Current IssueAdvanced Packaging and Stackup Design
This month, our expert contributors discuss the impact of advanced packaging on stackup design—from SI and DFM challenges through the variety of material tradeoffs that designers must contend with in HDI and UHDI.
Rules of Thumb
This month, we delve into rules of thumb—which ones work, which ones should be avoided. Rules of thumb are everywhere, but there may be hundreds of rules of thumb for PCB design. How do we separate the wheat from the chaff, so to speak?
Partial HDI
Our expert contributors provide a complete, detailed view of partial HDI this month. Most experienced PCB designers can start using this approach right away, but you need to know these tips, tricks and techniques first.

Calculating PCB Complexity and First-pass Yields
12/03/2024 | Happy Holden, I-Connect007There are three things I know mathematically about PCB yields: Defects that produce low yields may be systemic and repeatable, while others may be random (but you can test for this); you can predict yields if you take the time to collect the data; and yields are such wonderful things, so we should write about them more.
PCB Layout Rules of Thumb for Consideration
11/25/2024 | Patrick Davis, Cadence Design SystemsJust because a “rule of thumb” is usually based on experience instead of precise facts doesn’t negate its value. For instance, when I told my kids that a good rule of thumb was not to back-talk to their mother, they discovered very quickly how accurate my advice was once they crossed that line. There are a lot of rules of thumb that we rely on daily, including those that apply to PCB design.
Process Yield Statistics and Distributions
11/25/2024 | Dr. Pat Valentine, UyemuraThe costs of poor quality include all expenses incurred for not making or providing a perfect product the first time, including scrap, rework, re-purchasing raw materials, labor, and inventory. Companies operating at a three-sigma quality level can spend about 25% of their annual sales remediating poor quality costs. Other estimates put the costs of poor quality in the range of 25–40%. Poor quality can destroy a company.
It’s Only Common Sense: You Need to Learn to Say ‘No’
11/18/2024 | Dan Beaulieu -- Column: It's Only Common SenseWhy is it so hard to say “no?” I am a people pleaser, so this is a problem I deal with all the time. Most of us like to say “yes,” and we like to help people, especially when they are offering a business deal that looks like a genuine opportunity. Business opportunities come from all directions, and it’s tempting to say “yes” to them all. However, saying “yes” to everything can dilute your focus, spread your resources too thin, and pull you away from your core goals. Learning to say “no” is not just a skill; it’s necessary for success. It’s only common sense.
