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.

IPC Standards Committee Reports – Packaged Electronic Components, Flex Circuits, High Speed/High Frequency, Rigid Printed Boards
December 7, 2015 | IPCEstimated reading time: 3 minutes
The D-31b IPC-2221/2222 Task Group met to advance the working draft of IPC-2226A, Sectional Design Standard for HDI Printed Boards, which is the first revision effort for this standard since its original 2003 publication. Attendees were segmented into five subgroups to work on content in sections 3 through 6.
The D-33a Rigid Printed Board Performance Task Group and the 7-31a IPC-A-600 Task Group met jointly to review and approve photographs of acceptable and nonconforming anomalies for the future “J” revision to IPC-A-600, Acceptability of Printed Boards. The photographs presented were intended to address new and expanded requirements released in the new IPC-6012D, Qualification and Performance Specification for Rigid Printed Boards.
The D-35 Printed Board Storage and Handling Subcommittee met to complete the review of industry feedback to the working draft of an “A” revision to the IPC-1601, Printed Board Handling and Storage Guidelines. The group addressed comments related to measurement of moisture content, the use of oxidation arrest paper, the impact of baking on ENEPIG and ENIG surface finishes, and recommendations for resealing opened moisture barrier bags for storage of bare printed boards. A Final Draft for Industry Review will be circulated in Q4 2015.

Siemens Expands EDA Software Access Through EuroCDP Project
05/14/2026 | SiemensSiemens has become the first software provider to sign a strategic framework agreement with the European Chips Joint Undertaking (Chips JU) which aims to bolster Europe's semiconductor industry by fostering collaboration between the EU, member states and the private sector, through the European Chips Design Platform (EuroCDP) project.
Rethinking Stackup, Materials, and Tolerances in Modern Designs
05/14/2026 | Kristin Moyer, Global Electronics AssociationThe simple rectangular rigid PCB is becoming increasingly infrequent. This reality necessitates designing with concepts well outside traditional rigid PCB methodologies. For example, the designer of wearable electronics may need to implement conductive fibers integrated into the textile material. Heads-up displays, like those in VR/AR headsets and glasses, require transparent circuitry etched into the display glass. The process of designing without a rule book usually starts with something other than the traditional board design process.

Road to Reliability: Engineering High Uptime EV Charging Infrastructure
05/13/2026 | Stanton Rak, SF Rak CompanyThe transition to EVs is no longer constrained solely by vehicle capability. Instead, it is increasingly defined by a simpler, but more unforgiving question: Will the charger work when I arrive? This high uptime does not happen by accident. As EV technology has matured, limitations in battery range, power electronics, and thermal management are no longer the primary barriers to adoption.
