The Au-Sn eutectic bonding process is achieved at 300°C with a bond pressure of 2 MPa by using a sealing alloy thickness less than 1.5 μm. The package pressure is characterized to be around 250 mTorr, without any getter activation.
Web: The electrochemistry of copper, silver, gold, gallium, indium, thallium, and their ions, and of chlorine and bromine in fused AlCl3-NaCl-KCl was investigated by electromotive force (e.m.f) and voltammetric techniques. Univalent oxidation states were observed for all the metals. In addition, copper was further oxidized to the divalent species while gallium and … WebAIM’s Au80/Sn20 alloy is composed of 80% gold and 20% tin. Au80/Sn20 is a eutectic alloy with a melting point of 280°C (536°F) for soldering to gold surfaces.FEATURES & BENEFITSTypical applications include plating, corrosion protection, and use as a base for soldering to micro-electronics, wave solder, and SMT printed circuit board assemblies.
