Gold Wire Bonding Machine

Gold or copper wire can be used though gold is more common because its oxide is not as problematic in making a weld.

Gold wire bonding machine. Gold ball wire bonding and stitch bonding is the most widely used assembly process in the semiconductor industry to interconnect the die circuitry to the package or substrate. Then he needs to load the dummy. The kns gold wire bonders copper stud bump wire aluminium ultrasonic wedge bonding systems are very easy to operate and are ideal for universities development laboratories through to medium volume production facilities. The most common approach in thermosonic bonding is to ball bond to the chip then stitch bond to the substrate.

Kulicke soffa k s are the world leaders for automatic wire bonders. Pure gold wire doped with controlled amounts of beryllium and other elements is normally used for ball bonding this process brings together the two materials that are to be bonded using heat pressure and ultrasonic energy referred to as thermosonic bonding. Levels of automation vary from completely manual to fully automatic. Typical applications for wire wire bonders are components in hf and rf technology cob mcm hybrids optical and automotive electronics.

Next the technician needs to set the parameter of wire bonding machine and used the dummy of the lead frame which have the die for setting. This method is commonly known as thermosonic gold ball wire bonding.

It uses force power time temperature up to 150 c and ultrasonic energy. The technician needs to prepare and sets the capillary and the gold wire into machine. This gold silver wire draw machine comes with interchangeable steel reel winders for winding the drawn wire. The winding reel has a plate type clutch with ring gear and adjustable ring nut on the transmission that permits gradual start up of the machine to prevent the wire from breaking.

The machine frame has a cast iron support a metal base and a heavy duty cast iron drawing roller. The bondjet bj855 meets the increasing demands of wire bonding and contributes to easy porting through smart functions such as the bondhead memory or the chip libraries. If copper wire is used nitrogen must be used as a cover gas to prevent the copper. Ball bonding is a type of wire bonding and is the most common way to make the electrical interconnections between a chip and the outside world as part of semiconductor device fabrication.
