Signal Integrity & Metallization
Signal integrity and additive manufacturing, particularly metallization, are hot topics in PCB design and fabrication. PCB layouts are carefully engineered to achieve specific electrical and power performance targets.
Beyond the Rulebook
What happens when the rule book is no longer useful, or worse, was never written in the first place? In today’s fast-moving electronics landscape, we’re increasingly asked to design and build what has no precedent, no proven path, and no tidy checklist to follow. This is where “Design for Invention” begins.
March Madness
From the growing role of AI in design tools to the challenge of managing cumulative tolerances, these articles in this issue examine the technical details, design choices, and manufacturing considerations that determine whether a board works as intended.

Leveraging Chemical Data More Efficiently
July 29, 2025 | Lynn L. Bergeson, Bergeson & CampbellEstimated reading time: 1 minute
Some truths transcend politics, one being that chemical data holds enduring value and is becoming increasingly essential. In the United States, regardless of which party federally controls the levers of power, it’s clear that chemical manufacturers and their customers must develop and curate robust data portfolios for their chemical inventories. The commercial imperatives driving this are undeniable and gaining traction.
Data Are Intellectual Property Assets
Data in this context includes health and safety studies, physical property information, environmental fate and transport studies, release and exposure information, and similar information beyond commercial information like financial data, product formulations, and customer lists. A key tenet of the U.S. Environmental Protection Agency’s (EPA) regulatory authority under the Toxic Substances Control Act (TSCA) is the principle that manufacturers and processors are responsible for developing adequate information regarding their chemical products. Like any valuable commodity, data needs to be protected from disclosure and managed carefully to retain its value.
The industrial chemical community has not always been as protective of its health and safety chemical data, unlike their counterparts in the agricultural chemical space. Under the Federal Insecticide, Fungicide, and Rodenticide Act (FIFRA), data supporting a registered active ingredient or pesticide product and relied upon by the EPA to maintain a registration are, for 15 years, “compensable” when cited or relied upon by third parties to support follow-on FIFRA registrations.

Connect the Dots: The Future of Designing for Reality—Pattern Plating
02/05/2026 | Matt Stevenson -- Column: Connect the DotsLast month, I discussed the outer-layer imaging process and offered tips for designers to help ensure smooth manufacturing and high-quality output. The next step in the manufacturing process is copper pattern plating, where fabrication can be tricky, and design precision is even more important. The board is now ready to have the copper traces, through-holes, vias, pads, and other elements specified in the original CAD design plated to copper thickness requirements. I will identify some key design considerations for pattern plating, break down the process, and offer design tips for a successful outcome.
