Not Recommended for New Designs
TriQuint Recommends the TGA4509-EPU be used for New Designs
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
Reflow process assembly notes:
· AuSn (80/20) solder with limited exposure to temperatures at or above 300§C
· 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: 200§C
GaAs MMIC devices are susceptible to damage from Electrostatic Discharge. Proper precautions should
be observed during handling, assembly and test.
