USG612 is a one component, anisotropic, electrically conductive epoxy adhesive designed for electronic applications. After a rapid snap-cure at elevated temperatures in seconds with thermo-compression, it forms a structural bonding adhesive with conductivity only in z-direction while remaining insulators in the x,y-plane. This is achieved by a delicate formulation of electrically conductive filler in the adhesive matrix. USG612 is designed for flexible circuit applications, flip chip attachment, and fine pitch assembly. USG612 is dispensable and printable.

The z-direction electrical conductivity is based on the contact of the conductive filler with substrate and bump. Heat and pressure are used to trap the conductive particles between bumps and pads of the substrates.
We recommend running preliminary tests to optimize the conditions of heating temperature and compressing pressure for the particular application. Comprehensive processing instructions can be obtained by contacting directly to USGlue.com.
USG612 has a shelf life of at least 6 months when stored below -15°C in the originally sealed container. The 'Best use before end' date of each batch appears on the product label. Storage beyond the date specified on the label does not necessarily mean that the product is no longer usable. In this case however, the properties required for the intended use must be checked for quality assurance reasons.
Comprehensive instructions are given in the corresponding Material Safety Data Sheets. They are available on request from USGlue.com.
