MAAM71100 GaAs MMIC Power Amplifier 7.0 - 11.0 GHz Handling Procedures Permanent damage to the MAAM71100 may occur if the following precautions are not adhered to: Rev. V6 Outline Drawing A. Cleanliness - The MAAM71100 should be handled in a clean environment. DO NOT attempt to clean assembly after the MAAM71100 is installed. B. Static Sensitivity - All die handling equipment and personnel should comply with DOD-STD1686 Class I. C. Transients - Avoid instrument and power supply transients while bias is connected to the MAAM71100. Use shielded signal and bias cables to minimize inductive pick-up. D. General Handling - DO NOT touch the surface of the die. It is recommended that the MAAM71100 die be handled along the long side with a sharp pair of tweezers. Mounting The MAAM71100 is back-metallized with Pd/Ni/Au (100/1, 000/30,000Å) metallization. It is recommended that the die be mounted with Au/Sn eutectic preforms. The attachment surface should be clean and flat. A. An 80/20 preform is recommended with a work surface temperature of approximately 255°C and a tool temperature of 265°C. When hot 90/5 nitrogen/hydrogen gas is applied, solder temperature should be approximately 290°C. B. DO NOT expose the MAAM71100 to a temperature greater than 320°C for more than 20 seconds. No more than 3 seconds of scrubbing should be required for attachment. Typical Bias Configuration 3,4,5 VDD (VD1, VD2) 1000 pF Min. RF OUT RF IN Bonding A. Ball or wedge bond with 1.0 mil diameter gold wire of 3.0 mil x 0.5 mil ribbon. Thermosonic bonding with a nominal stage temperature of 150°C and a ball bonding force of 40 to 50 grams or wedge bonding force of 18 to 22 grams is recommended. Ultrasonic energy and time should be adjusted to the minimum levels necessary to achieve reliable bonds. B. Bonds should be started on the die and terminated on the package. C. Bonding pads are 4.0 x 4.0 mils minimum. VGG (VG1, VG2) 3. Nominal bias is obtained by first connecting -1.2 volts to pads VG1 and VG2 followed by connecting +8 volts to pads VD1 and VD2 (note sequence). 4. The recommended VDD range is +6 to +9 volts. 5. Optional on-chip resistor networks are used by connecting a nominal –5 volts to pad “A” and connecting pad “B”, “C”, “D”, or “E” to pad VG1; and VG2. 3 ADVANCED: Data Sheets contain information regarding a product M/A-COM Technology Solutions • North America Tel: 800.366.2266 • Europe Tel: +353.21.244.6400 is considering for development.
