mixers - double-balanced - chip 4 4 - 41 for price, delivery, and to place orders, please contact hittite microwave corporation: 20 alpha road, chelmsford, ma 01824 phone: 978-250-3343 fax: 978-250-3373 order on-line at www.hittite.com mounting & bonding techniques for millimeterwave gaas mmics the die should be attached directly to the ground plane eutectically or with conductive epoxy (see hmc general handling, mounting, bonding note). 50 ohm microstrip transmission lines on 0.127mm (5 mil) thick alumina thin fi lm substrates are recommended for bringing rf to and from the chip (figure 1). if 0.254mm (10 mil) thick alumina thin fi lm substrates must be used, the die should be raised 0.150mm (6 mils) so that the surface of the die is coplanar with the surface of the substrate. one way to accomplish this is to attach the 0.102mm (4 mil) thick die to a 0.150mm (6 mil) thick molybdenum heat spreader (moly-tab) which is then attached to the ground plane (figure 2). microstrip substrates should be brought as close to the die as possible in order to minimize ribbon bond length. typical die-to-substrate spacing is 0.076mm (3 mils). gold ribbon of 0.075 mm (3 mil) width and minimal length <0.31 mm (<12 mils) is recommended to minimize inductance on rf, lo & if ports. handling precautions follow these precautions to avoid permanent damage. storage: all bare die are placed in either waffle or gel based esd protective containers, and then sealed in an esd protective bag for shipment. once the sealed esd protective bag has been opened, all die should be stored in a dry nitrogen environment. cleanliness: handle the chips in a clean environment. do not attempt to clean the chip using liquid cleaning systems. static sensitivity: follow esd precautions to protect against esd strikes. transients: suppress instrument and bias supply transients while bias is applied. use shielded signal and bias cables to minimize inductive pick-up. general handling: handle the chip along the edges with a vacuum collet or with a sharp pair of bent tweezers. the surface of the chip has fragile air bridges and should not be touched with vacuum collet, tweezers, or fi ngers. mounting the chip is back-metallized and can be die mounted with ausn eutectic preforms or with electrically conductive epoxy. the mount ing surface should be clean and fl at. eutectic die attach: a 80/20 gold tin preform is recommended with a work surface temperature of 255 c and a tool temperature of 265 c. when hot 90/10 nitrogen/hydrogen gas is applied, tool tip temperature should be 290 c. do not expose the chip 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: apply a minimum amount of epoxy to the mounting surface so that a thin epoxy fi llet is observed around the perimeter of the chip once it is placed into position. cure epoxy per the manufacturers schedule. wire bonding rf bonds made with 0.003 x 0.0005 ribbon are recommended. these bonds should be thermosonically bonded with a force of 40-60 grams. dc bonds of 0.001 (0.025 mm) diameter, thermosonically bonded, are recommended. ball bonds should be made with a force of 40-50 grams and wedge bonds at 18-22 grams. all bonds should be made with a nominal stage temperature of 150 c. a minimum amount of ultrasonic energy should be applied to achieve reliable bonds. all bonds should be as short as possib le, less than 12 mils (0.31 mm). 0.102mm (0.004?) thick gaas mmic wire bond rf ground plane 0.127mm (0.005?) thick alumina thin film substrate 0.076mm (0.003?) figure 1. 0.102mm (0.004?) thick gaas mmic wire bond rf ground plane 0.254mm (0.010?) thick alumina thin film substrate 0.076mm (0.003?) figure 2. 0.150mm (0.005?) thick moly tab HMC260 v04.1007 gaas mmic fundamental mixer, 14 - 26 ghz
