Mounting Techniques
These chips were designed to be inserted onto hard or soft
substrates with the junction side down. They can be
mounted with conductive epoxy or with a low temperature
solder preform. The die can also be assembled with the
junction side up, and wire or ribbon bonds made to the pads.
Solder Die Attachment
Solder which does not scavenge gold, such as Indalloy #2, is
recommended. Sn-Pb based solders are not recommended
due to solder embrittlement. Do not expose die to a
temperature greater than 235°C, or greater than 200°C for
longer than 10 seconds. No more than three seconds of
scrub should be required for attachment.
Epoxy Die Attachment
Assembly can be preheated to 125 - 150°C. Use a minimum
amount of epoxy. Cure epoxy per manufacturer’s schedule.
For extended cure times, temperatures must be kept below
200°C.
Handling Procedures
The following precautions should be observed to avoid
damaging GaAs Flip-Chips:
Cleanliness
These chips should be handled in a clean environment. Do
not attempt to clean die after installation.
Static Sensitivity
Varactor diodes are ESD sensitive and can be damaged by
static electricity. Proper ESD techniques should be followed
to when handling these devices.
General Handling
The protective polymer coating on the active areas of these
dice provides scratch protection, particularly for the metal
airbridge which contacts the anode. Dice can be handled
with tweezers or vacuum pickups and are suitable for use
with automatic pick-and-place equipment.
