iNEMI Call-for-Participation Webinar Conformal Coating Evaluation for Improved  Environmental Protection Project, Phase 3

iNEMI is organizing the third phase of its highly successful Conformation Coating Evaluation for Improved Environmental Protection project. Conformal coatings are used to protect printed circuit boards (PCB) and components mounted on them from the damaging effects of moisture, particulate matter, and corrosive gases. The objective of Phase 3 is to develop and expedite a quantitative test for evaluating conformal coating performance on test vehicles that resemble the actual hardware.
Phases 1 and 2 established a quick quantitative test for characterizing the performance of conformal coatings using planar test vehicles consisting of Cu and Ag serpentine thin films. However, the serpentine films are on silicon, not on PCB-like surfaces. Furthermore, the test vehicles are not representative of the 3D structure of actual PCB assemblies. Phase 3 plans to:
  • Design test vehicles with 3D structures on PCB substrates, including interface electronics for measuring and heating the test vehicle.
  • Enable comparison of different coating materials, thicknesses, and cleaning methods by testing with flowers-of-sulfur (FoS), mixed flowing gas (MFG) and iodine vapor test (IVT) during corrosion exposure. 
  • Work with standards-making bodies to incorporate coating performance evaluation testing into industry standards.
The project will be chaired by Marko Pudas (Picosun, an Applied Materials Company) and co-chaired by Prabjit Singh (IBM). Sign-up deadline is December 31, 2022.
This webinar is open to industry; advance registration is required. Two sessions (with the same content) are scheduled (see below). If you have any questions, please contact Haley Fu (
