In the electronics industry, adhesives are employed for the attachment and joining of components, for energy management, product safety, protection and identification, and for shielding purposes.
The task of the adhesive is not only to join the components, but also to provide for electrical conductivity, insulation, heat dissipation, sealing, protection and noise reduction. These tasks can be illustrated by the bonding of components to printed circuit boards. In a first step, the adhesive must provide for an easy and rapid application. Small and smallest components are frequently bonded by means of accurate metering devices; for this purpose, the adhesive must be resistant to thermal stress, particularly during soldering, and must level out any possible irregularities of the surface and the stress generated by the joining of dissimilar materials.
