Home/Technical Glossary/UnibondĀ® UnibondĀ® Unibond electrodes are used for parallelĀ gap bonding and reflow soldering.Ā Generally, RWMA2 copperĀ UnibondĀ electrodes are used with resistive and/orĀ hard materials such as gold plated kovarĀ and nickel. MolybdenumĀ Unibond electrodes are used for bonding conductiveĀ or soft materials such as copper or gold. The face of aĀ UnibondĀ electrode is 0.020Ā inches (0.5 mm) wide by 0.030 inchesĀ (0.75 mm) deep. In unfixtured applications,Ā this limits their use to bonding ribbonsĀ (wire) which are at least 0.010 inches (0.25Ā mm) wide because of the limited visibility. For more information read ourĀ Unitip/UnibondĀ datasheet.
