Model 5700E brings forward the new advances of the "E" Series, notably the placement of all machine mechanism above the work plane to allow unlimited access, and the setting of axis brakes to lock on target. In this model the tool, rather than the work, is moved, both for alignment and for bonding, with the work pre-rotated. Bond heads are built around a 63 kHz ultrasonic transducer and provide full three-way convertibility.

Machines of this series bond gold wires from 0.0007 in. to 0.002 in. diameter to interconnect wire leads to semiconductor, hybrid or microwave devices. Bonds are made by the ball-wedge technique using ultrasonic energy and work piece heat. Wire is clamped and threaded vertically through a hollow capillary, allowing independent feeding action. The connection is begun with a ball formed on the end of the wire stock by electric discharge, and completed by a wedge bond under the end of the capillary tool.

The bonding mechanism is constructed of three axes, straight-line and orthogonal, stacked in an array. Two axes, X and Y, are driven by micromanipulator for positioning, then held by pneumatic brakes for bonding. The Z Axis is driven by its programmed motor to create and arch the connection. Work is aligned by microscope, with the target judged by an angled view of the tool at a search elevation just above the work. Approach to search and then down to contact can be controlled by a separate manual encoder that generates clocks to drive the Z Motor directly, or can be controlled at the keypad or by a push-button on the right-hand control. These different methods can be used interchangeably in any sequence. Microscope alignment allows direct view of and placement of all bonds with minimum movements. The work piece is aligned front-to-back on a large fixed platform. Optional rotating and adjustable height platforms are available.

The new pivoted-clamp bond tool assemblies of this series are built around K~Sine Model 27-EC, one half wave in length, operating at a nominal frequency of 63 KHZ. It is driven by K~Sine Part No. 6795 Ultrasonic Power Supply, four Watts, dual channel, with power and time set as program values. The tool assembly is mounted on a four-bar linkage, like the "B" Series, so the tool remains vertical and can be extended down to any position that tunes ultrasonically. In standard arrangement, a 0.6250-in. capillary extended 0,53125-in. below center, provides clearance of 0.28125-in. under the ultrasonic transducer stack, and 0.3750-in. everywhere else above the work plane. An alternate capillary length of 0.750-in. can be used. 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 10 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.

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 "5700EX". For use as a stand-alone complete bonding machine, the mechanism will be completed with a plain base having a bolted-on, fixed-height work platform, and will be designated as "5700E". 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 5.000 in. above table surface, approximately 22.312 in. apart, and 8.734 in. to the rear left, and 13.093 in. rear right, of the work point.

A software program controls operation of motors and other actuators, as configured by setup values, in response to operator’s inputs. It is executed by West·Bond Part No 8100 CPU, containing a Motorola 68000 microprocessor and 256 KB of nonvolatile RAM. Thirty separate buffers of bond settings for a wire type can be entered and selected during bonding by the keypad. Each wire type can have approximately 21 stitch bonds, each with its own settings of ultrasonic power, time, and ramping, and with high or low force

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. At "home", various options are enabled including a patented self-threading routine for the angled feed method.

• Model No. 5700E. This machine with a single tool assembly, Assy. No 9220, for Negative EFO ball bonding
• Model No. 5700EX. This machine, but less Base, Work Platform, and Work Holder

• Feature No. 79. Adjustable height work platform.

Protection against Electrostatic Discharge is implemented by finishing exposed tool assemblies and other moving parts by Electro less Nickel plating, which is conductive; and all exposed painted parts with a powder-coated paint that is dissipative.

The ESD protected microscope recommended for this series is Nikon SMZ660 with the new LED illuminator "Luxuray". Neither microscope nor illuminator is included. One recommended bonding tool is included.

All work holders are priced separately, and should be ordered separately. A universal unheated work holder, capable of holding most common substrate devices between a pivoted clamp lever and adjustable backstops, is maintained in stock and is available for delivery in the same time span as the machine. Quite a large number of previously designed special work holders, both heated and unheated, are available but are not stocked, and cannot be promised for delivery with the machine. These should preferably be on an order separate from the machine order, but if not, the machine order must state that partial deliveries are allowed. Work holders for new work pieces requiring custom design and fabrication will be quoted upon receipt of drawings and samples: These must be ordered on separate purchase orders.

Compressed air, regulated to 50 psig, is required. Connection is via 1/4-inch tubing.

Electrical service required is 50-60 Hz, single phase, either 115 VAC or 230 VAC; however, input must be configured at the factory for 230 VAC. A fuse and three-prong power cord connector are provided for 115 VAC: For 230 VAC, these must be changed to conform to local requirements.
