Hanlding and Mounting Information
Handling
All semiconductor dice should be handled with care to avoid
damage or contamination. For an individual die, the use of
plastic tipped tweezers or vacuum pick-up tool is recommended.
When using automatic pick and place, abrasion and mechanical
shock should be minimized.
Mounting
The dice have Ti-Pt-Au back metal, with a final gold thickness
of 0.1 micron. They can be die mounted with a gold-tin eutectic
solder preform or conductive epoxy. The mounting surface
must be clean and flat.
Eutectic Die Attachment
An 80/20 gold-tin eutectic solder preform is recommended with
a work surface temperature of 255
°
C and a tool tip temperature
of 265
°
C. When hot gas is applied, the tool tip temperature
should be 290
°
C. The chip should not be exposed to tempera-
tures greater than 320
°
C for more than 20 seconds. No more
than three seconds should be required for attachment.
Epoxy Die Attachment
A minimum amount of epoxy should be used. A thin epoxy
fillet should be visible around the perimeter of the chip after
placement. Cure epoxy per manufacturer’s schedule.
Wire Bonding
The two bond pads on these die have a Ti-Pt-Au metalization
scheme, with a final gold thickness of 2.5 microns. The pads are
75 x 150 microns; up to two wires or a 100 micron wide ribbon
can be bonded to each pad. Thermosonic wedge wire bonding of
0.001” diameter gold wire is recommended with a stage temper-
ature of 150
°
C and a force of 25 to 40 grams. Ultrasonic energy
should be adjusted to the minimum required.
