Co-Authored Paper: Chris Hunt, Ling Zou (National Physical Laboratory), Phil Kinner (Electrolube)

Conformal coatings are expected to perform across all manner of environments including high humidity environments, typically 40°C/93% RH, 65°C/95% RH or 85°C and 85% RH. Until recently, there has been little attention paid to how conformal coatings and their characteristics perform under such condensing conditions. Testing has previously been confined to humidity chambers which have certain limitations in respect to this testing type.

In this Technical paper, originally presented and published at IPC Apex (Las Vegas) March 2016, a new testing method is discussed.
