Controlling ionic contamination is a long‑established element of electronic assembly reliability. In automotive electronics manufacturing, ROSE (Resistivity of Solvent Extract) testing is widely applied and generally regarded as sufficient once a manufacturing process has been qualified based on electrical testing under conditions of damp heat. At the same time, ionic chromatography (IC) provides far greater analytical resolution, prompting discussion about potential benefits and drawbacks. Building on a recent technical session at AEPC 2026, this panel examines the role, limitations, and appropriate use of IC analysis in ECU manufacturing.

Introduction to PCB Design I for electronics manufacturing

Design high-speed PCBs that maintain signal integrity, reduce noise, and perform reliably under real operating conditions.

When properly integrated into the PCB structure, HDI improves both signal integrity and via reliability. The success or failure of product performance, reliability, and time to market is heavily influenced by the materials, processes, and designs of these enabling technologies.
