As the semiconductor
industry moves to finer and finer pitches, Gaiser Tool Company has
observed an increasing demand for smaller angle-bottleneck tip diameters
and tighter dimensional tolerances. As these tip diameters and tolerances
are decreased, the limits of existing ceramic materials and machining
techniques have been tested.
As the company that invented the first ceramic capillary, Gaiser Tool
Company is pleased to offer what we believe to be the next generation
ultra fine-pitch capillary: The 1800 series. Proven
designs are available for 60µ, 70µ, 80µ, and greater pitches.
|

|

|
 |
 
|
Our advances in
manufacturing processes, materials, tolerances, and design will be evident
in your next fine-pitch application.
The new materials group and process engineering have been busy at Gaiser
Tool Company, developing near zero porosity, sub-micron average grain
size ceramic material, as well as zirconia formulations. Our high strength
materials combined with the new proprietary Process1800 produce an angle bottleneck capillary with superior
strength and rigidity, even at very small tip diameters.

Combined with the advent of the high frequency
transducer, these smaller tip diameter capillaries can be stressed to
their physical limits, and actually broken during the wire bonding
process. To address the need for increased strength and tightened
tolerances, Gaiser Tool Company has developed a proprietary new
manufacturing process: Process1800, standard in our new 1800 series
fine-pitch capillaries. |

Process1800
inherently yields a tighter tolerance capillary, with substantially
improved dimensional tolerances as well as reduced standard deviations.
The tolerances necessary for ultra fine-pitch bonding are standard in the
1800 series. Process1800
capillaries are manufactured with our sub-micron
average grain size, near-zero porosity improved ceramic material. Zirconia/alumina
materials are also available. |

Process1800
eliminates the previously standard grinding operation used to produce the
angle-bottleneck feature on a fine-pitch capillary. Process1800
imparts a
high-tension, mirror smooth, secondary alumina skin on the angle
bottleneck portion of the tool, substantially increasing shear strength
and rigidity. Increased shear strength allows Gaiser Tool Company to
produce a more robust, high-strength, small tip diameter, angle-bottleneck
capillary. Increased rigidity reduces the ultrasonic energy loss inherent
in the angle-bottleneck design, resulting in superior ultrasonic energy
transmission and a wider tuning window - ideal for high frequency
transducers. |

Process1800 eliminates
tolerance stacking when producing an angle bottleneck capillary, greatly
reducing the effective XT
tolerance range and eliminating the risk of touching adjacent loops. |
 |
 |
 |
 |
If the same T and BNH are compared, the Process1800
tool offers greater mass at WT2 for superior strength and ultrasonics. |

The Process1800
capillary is not subjected to the stresses, micro-cracking, and rough
finish left from a grinding wheel. Process1800
imparts a high-tension,
mirror smooth, secondary alumina skin on the angle bottleneck portion of
the tool.
|
 |
 |
 |
 |
The Process1800 design
features a radiused transition from the angle bottleneck to the cone. This
gradual transition provides better stress distribution for strength and a
stiffer, more rigid bottleneck for less ultrasonic energy loss. |

Like previous Gaiser
capillaries, BNH and all other dimensions can be easily customized to meet
specific applications. |
