materials industry has spent significant amounts of time developing materials that provide lowest possible signal loss for products with RF applications. For high speed and high frequency designs, losses will limit signal propagation distance and distort signals, and it will create an impedance deviation that can be seen in TDR measurements. In this article, we'll look at the balance between copper foil losses and other types of losses in a PCB, as well as some strategies that are commonly used to overcome roughness.

PCB Trace and Pad Clearance: Low vs. High Voltage

High voltage/high current designs carry safety requirements which need to be met by designers. Similarly, high speed designs need to have suppressed crosstalk in order to ensure signal integrity. The key design aspects that relate to both areas are your PCB trace clearance and pad clearance values. These design choices are critical for balancing safety, noise suppression, and manufacturability.

How to Maximize Copper in Your PCB Design: The Pros and Cons of Copper Pouring Versus Placing

There is a saying in copper pour PCB design, “Copper is free.” It means a PCB editor designer must think in reverse. A board starts off as solid copper, and the copper you don’t want is removed. It is faster to build, less consumptive, and less expensive to make a board that is mostly copper as compared to the same size board that is mostly bare. Picking the correct technique will make the difference between an effortless or frustrating experience.
