GOLD, ALUMINIUM & COPPER BONDING WIRE & RIBBON

Coining aluminium, copper or gold based bonding wires & ribbons are widely used in the manufacturing of semiconductor and microelectronic devices as the electrical interconnect either between a chip and substrate or between two chips. All materials used by Coining are of the highest quality, refined and alloyed to produce the properties demanded of finished wire and ribbon products.

Coining manufactures Au bond wires for low to high volume requirements with standards that are unsurpassed in the industry. Coining has perfected the process of manufacturing wires in diameters as small as 0.0005" (12.5 microns) and wires where uniformity of elongation, tensile strength and diameter are of paramount importance. The gold wire is high-purity vacuum-processed from highly refined metals. Coining also has a long-standing reputation for providing custom wire properties for specialised applications using automatic wire bonders.

In order to assure that uniform high quality bonds can be obtained are high production speeds, special controls are used in the manufacture of 1% silicon-aluminium wire. At Coining, special attention is given to the most important characteristic of high grade bonding: homogeneity. Microscopic checks of the alloy structure of the finished lots of 1% silicon-aluminium wire are routinely performed. Wire processing is also carried out under conditions that yield the ultimate in surface cleanliness and smooth finish and permits entirely snag-free de-reeling.

Heavy / large aluminium bonding wire for microelectronics is drawn from one of three materials: 5/9's pure aluminium, 4/9's pure aluminium, or 0.5% Mg aluminium alloy. The 5/9's, 4/9's and 0.5% Mg aluminium each exhibit unique properties, which can be used to overcome any unusual bonding conditions that may be experienced.

Copper Bonding Wire

Today copper wire is one of the preferred materials for wire bonding interconnects in many semiconductor and microelectronic applications. The advantages of using copper are well documented and because of these advantageous characteristics it is being used for fine wire ball bonding up to 75microns & for wedge bonding up to 250microns. It has the ability to be used at smaller diameters, producing the same performance as gold without the high material cost. Coining uses special packaging in order to protect the wire and achieve a longer shelf life.

Ribbon Products

Ribbon Products

Coining produces ribbons of pure gold and base metals for microwave and other applications. These ribbons are typically custom-manufactured to exacting specifications, producing unparalleled uniformity of width and thereby minimising snagging in the bonding wedge. As with wire, many of the base metals supplied as ribbon can be plated with other metals for PC board repair and other applications.
