WEST•BOND MODEL 454647E SERIES INSTRUCTION MANUAL

PRODUCT OVERVIEW

Bond Tool Head Assemblies

The new forward-pivot tool assemblies

of this series are built around K~Sine

Transducer, Model No. 24-W, operated

at 63 KHz. It is driven by K~Sine Part

No. 10345 Ultrasonic Power Supply,

four Watts, dual channel, with power

and time set as program values. This

transducer uses a bond tool length of

0.750". Vertical clearance is a full

0.375" everywhere under these tool heads and all other mechanism except for wire presentation at 45°

for angled feed. Wire Clamps are air-opened and spring-closed, and have self-contained closure pivots. A

separate pivot about an axis located to serve both overhead and angled feed generates the clamp

motions along their lines of feed action. To change between angled feed and overhead feed, it is

necessary only to exchange the small clamp assemblies and to change the wire drag means. Alignment

of clamps to the tool is facilitated by individual adjustments along three axes. Actuation of all clamp

motion is by the same spiral cam of an inboard motor and is transferred through the pivots of the four-bar

linkage. Appropriate clamp motion settings for each method are configured in software and are retained in

non-volatile memory. Motions toward the tool are spring-driven, while the more powerful motor drives

away from the tool – to ease concerns during set-up.

Rigid bearing mounts, rather than taper loading, fix the strut bar of this assembly so that any required

bond force can be applied. The standard set of force springs generates 15 to 250 grams, and together

with the work-sensing firing switch, is built into the four-bar linkage. A dual force mechanism, operated

pneumatically, acts to change between two pre-set force values, and either high or low force may be

programmed for any bond. Radiant tool heat with panel mounted, constant current control is included.

Machine Configuration

The mechanism of this series was designed to mount above a customer's work handling system, to be

confined entirely above the work plane, and so not to have any base or work platform. In this

configuration, a model of this series is designated as "454647EX". For use as a stand-alone complete

bonding machine, the mechanism will be completed with a plain base having a bolted-on, adjustable

height, work platform, and will be designated as "454647E". In either the "E" or the "EX" configurations,

optional control arms are included to move both the manipulator control point and the Z axis encoder

control point five inches vertically from their normal positions near the machine base to new locations

above the work plane. When the high control arrangement is used, the customer must provide suitable

operator's forearm rests. This is essential both for the operator's safety and comfort, and to provide a

stable platform from which to direct control motions with the accuracy required for wire bonding. The

manual Z Encoder method of controlling tool descent is optional.

Mounting points for the "EX" version of this mechanism are provided at two foot locations at the work

plane elevation, approximately 22.312 in. apart, and 8.734 in. to the rear left, and 13.093 in. rear right, of

the work point.

Electrical Software and Hardware

A software program controls operation of motors and other actuators, as configured by setup values, in

response to operator’s inputs. It accepts entry of data about User’s Devices to create different Types of

connections. These Types may have any number of Bonds, up to 100, and may be repeated for any

number of Wires up to the maximum of 6000 individual Bonds. Data to define all the motions required to

create the connections are stored in Buffers that are selected by the keypad. Default values are 30

PRODUCT OVERVIEW

Electrical Software and Hardware

Types of 5 Bonds per Type which yields 40 Device Buffers. WEST•BOND Part No 8100 CPU, containing a

Motorola 68000 microprocessor and 256 KB of nonvolatile RAM executes the software program.

A keypad is provided for direct entry and editing of both configuration and user data and for selection of

operation options. Entry and execution is prompted at the machine panel by a series of "screens"

displayed on a 4-line 40-character LCD. All programmed values are displayed during bonding.

Built in ultrasonic power supply is K~Sine Part No 10345, four Watts, dual channel. Settings of power

and time program values are sent via an eight-bit interface. Adjustment of current for radiant tool heat is

included with the panel controls.

Operating Controls

KEYPAD

Twelve-key pad for entry of program data, setting of Modes, and direct control of machine

actions. At left hand.

ENCODER

Generates Z-Axis motor step clocks: A home sensor parallels the G Key and the Ball Button. At

left hand with both high and low control arms.

X-Y

MANIPULATOR

Moves tool head, TV camera, and motorized slides atop X-Y-Axes with 8-to-1 mechanical

advantage. At right hand with both high and low control arms.

ALL BUTTON

Push-button switch in the manipulator control ball. Parallels the G Key but also acts to lock only

the X-Axis for scanning the bond path along the Y-Axis, front-to-back.

OTARY WORK TABLE (OPTIONAL)

Rotates about the center of tool motion range to pre-set the alignment of bonds front-to-back.

Modes of Operation

MONITOR OR MICROSCOPE

When toggled by Key 9, the bond tool moves along the W-Axis between the target position above

this bond, and a retracted position out of camera view.

Monitor: Target the beginning bond of the sequence on the television monitor screen. Move the

camera cross hairs to the bond point by the X-Y Manipulator.

Microscope: Target all bonds by direct view of the tool through the microscope.

NHIBIT AUTO

Modifies only the Full-Auto Mode. It is set for each bond during Bond Edit.

On: Full-Auto pauses at each search elevation for X-Y targeting while the key is held.

Off: Full-Auto proceeds with no pauses.

PRODUCT OVERVIEW

Modes of Operation

FULL-AUTO OR HALF-AUTO

This mode is toggled by Key 8

Full-Auto: Start by G Key or Ball Button or Z Encoder. Lock manual X-Y slides and bond all

bonds of this wire. Pausing is controlled by Inhibit Auto described above.

Half-Auto: Controlled by G Key or Ball Button or Z Encoder. This is a press and release

sequence with pauses at each search and loop elevation.

NCH MODE

Start by Zero Key. Executes Half-Auto mode except proceeds down in slow steps from each

search to contact while key is held. Available any time tool is stopped.
