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 wi re or ribbon bonds made to the pads.
Solder Die Attach:
Solder which does not scavenge gold, such as Indalloy # 2, is recommended. Sn-Pb based solders are not rec-
ommended due to solder embrittlement. Do not expose die to a temperature greater than 235°C, or greater than
200°C for longer than 10 second s. No more than three seconds of scrubbing should be required for attach ment.
Epoxy Die Attach:
Assembly can be preheated to 125 - 150°C. Use a minimum amount of epoxy. Cure epoxy as per manufac-
turer’s schedule. For extended cure time s, temperatures should be kept below 200°C.
Handling Procedures
The following precautions sho uld be observed to avoid damaging these chips:
Cleanliness: The chips should b e han dled in a clean environment.
Do not attempt to clean die after installation.
Static Sensitivity: Schottky barrier diodes are ESD sensitive and can be damaged by static
electricity. Proper ESD te chniques should be used whe n handling these devices.
General Handling: The protective polymer coating on the active areas of these die pro v ides scratch
protection, particularly for the metal air bridge which conta cts the anode. Die can
be handled with tweezers or vacuum pickups and are suitable for use with
automatic pick-and-place equipment.
