We have occasionally worked with customers who have had problems with "chip bonder" types of adhesives. In a number of cases, we found the adhesives to either contain a high level of chloride or had an outgassing product (from the cure reaction) which were high in chloride. High levels of chloride will contribute to electrical leakage, as well as metal migration and corrosion. 2. Can the glue be conductive for at least fine pitch devices? I think it is not so much a case of a conductive (by design) material, but that the material contains enough halides to be harmful. Hope this helped.
