Aluminium Bonding Ribbon

Coining produces aluminium ribbon for high power applications. These ribbons are typically custom-manufactured to exacting specifications, producing unparalleled uniformity of width and thereby minimising snagging in the bonding wedge, resulting in significant reductions of machine downtime.

In high power applications that traditionally used aluminium wire, the advantage of switching to aluminium ribbon results in increased cycle times by reducing process times, achieved by eliminating the need for multiple wire bonds in devices. For example, 8 wire bonds of 125µm diameter can be replaced by 1 ribbon bond of 1mm x 100µm. Reducing the number of bonds also increases the reliability of the end product.
