Fresh PCB Concepts: Dynamic Solder Mask Compensation in PCBs

Solder mask has traditionally been treated as a secondary design layer, generated automatically after routing, reviewed briefly, and rarely revisited. In contemporary PCB fabrication, that assumption no longer holds. As conductor geometries shrink and assembly temperatures rise, solder mask has become a significant factor that influences manufacturability, yield, and long-term reliability.

Fresh PCB Concepts: Cost Stability in a Period of Copper and Gold Volatility

Anyone who works with PCBs in any capacity right now can feel that copper and laminate prices are not stagnant, gold price is increasing even faster, and the impact shows up quickly on PCB quotations. For many design teams, this feels like a force outside their control. Raw materials go up, and the board cost goes with it. I want to highlight that many of these swings are manageable.

Fresh PCB Concepts: The Importance of Bare Board Testing for Reliability

Manufacturing a clean PCB that functions during initial testing is not the same as manufacturing a truly high-quality board. The distinction between a PCB that is “good enough” and one that is built for long-term reliability often comes down to what the board has been subjected to long before it reaches the assembly line. While IPC standards outline a baseline for required testing, many meaningful evaluations a PCB can undergo are optional, and therefore inconsistent across suppliers.

Fresh PCB Concepts: Choosing Via Types—A Practical Guide for PCB Engineers 

When you first learn PCB routing, vias look like plumbing: holes that let signals pass between layers. As designs become denser and products shrink, vias develop from simple interconnects into deliberate engineering choices. Selecting between through-hole, blind, buried, microvia, or advanced options like skip vias is a balancing act between electrical performance, manufacturability, cost, and long-term reliability. In HDI boards, via strategy is as consequential as the stackup, material selection, or component placement.

Fresh PCB Concepts: The Vital Role of Front-end Engineers

Front-end engineers are the gatekeepers of factories and a cornerstone of successful fabrication. They are highly valued professionals who could be considered the protectors of our field. They study the details of each PCB that comes into their factories. Many of the boards they work on have not been manufactured before. Others have not been manufactured with their factory’s tools. Since factory engineers are not often in the public eye, many people do not understand the wealth of knowledge they have. The guidance they can offer is invaluable to some PCB designs, therefore, I encourage you to develop a good relationship with the engineers at your favorite supplier.

Fresh PCB Concepts: The Pros and Cons of Gerber, ODB++, IPC-2581

Which file format should I use? This is something I am asked frequently, and it reminds me of when I was in college and working for a PCB fabricator. I’d work my way to the sales department so I could support them with design for manufacture (DFM) analysis—a daunting task while also trying to remember all the information I was learning in my engineering classes. However, an engineer with many years of experience was a wonderful mentor to me. He not only taught me a plethora of information about PCBs, but he also taught me about the many different file formats we use for PCBs. He even shared painful legends of screen projectors and making screens.

Fresh PCB Concepts: Designing Controlled Impedance PCBs

Imagine that you are getting ready to work on a new PCB when the electronics engineer you work with suddenly gives you a controlled impedance requirement for the board. This will be your first experience designing a PCB with controlled impedance traces. Where do you begin? I encourage you to seek out IPC-2141, Design Guide for High-Speed Controlled Impedance Circuit Boards, to help answer that question; in addition, this introduction may also help. Controlled impedance traces are necessary on some PCBs for high-speed signal transmission. The goal with controlled impedance traces is to design the proper propagation delay into the trace.

Fresh PCB Concepts: The Right Board for the Flex Job

We like to say we like the board that is best fit for the job, but what does the right board for your job specifically look like? In this article we will go over the benefits and design types of flexible PCBs. So, what is a flex PCB? A flex board is defined as a bendable board with one or more conductive layers. There are different types of flex boards to fit any situation you may have. IPC defines them in five types, all are different constructions. To put it shortly these constructions are as follows, One layer of flex, double sided, multilayer flex, multilayer rigid-flex, and double or multilayer flex without electrically connected layers.

Fresh PCB Concepts: What Damage Does the Assembly Process Have on a PCB? Part 4

In Part 3 of this series, I discussed how phenolic cured laminates can be mechanically weaker than their dicey cured laminate counterparts. I pointed out some of the material properties listed on material data sheets that explain and support this point. Whereas the phenolic systems are better at thermal management, the dicey systems are better under mechanical stress. There is no right or wrong here. The systems just perform differently under different circumstances. Understanding the differences and how they relate to the applied assembly process are important to ensure success. For this post I would like to discuss the effect moisture has on the printed circuit board.

Fresh PCB Concepts: Does the Assembly Process Damage a PCB? (Part 3—Phenolic Epoxy Systems)

In part 2 of this series, I explained how the T260 and T288 material datasheet values could be used as an indicator of how durable a laminate system (FR-4) shall be when exposed to heat. The higher the temperature applied, the less time it takes to delaminate the FR-4. Traditional dicey cured epoxy systems do not stand up to lead-free assembly temperatures as well as one would think. The phenolic cured epoxy systems are much better suited and able to withstand the higher temperatures applied with lead-free assembly temperatures for longer periods of time.

Fresh PCB Concepts: Recommendations for Track Welding and Open Circuit Repair

Track welding is what some factories may opt for if they find an open circuit. The technique is to attach/stick/weld a thin piece of copper across the broken track. Sounds okay, right? But how reliable is the repair? And how does IPC cover this subject? Well, IPC doesn’t have too much to add on this subject other than mentioning that the customer and supplier should agree whether repairs are acceptable or not. Therefore, if the customer does not advise it is not acceptable, then it is acceptable by default. In my experience, the issue is rarely discussed between the supplier and customer.
