ESD gloves and finger cots are found at nearly every electronic manufacturing facility at assembly, rework, and repair stations, worldwide. The reason for using hand coverings is twofold: to reduce the risk of transferring detrimental skin oils and salts to the PCBA; to reduce the risk of electrical shock due to static electricity buildup from clothing and the environment. There are many different glove material types, having different advantages, as well as disadvantages. Some gloves and cots are treated with powders or chemicals to help the user fit or tactile feel; however, these can be transferred to the PCBA. The transferred materials may be detrimental to the PCBA by setting up electrical leakage and/or electrochemical migration-related issues in normal field service environments. This study will look at the possible glove-related effects in normal use of introducing known contamination, using ion chromatography.
