A New Materials Paradigm
As you’ll see in this month’s issue of Design007 Magazine, slash sheets such as IPC-4101/126 were never meant to be used by designers when comparing PCB laminates. These documents were created to facilitate communication between purchasing and customer service departments. You could say that slash sheets are made for administrative purposes, not engineering.
As the captain said in 'Cool Hand Luke,' “What we’ve got here is a failure to communicate.” IPC does offer several design guidelines, created specifically for PCB designers, including one just for flexible circuits. But there isn’t such a guideline for high-speed designs.
Our expert contributors examined the development of IPC slash sheets and suggest that there is a need for new, robust material guidelines created specifically for PCB designers.
We also discuss the dangers of over-specifying materials, particularly for offshore manufacturing, as well as the many risks and trade-offs associated with laminate selection.

Seeing a Future in Mexico
07/09/2025 | Michelle Te, I-Connect007The Global Electronics Association (formerly known as IPC) has been instrumental in fostering a partnership with Guanajuato, a state north of Mexico City with 12 industrial clusters and close to 150 companies involved in electronics. This past spring, Alejandro Hernández, the undersecretary for investment promotion in Guanajuato, attended IPC APEX EXPO 2025 at the invitation of IPC Mexico Director Lorena Villanueva, where he met with several companies to discuss the opportunities available in Mexico. He is inviting electronics-related companies seeking long-term investment in a centrally located area with access to highways, railways, and ports.
The Global Electronics Association Releases IPC-8911: First-Ever Conductive Yarn Standard for E-Textile Application
07/02/2025 | Global Electronics AssociationThe Global Electronics Association announces the release of IPC-8911, Requirements for Conductive Yarns for E-Textiles Applications. This first-of-its-kind global standard establishes a clear framework for classifying, designating, and qualifying conductive yarns—helping to address longstanding challenges in supply chain communication, product testing, and material selection within the growing e-textiles industry.
IPC-CFX, 2.0: How to Use the QPL Effectively
07/02/2025 | Chris Jorgensen, Global Electronics AssociationIn part one of this series, we discussed the new features in CFX Version 2.0 and their implications for improved inter-machine communication. But what about bringing this new functionality to the shop floor? The IPC-CFX-2591 QPL is a powerful technical resource for manufacturers seeking CFX-enabled equipment. The Qualified Product List (QPL) helps streamline equipment selection by listing models verified for CFX compliance through a robust third-party virtual qualification process.
The Knowledge Base: A Conference for Cleaning and Coating of Mission-critical Electronics
07/08/2025 | Mike Konrad -- Column: The Knowledge BaseIn electronics manufacturing, there’s a dangerous misconception that cleaning and coating are standalone options, that they operate in different lanes, and that one can compensate for the other. Let’s clear that up now. Cleaning and conformal coating are not separate decisions. They are two chapters in the same story—the story of reliability.
Advancing Aerospace Excellence: Emerald’s Medford Team Earns Space Addendum Certification
