Reflow process assembly notes:
•=AuSn (80/20) solder with limited exposure to temperatures at or above 300ΓC
•=alloy station or conveyor furnace with reducing atmosphere
•=no fluxes should be utilized
•=coefficient of thermal expansion matching is critical for long-term reliability
•=storage in dry nitrogen atmosphere
Component placement and adhesive attachment assembly notes:
•=vacuum pencils and/or vacuum collets preferred method of pick up
•=avoidance of air bridges during placement
•=force impact critical during auto placement
•=organic attachment can be used in low-power applications
•=curing should be done in a convection oven; proper exhaust is a safety concern
•=microwave or radiant curing should not be used because of differential heating
•=coefficient of thermal expansion matching is critical
Interconnect process assembly notes:
•=thermosonic ball bonding is the preferred interconnect technique
•=force, time, and ultrasonics are critical parameters
•=aluminum wire should not be used
•=discrete FET devices with small pad sizes should be bonded with 0.0007-inch wire
•=maximum stage temperature: 200ΓC
Assembly Process Notes
GaAs MMIC devices are susceptible to damage from Electrostatic Discharge. Proper precautions should
be observed during handling, assembly and test.
Note: Devices designated as EPU are typically early in their characterization process prior to finalizing all electrical and process
specifications. Specifications are subject to change without notice.
