die. It is recommended that the MAAM71200 die be
handled along the long side with a sharp pair of
tweezers.
An 80/20 Au/Sn preform is recommended with a
work surface temperature of approximately 255°C
and a tool temperature of 265°C. When hot 95/5
nitrogen/hydrogen gas is applied, solder temperature
should be approximately 290°C.
DO NOT expose the MAAM71200 to a temperature
greater than 320°C for more than 20 seconds. No
more than 3 seconds of scrubbing should be
required for attachment.
Electrically conductive epoxy is required.
Apply a minimum amount of epoxy and place the
MAAM71200 into position. A thin epoxy fillet should
be visible around the perimeter of the die.

Ball or wedge bond with 1.0 mil diameter gold wire of
3.0 mil x 0.5 mil ribbon. Thermosonic bonding with a
nominal stage temperature of
bonding force of 40 to 50 grams or wedge bonding
force of 18 to 22 grams is recommended. Ultrasonic
energy and time should be adjusted to the minimum
levels necessary to achieve reliable bonds.
Bonds should be started on the die and terminated
on the package.
