Wire Bonding Machine Gold wire spoon Tool
Wedge Wire Bonder • Model 7400B Series • Wedge-Wedge Wire Bonders • Manual X-Y-Z Adjust bonding force N2 A heater is around the tool
Temp Controler & Workholder Temp Controler, press * and up or down arrow to adjust workholder’s temperature Workholder with rotation adaptor Power and N2 pipes Furnace Workholder with cavity inert atmosphere (N2) and rotating mirror
Control-Left side Display parameters Open clamp Or feed wire Tool heater control Move tail back/forth Memory
Operation Clamp • 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 Tool
Toughest Operation Use tweezers to get the wire through the hole in the tool Operator face the front, can’t see the hole Gold wire Tool Clamp Hole in the tool

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.
Eutectic Bonding 7316B Vaccum Vaccum Vaccum for solder Collet for picking up die
Epoxy Bonding 7200B Vaccum compressed air Vaccum for Die Change to epoxy reservoir
Air Connections • Switch at the back of machine: switch between 7316B(epoxy) and 7200B(eutectic) before operation • Compressed air, regulated to 50 psig, is required. • Connection is via ¼" tubing. • Normal shop vacuum is required with connection also to ¼ in. tubing. • Regulator is on the left back side of the machine • N2 is conntect to the right back side. It is for providing N2 atmosphere enviorment at the workholder. Regulator is also on the right back side Required Services and Dimensions: Compressed air, regulated to 50 psig, is required.
