How to Choose PCB Plating for Your Finished Board

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?

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.

Blog
A Guide to Mode Conversion, Its Causes, and Solutions

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

PCB Via Size and Pad Size Guidelines

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.

Transmission lines (coplanar)

The boards use transmission lines to carry high-frequency signals. In addition to microstrip lines, coplanar transmission lines with a ground reference polygon are often found on boards. Coplanar transmission lines propagate the same wave type as microstrip transmission lines, but the electromagnetic field is more concentrated near the conductor, so coplanar lines have lower losses at high frequencies, less dispersion, and less interference to adjacent circuits.

Migrating Data From Other Version Control Systems

The development of electronic devices always involves the release of many different types of files. And these files are not static - they change as the project progresses. When filling a project with data, a user creates new files, modifies outdated files that have become irrelevant. Managing project data is a separate task, especially for large developments where several participants with different specializations are involved in the process.

Quarter-Wave Transformer Design For Real and Reactive Loads

RF systems operate with specific impedance values across entire interconnects, including on PCBs. Not all RF components are packaged in integrated circuits with defined impedances, so impedance matching circuits and line sections are needed to ensure signal transmission between different sections of an interconnect. One of these impedance matching techniques is the quarter-wave impedance transformer, which can be implemented as a printed trace with specific impedance.

RF Signal Chain and Link Budget Basics

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.

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.
