GAISER SMALL WIRE WEDGE INFORMATION   

13. CERMET TIPPED WEDGES

Gaiser Tool Company's ongoing endeavor to provide the microelectronics industry with the finest wire bonding tools has resulted in the development of cermet tipped wedges.

The following features make cermet tipped wedges an excellent choice when selecting a tool for use with gold wire or ribbon wire.

bullet Superior performance in microwave devices with small gold wire (0.5 mil through l.0 mil)
bullet Exceptional weld attachment and tool life in gold wire bonding applications
bullet Provides excellent transfer of ultrasonic energy at lower power settings
bullet Enhances ultrasonic energy coupling
bullet Excellent for GaAs and other sensitive materials
bullet Increases tool life

GTC Figure 51-56

Figure 56. The junction line of cermet material and tungsten carbide for a Gaiser cermet wedge is approximately 1.5 microns. The very thin junction helps reduce the ultrasonic energy variance between the materials.

GTC Figure 51-57

Figure 57. The junction of the cermet material and tungsten carbide for a competitor's ceramic tipped wedge is approximately 17 microns. This larger junction increases the ultrasonic energy variance between the two materials.

GTC Figure 51-58

Figure 58. The Gaiser polished wire feed hole provides smoother wire feeding and reduces the chance of wire scratching. 

GTC Figure 51-59

Figure 59. An unpolished wire feed hold may cause inconsistent wire feeding and/or scratching of the wire.
