Model 3436F Series: Automatic, Gantry, Large Area, Rotary Head Bonders
Last revised: 09/14/10
Application and Function :
Series 3436F models are rotary wire bonders of a gantry design. A moving and rotating bond head brings the bonding function to the work, allowing the material handling to occur under customer control. This open structure, along with a large bondable area, places very little limit on the size of the work.
Arrays of fine wire connections are bonded automatically per device program. Targeting is aligned by pattern recognition, and position is adjusted by optical encoders. Bond quality and consistency, as well as loop shape are exceptional through a combination of fine vertical axis motions, software control and ultrasonics. Process control is further aided by missing wire detection, which functions without work contact.
Models of this series allow for wedge bonding with angled wire feed and vertical feed, for deep access work. Quick conversion between these methods occurs by exchange of clamp assemblies. In both configurations, a motorized despooler pays out bond wire with zero drag.
Programming and Interface :
All input for programming and bonding operation occurs through use of a mouse, a keyboard and a control-switch pad. The graphical user interface consists of many screen forms, all displayed on a single color LCD. This display also presents embedded views from the pattern recognition camera.
User data of machine configuration, and of device targets and image patterns, can be saved externally.

Protection against Electrostatic Discharge is implemented by finishing exposed tool assemblies and other moving parts by Electroless Nickel plating, which is conductive; and all exposed painted parts with a powder-coated paint that is dissipative (1 - 10 MΩ).
workholders are not included, and are priced separately. A large number of previously designed special work holders are available. Those with Status of Current can be selected for delivery in the same time span as the machine, while those of Status Available Not Stocked must be ordered separately. Workholders 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.
West·Bond K~1200D / 1201D (recommended; not included)
50 psi; dry air
regulating valve & pressure gauge provided. Connection is via 1/4-inch tubing.
22 in/Hg min. (if needed for vacuum clamping workholder)
50-60 Hz, single-phase, either 115 VAC or 230 VAC [input must be configured at the factory for 230 VAC]. A fuse and three-prong power cord connector is provided for 115 VAC; for 230 VAC, these must be changed to conform to local requirements.
