6-Layer PCB Design Guidelines

Once you’ve run out of room on your 4-layer PCB, it’s time to graduate to a 6-layer board. The additional layer can give you room for more signals, an additional plane pair, or a mix of conductors. How you use these extra layers is less important than how you arrange them in the PCB stackup, as well as how you route on a 6-layer PCB. If you’ve never used a 6-layer board before, or you’ve had EMI troubles with this stackup that are difficult to solve, keep reading to see some 6-layer PCB design guidelines and best practices.

Component Management

Help Ensure The Best Designs With Component Management

There are many aspects to designing a PCB. One of the larger aspects has to do with managing your components. We all need components for our designs, but are those components in our library and designs up-to-date or even purchasable? These questions need to be answered before we can safely use them. If not, we could just be wasting our time designing with invalid components. Altium Designer® has several tools to help you manage the components in your libraries and designs.

Are Hybrid PCB Stackups Reliable?
Blog
How Reliable is Your Hybrid PCB Stackup?

PCB stackups often incorporate slightly dissimilar materials that could pose a reliability problem. Hybrid PCBs are one case where the PCB stackup will include different materials, typically a standard FR4 laminate and a PTFE laminate for RF PCBs. Designers who want to take the lead on material selection when designing their hybrid stackups should consider these factors that affect reliability. As with any PCB stackup, make sure you get your fabricator involved in the manufacturing process early to ensure reliability problems do not arise during production.

Monte Carlo Simulation vs. Sensitivity Analysis: What’s the Difference?

In a previous article about circuit simulation and reliability, I looked at how Monte Carlo analysis is commonly used to evaluate circuits that are subject to random variations in component values. Sensitivity analysis is a bit different and it tells you how the operating characteristics of your circuit change in a specific direction. Compared to a Monte Carlo simulation, sensitivity analysis gives you a convenient way to predict exactly how the operating characteristics will change if you were to deliberately increase or decrease the value of a component.

What's In Your BGA Land Pattern and Footprint

If you look in datasheets for most components, you’ll often find a recommended land pattern, usually alongside some mechanical package information and assembly information. This is not always the case with BGA components, especially components with high ball count. There are a few reasons for this that we can speculate: those ball counts might just be too big to put into a single page, or the manufacturer just expects you to know how to create that land pattern.

Meeting Standards: IPC 6012 Class 3 Annular Ring

Designers often conflate leftover annular ring and pad sizes - they need to place a sufficiently large pad size on the surface layer to ensure that the annular ring that is leftover during fabrication will be large enough. As long as the annular ring is sufficiently large, the drill hit will not be considered defective and the board will have passed inspection. In this article, I'll discuss the limits on IPC-6012 Class 3 annular rings as these are a standard fabrication requirement for high-reliability rigid PCBs.

Decoding PCB Fabrication Notes

Sending a board out for fabrication is an exciting and nerve-wracking moment. Why not just give your fabricator your design files and let them figure it out? There are a few reasons for this, but it means the responsibility comes back to you as the designer to produce manufacturing files and documentation for your PCB. It’s actually quite simple if you have the right design tools. We’ll look at how you can do this inside your PCB layout and how this will help you quickly generate data for your manufacturer.

Design Basics for HDI and the HDI PCB Manufacturing Process

As the world of technology has evolved, so has the need to pack more capabilities into smaller packages. PCBs designed using high-density interconnect techniques tend to be smaller as more components are packed in a smaller space. An HDI PCB uses blind, buried, and micro vias, vias in pads, and very thin traces to pack more components into a smaller area. We’ll show you the design basics for HDI and how Altium Designer® can help you create a powerful HDI PCB.

How to Design to a Differential Impedance Specification

The concept and implementation of differential impedance are both sometimes misunderstood. In addition, the design of a channel to reach a specific differential impedance is often done in a haphazard way. The very concept of differential impedance is something of a mathematical construct that doesn’t fully capture the behavior of each signal in a differential trace. Keep reading to see a bit more depth on how to design to a differential impedance spec and exactly what it means for your design.

How to Solve Your Engineering Design Review Challenges

You’ve possibly gone through plenty of engineering design reviews, both on the front-end of a project and the back-end before manufacturing. Engineering design reviews are performed to accomplish multiple objectives, and with many engineering teams taking a systems-based approach to design and production, electronics design teams will need to review much more than just a PCB layout and BOM. Today’s challenges with sourcing, manufacturability, reliability, and mechanical constraints are all areas that must be confronted in real designs

PCB Via Current-Carrying Capacity: How Hot is Too Hot?

One common question from designers is current-carrying capacity of conductors in a PCB. Trace and via current-carrying capacity are legitimate design points to focus on when designing a new board that will carry high current. The goal is to keep conductor temperatures below some appropriate limit, which then helps keep components on the board cool. Let’s dig into the current state of thermal demands on vias in PCBs and how they compare to internal and external PCB traces.

Best Practices in Hardware Version Control Systems

Any project can get very complex, and the PCB design team needs to track revisions throughout a project. Why worry about tracking revisions? In the event you ever receive changes to product functional requirements, major changes are made to your product’s architecture, or you’re ready to finalize the design and prepare for fabrication, it’s best to clone a project at its current state and begin working on a new version. Keeping track of all these design changes in a PCB design project takes the type of hardware version control tools you’ll find in Altium 365™.

Copper Pour and Via Stitching: Do You Need Them in a PCB Layout?

To pour or not to pour, to stitch or not to stitch… Over many years, some common “rules of thumb” have become very popular and, ultimately, taken a bit out of context. Rules of thumb are not always wrong, but taking PCB design recommendations out of context helps justify bad design practices, and it can even affect the producibility of your board. Like many aspects of a physical PCB layout, via stitching and copper pour can be like acid: quite useful if implemented properly, but also dangerous if used indiscriminately.

Should You Use Power MOSFETs in Series?

Power MOSFETs enable a huge range of electronic systems, specifically in situations where BJTs are not useful or efficient. MOSFETs can be used in high current systems in parallel arrangements, but what about their use in series? Both arrangements of MOSFETs have their pitfalls that designers should consider. Let’s look at MOSFETs in series as they are quite useful in certain systems, but be careful to design your circuits and your PCB for reliability.
