Follow the Story: How to Increase Your Supply Chain Intelligence

07/10/2026 | I-Connect007 Editorial Team
For years, supply chain management was largely about efficiency: securing materials, managing inventory, and delivering products on time. Today, it's much more complex. First, AI is reshaping demand forecasting and materials sourcing. We also feel the impact of trade policies on manufacturing decisions, and government advocacy efforts are shaping the business environment for electronics companies worldwide. Understanding these forces and how they connect is becoming a competitive advantage.

Base Material Properties and Microvia Reliability

07/01/2026 | Ed Kelley, Victory Giant Technology
The drive toward higher circuit density is challenging PCB manufacturers and their supply chains alike, with base materials as a critical foundation for complex designs. HDI designs present specific challenges and requirements for these materials, but given the myriad possible designs and applications, there is no optimal “one size fits all” material. Perhaps the most challenging HDI designs are those that use stacked vs. staggered microvias, with the number of layers of stacked microvias and the pitch between them as critical variables.

Learning With Leo: Soldering—The Interpretation Problem

06/30/2026 | Leo Lambert -- Column: Learning With Leo

I’ve spent most of my career on the training floor and in the rooms where IPC standards get written and revised. Every week, engineers, operators, inspectors, and quality teams come to us from across the country and across industries for help, and they bring their toughest questions. On the surface, they’re asking about toe fillets, gold plating, or rework limits. But underneath those questions is something more important: uncertainty about reliability.
