Bond HeadAt a Glance
www.palomartechnologies.com© Palomar Technologies, Inc.
The de-spooler rides on theta so that wire and ribbon will not get twisted during bonding. This is unique to Palomar Technologies.
26
Bond HeadAt a Glance• Bond force is applied
using a robust, low maintenance voice coil bond head Force range: 3 gram to 200 gram
• Maximum Ѳ rotation range: 390 degree
www.palomartechnologies.com© Palomar Technologies, Inc.
Axis Resolution • XYZ are all 0.1um• Theta 0.01125 degree
27
Process View Camera• Used for many different functions since it rides on theta which
is carried by Z-coarse• View the bond tool at all theta angles• Simply check the wire and tail position under the tool without
the need for a microscope• Although, we do have a microscope, it is much more efficient
and faster to just look in the process view camera• Other functions
– Watching loop formation during bonding– Viewing wires from an angle to see wire profile, and
inspecting wires at backside orientations that a microscope cannot see
www.palomartechnologies.com© Palomar Technologies, Inc.
28
Process View Camera• Example of the lookdown
targeting camera on the left and the process view camera on the right
• These two images are available at the same time and allow the operator to inspect the bonds from the top down using the targeting camera and to also see if the wire is in the tool using the process view camera
• Note: The process view camera can also be used to thread the tool. The image shows the wire just after rethreading
www.palomartechnologies.com© Palomar Technologies, Inc.
29
Changing Clamp Angles
No need for an expensive bond head change! Simply change the clamp.• Loosen screw for angle adjust and adjust
for position of clamp relative to tool• The rest of the bond head remains the
same

displaying parent-child part relationships
• “Who caries who” – clear understanding of which materials/wires/bond pads are dependent upon others
• Intuitive wizard to simplify calibration, set-up and programming
• New element are graphically displayed in real-time on the Part Graphic Display
www.palomartechnologies.com© Palomar Technologies, Inc.
46www.palomartechnologies.com© Palomar Technologies, Inc.
Part Graphical Display(PGD)
• “You are here” aspect of the program and build design
• True, graphical representation of build
• Excellent reference for a manufacturing document
Ex: export number or wires in seconds rather than manual counting from tree structure
• Interactive approach to ease the reference points between program tree structure and MMI
Can toggle between PGD to corresponding wire in tree structure“Lock” view to zoom in/outHighlight parent-child related parts
47www.palomartechnologies.com© Palomar Technologies, Inc.

Touch Screen• i2GI supports both traditional track-
ball control and a bright, large touch screen
• Glove-touch compatible• Crisp, clear high fidelity graphics in
multiple dynamic panes in a single view
• Vertical orientation– Enhances user control– Minimizes need for archaic hardware,
such as joysticks– Efficient, clean and reduced machine
footprint– 22 to 24” diagonal monitor
www.palomartechnologies.com© Palomar Technologies, Inc.
49
Program Compatibility• 8000 programs can be transferred to the 9000 operating platform
– The parts with references and bond sets are direct mapping matches– The user then creates wedge wire sets with proper bond and loop
parameters• For example, a program may have many components in a package that share
die that have both ball bond and wedge bond wires on the same die– This would mean that you could generate a program structure with all of
the parts– This program could then be used as a starting point for the 8000 and 9000– On each machine, the process engineer would then add bonds sets and
wire sets specific to the machine—there would be no reason to then share the programs across machines any longer
Process Development Consulting offers in-house process advancements and decades of expertise in machine, process and materials for seamless program transfers

Summary
63© Palomar Technologies, Inc.
• Modern wedge bond requirements demand an automated, large bonding area system with scalability to increase production capacity without limiting performance
• Programmers and operators should experience real-time build and production feedback to increase efficiency and decrease costs
• Lab managers should have peace of mind that their bonder is fully supported by a highly trained team of field service and process development consultants
• Precision, reliability and consistency should be inherent to the system’s capabilities

Technology Overview 5
Height learning and running• Height learning – Competitors have to touch onto
the die surfaces to measure the expected heights during programming or editing. (Customers do not like this)
• Palomar learns height automatically when focused
• Runtime automatic touching and search tolerance optimization
• Autofocus and part height update adjust expected height based on a autofocus
