MASW2000 GaAs SPDT Switch DC - 3.0 GHz Rev. V4 Handling Procedures Bonding Permanent damage to the MASW2000 may occur if the following precautions are not adhered to: A. Ball or wedge bond with 1.0 mil diameter pure gold wire. 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 wirebonds. B. Wirebonds should be started on the chip and terminated on the package. GND bonds should be as short as possible; at least three and no more than four bond wires from ground pads to package are recommended. A. Cleanliness - The MASW2000 should be handled in a clean environment. DO NOT attempt to clean assembly after the MASW2000 is installed. B. Static Sensitivity - All die handling equipment and personnel should be DC grounded. C. Transients - Avoid instrument and power supply transients while bias is connected to the MASW2000. Use shielded signal and bias cables to minimize inductive pick-up. D. Bias - Apply voltage to either control port A1/B2 or A2/B1 only when the other is grounded. Neither port should be allowed to “float”. E. General Handling - It is recommended that the MASW2000 chip be handled along the long side of the die with a sharp pair of bend tweezers. DO NOT touch the surface of the chip with fingers or tweezers. Mounting The MASW2000 is back-metallized with Pd/Ni/Au (100/1,000/10,000Å) metallization. It can be diemounted using Au/Sn eutectic preforms or a thermally conductive epoxy. The package surface should be clean and flat before attachment. Eutectic Die Attach: A. An 80/20 Au/Sn 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 MASW2000 to a temperature greater than 320°C for more than 20 seconds. No more than 3 seconds of scrubbing should be required for attachment. Epoxy Die Attach: A. Apply a minimum amount of epoxy and place the MASW2000 into position. A thin epoxy fillet should be visible around the perimeter of the die. B. Cure epoxy per manufacturer’s recommended schedule. C. Electrically conductive epoxy is recommended but is not required. 4 ADVANCED: Data Sheets contain information regarding a product M/A-COM Technology Solutions • North America Tel: 800.366.2266 / Fax: 978.366.2266 is considering for development.
