Operation
• Turn on equipment, turn on N2 gas
• Setup configuration
• Clamp sample on the workholder & heat it if necessary
• Bond first point: Take the handle bar, gently touch the pad, hear a beep, the ultrasonic power is applied to melt gold wire to the pad
• Move from front to back with a loop: when the handle is lifted, clamp opens; when tool is lowered to some extend, clamp is closed, then the length of the wire can’t be changed.
• Bond second point and break the wire

Pick & Place Tool
•Model 7316B/7200B Series, •Dual Head Die Bonders, •Manual X-Y-Z
This machine with tool heads for dispensing epoxy and for pick up and placement of dice. Die rotation and radiant heat to the tool are both included. A third head with a vacuum capillary tool for pick and place of preforms is also included. Exchange of this head for the epoxy dispense head converts this machine from epoxy to eutectic preform bonding. Mechanical scrub motion for the bond head, driven by the transfer motor, is programmable in both amplitude and number of repetitions: Bonding force is adjustable by a low rate coil spring.
