Detecting Non-Homogenity of Electrically Conductive Adhesives

Popis výsledku v původním jazyce

With a rapid expansion of temperature-sensitive technologies, such as Organic LED light sources and displays, it is clear that a reliable and stable technology is required to mount them safely on circuit boards. From the obvious reason of thermal stress,classic soldering is unusable, as peak temperatures for these technologies are often below 100°C. This situation is usually solved by the use of Electrically Conductive Adhesives (ECA), consisting of resin (usually epoxy) matrix and conductive filler (usually silver). However, while this technology solves the temperature problem, it still poses numerous significant risks for reliability. One of such risks is non-homogenity of the adhesives. This was observed on numerous occassions and, in some combinations of ECA and curing temperature, it appeared massively, endangering even the basic dunctions of given circuits. This paper shows the observed cases od serious non-homogenity of ECAs.
