Contact factory for additional details as required. 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 GaAs MMIC devices are susceptible to damage from Electrostatic Discharge. Proper precautions should be observed during handling, assembly and test. TriQuint Semiconductor Texas : Phone (972)994 8465 Fax (972)994 8504 Web: www.triquint.com 5
