Unitips are electrodes for parallel gap bonding of gold plated kovar, copper, or gold ribbons (wires) which are smaller than 0.010 inches. They are made from two pieces of molybdenum or tungsten, which are permanently bonded to an insulating spacer.

Unibond electrodes are used for parallel gap bonding and reflow soldering. Generally, RWMA2 copper Unibond welding electrodes are used with resistive and/or hard materials. Molybdenum is used for bonding conductive or soft materials.
