(2) a critical component is any component of a life support device or system whose failure to perform can be reasonably expected to cause the failure of the life support device or system, or to affect its safety or effectiveness. esd - gallium arsenide (gaas) devices are susceptible to electrostatic and mechanical damage. die are supplied in anti- static containers, which should be opened in cleanroom conditions at an appropriately grounded antistatic workstation. devices need careful handling using correctly designed collets, vacuum pickups or, with care, sharp tweezers. die attachment - gaas products from mimix broadband are 0.100 mm (0.004") thick and have vias through to the back- side to enable grounding to the circuit. microstrip substrates should be brought as close to the die as possible. the mounting surface should be clean and flat. if using conductive epoxy, recommended epoxies are tanaka ts3332ld, die mat dm6030hk or dm6030hk-pt cured in a nitrogen atmosphere per manufacturer's cure schedule. apply epoxy sparingly to avoid getting any on to the top surface of the die. an epoxy fillet should be visible around the total die periphery. for additional information please see the mimix "epoxy specifications for bare die" application note. if eutectic mounting is preferred, then a fluxless gold-tin (ausn) preform, approximately 0.001 2 thick, placed between the die and the attachment surface should be used. a die bonder that utilizes a heated collet and provides scrubbing action to ensure total wetting to prevent void formation in a nitrogen atmosphere is recommended. the gold-tin eutectic (80% au 20% sn) has a melting point of approximately 280o c (note: gold germanium should be avoided). the work station temperature should be 310oc +/- 10o c. exposure to these extreme temperatures should be kept to minimum. the collet should be heated, and the die pre-heated to avoid excessive thermal shock. avoidance of air bridges and force impact are critical during placement. wire bonding - windows in the surface passivation above the bond pads are provided to allow wire bonding to the die's gold bond pads. the recommended wire bonding procedure uses 0.076 mm x 0.013 mm (0.003" x 0.0005") 99.99% pure gold ribbon with 0.5-2% elongation to minimize rf port bond inductance. gold 0.025 mm (0.001") diameter wedge or ball bonds are acceptable for dc bias connections. aluminum wire should be avoided. thermo-compression bonding is recommended though thermosonic bonding may be used providing the ultrasonic content of the bond is minimized. bond force, time and ultrasonics are all critical parameters. bonds should be made from the bond pads on the die to the package or substrate. all bonds should be as short as possible. ordering information xr1007-bd-000x where ?x? is rohs compliant die packed in ?v? ? vacuum released gel paks or ?w? ? waffle trays xr1007-bd-ev1 xr1007-bd evaluation module october 2008 - rev 13-oct-08 mimix broadband, inc., 10795 rockley rd., houston, texas 77099 tel: 281.988.4600 fax: 281.988.4615 mimixbroadband.com characteristic data and specifications are subject to change without notice. ? 2008 mimix broadband, inc. export of this item may require appropriate export licensing from the u.s. government. in purchasing these parts, u.s. domestic customers accept their obligation to be compliant with u.s. export laws. r1007-bd caution: esd sensitive appropriate precautions in handling, packaging and testing devices must be observed. proper esd procedures should be followed when handling this device.
