Current IssueShowing Some Constraint
A strong design constraint strategy carefully balances a wide range of electrical and manufacturing trade-offs. This month, we explore the key requirements, common challenges, and best practices behind building an effective constraint strategy.
All About That Route
Most designers favor manual routing, but today's interactive autorouters may be changing designers' minds by allowing users more direct control. In this issue, our expert contributors discuss a variety of manual and autorouting strategies.
Creating the Ideal Data Package
Why is it so difficult to create the ideal data package? Many of these simple errors can be alleviated by paying attention to detail—and knowing what issues to look out for. So, this month, our experts weigh in on the best practices for creating the ideal design data package for your design.

Bowman Technical Team Appoints Principal Engineer
December 20, 2021 | BowmanEstimated reading time: Less than a minute

Bowman, a US manufacturer of XRF quality control instruments, has announced a principal addition to its headquarters organization.
Xin Jiang joined the company as Principal Electrical/Firmware Engineer. He holds an MSE (Master of Science, Electrical Engineering) and has 30+ years of experience in digital circuits, embedded software, and product design. He has an impressive record with UL, CE, and FDA compliance and testing, and will lead Bowman’s effort in designing electronics for automated XRF tools and next-generation instruments.
In his previous posts, he specialized in HPLC chromatography and X-ray technology for medical device applications, and was a consulting test engineer for Teradyne, a semiconductor test equipment provider.
His responsibilities at Bowman cover firmware, product design, and regulatory compliance; he reports to Engineering Manager, Robert Magyar.
Bowman is a leading manufacturer of precision XRF plating measurement systems, providing equipment evaluation, selection, commissioning, maintenance and quality systems modernization throughout North America, South America, and Eurasia.

Setting Design Constraints Effectively
07/31/2025 | Stephen V. Chavez, Siemens EDAPCB design requires controlling energy within the medium of a PCB. The manner in which we control the chaos of energy is by implementing and utilizing physical and electrical rules, known as constraints, along with a specific structure and material(s) that make up what is known as the foundation of the design. These rules govern everything within the PCB structure and generally fall into two camps: performance and manufacturability. Setting this foundation correctly is extremely important and the key to success.

Connect the Dots: Sequential Lamination in HDI PCB Manufacturing
07/31/2025 | Matt Stevenson -- Column: Connect the DotsAs HDI technology becomes mainstream in high-speed and miniaturized electronics, understanding the PCB manufacturing process can help PCB design engineers create successful, cost-effective designs using advanced technologies. Designs that incorporate blind and buried vias, boards with space constraints, sensitive signal integrity requirements, or internal heat dissipation concerns are often candidates for HDI technology and usually require sequential lamination to satisfy the requirements.
Target Condition: The 5 Ws of PCB Design Constraints
07/29/2025 | Kelly Dack -- Column: Target ConditionHave you ever sat down to define PCB design constraints and found yourself staring at a settings window with more checkboxes than a tax form? You’re not alone. For many designers—especially those newer to the layout world—the task of setting up design constraints can feel like trying to write a novel in a language you just started learning.
