Specifications: Model 7300C Series, Single Head Die Bonders, Manual X-Y-Z Last revised: 5/24/2010

Series Overview

Application and Function :

Machines of this series enable die attach by the eutectic with mechanical scrub method. Each of the three primary functions of picking, placing and scrubbing, of both the pre-form and die, are performed with a single tool head. Precise tool motions in all three axes are operator driven by a single lever micro-manipulator, which also triggers switching between vacuum pick-up and scrub sequences. Work piece pick-up and place areas are moved into position alternately by sliding the workholder on the work platform. A delay before scrub can be programmed as needed.

Programming and Interface :

All machine configuration constants are programmable at the machine panel, prompted by a series of "screens" displayed on an LCD. Input is via a combination of selector switch and tool vertical position, measured by encoder. These values together with sequence status are displayed during bonding.

Definitions of Models of this Series

7300C	Ultrasonic Scrub, Single Collet Eutectic Die Bond Machine Values are programmed for scrub time and ultrasonic power.
7316C	Motorized Scrub, Single Collet Eutectic Die Bond Machine Values are programmed for scrub velocity, distance, direction and number of cycles.
7327C	Motorized Scrub, Hexa-Collet Eutectic Die Bond Machine Six different die collets are held on the tool head simultaneously. Advance to successive die collets is by pushbutton switch on the manipulator control. Values are programmed for scrub velocity, distance, direction and number of cycles.

ESD Protection

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).

Machine Configuration

Microscope:

Olympus SZ51-60E or Nikon SMZ660 (recommended; not included)

Illumination:

"Luxuray" #10265.00 or #10265.01 (recommended; not included)

Die Collet:

should be ordered directly from tool manufacturers (not included)

Work Holder:

workholders also are not included, and are priced separately. Quite a large number of previously designed special work holders, both heated and unheated, are available for selection from the Work holders Product List on our Website: 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.
