Current IssueLevel Up Your Design Skills
This month, our contributors discuss the PCB design classes available at IPC APEX EXPO 2024. As they explain, these courses cover everything from the basics of design through avoiding over-constraining high-speed boards, and so much more!
Opportunities and Challenges
In this issue, our expert contributors discuss the many opportunities and challenges in the PCB design community, and what can be done to grow the numbers of PCB designers—and design instructors.
Embedded Design Techniques
Our expert contributors provide the knowledge this month that designers need to be aware of to make intelligent, educated decisions about embedded design. Many design and manufacturing hurdles can trip up designers who are new to this technology.

IPC APEX EXPO: Hofer Discusses the Pros and Cons of Backdrilling
March 22, 2016 | Real Time with...IPCEstimated reading time: Less than a minute
General Manager James Hofer of Accurate Circuit Engineering discusses the process of backdrilling vias, including the benefits and drawbacks. Backdrilling can improve signal integrity, but it can create stubs that may act as unwanted antennas.

The Pulse: Drilling Down on Documentation
04/18/2024 | Martyn Gaudion -- Column: The PulseHow did a product aimed at signal integrity end up being more about documentation? For a little backstory, the Polar team has an unspoken “no business speak” rule at certain times. So, why is this column titled “Drilling Down?” I find it fascinating when a company sets off in one direction, but customers steer it in another. That’s what has happened here as customers took a product down a fork in the road we couldn’t predict. Your destination isn’t always where you initially set off to go, and that’s how we got to our subject of drills and drill documentation.

Reassessing Surface Finish Performance for Next-gen Technology, Part 2
03/04/2024 | Frank Xu, PhD and Martin Bunce of MacDermid Alpha, and John Coonrod of Rogers Corp.The introduction of 5G/6G has created a growing demand for faster rates of data transfer and operation at higher frequencies, pushing signals to travel toward the outer edges of conductors. As a result, the surface finish applied over the copper circuitry is now gaining more attention.
Beyond Design: Embedded Capacitance Material
02/22/2024 | Barry Olney -- Column: Beyond DesignEmbedding components into the multilayer PCB substrate can have many benefits, including reduced board size and improved signal integrity. However, embedded capacitance material (which is not really a component but rather part of the substrate) can improve power integrity dramatically by reducing AC impedance and generally enhancing the performance of the product. It takes up no additional space, is easy to implement (because it is compatible with standard FR-4 processes), and can be cost-effective.
