RECAUTIONS
:
GaAs devices are fragile and should be
handled with great care. Specially designed
collets should be used where possible.
To avoid damage to the devices care should
be exercised during handling. Proper
Electrostatic Discharge (ESD) precautions
should be observed at all stages of storage,
handling, assembly, and testing. These
devices should be treated as Class 1A (0-500
V) as defined in JEDEC Standard No. 22-
A114. Further information on ESD control
measures can be found in MIL-STD-1686 and
MIL-HDBK-263.

The back of the die is metallised and the
recommended mounting method is by the use
of solder or conductive epoxy. If epoxy is
selected then it should be applied to the
attachment surface uniformly and sparingly to
avoid encroachment of epoxy on to the top
face of the die and ideally should not exceed
half the chip height. For automated dispense
Ablestick LMISR4 is recommended and for
manual dispense Ablestick 84-1 LMI or 84-1
LMIT are recommended. These should be
cured at a temperature of 150
C for 1 hour in
an oven especially set aside for epoxy curing
only. If possible the curing oven should be
flushed with dry nitrogen.

Application Notes and design data including S-
parameters are available; please contact
Filtronic Compound Semiconductors Ltd.
This part has gold (Au) bond pads requiring
the use of gold (99.99% pure) bondwire. It is
recommended that 25.4
m diameter gold wire
be used. Thermosonic ball bonding is
preferred. A nominal stage temperature of
150
C and a bonding force of 40g has been
shown to give effective results for 25
m wire.
Ultrasonic energy shall be kept to a minimum.
For this bonding technique, stage temperature
should not be raised above 200C and bond
force should not be raised above 60g.
Thermosonic wedge bonding and
thermocompression wedge bonding can also
be used to achieve good wire bonds.

Die in Waffle-pack
(Gel-pak available on request)

Bonds should be made from the die first and
then to the mounting substrate or package.
The physical length of the bondwires should be
minimised especially when making RF or
ground connections.
