HMC913 v04.0913 SUCCESSIVE DETECTION LOG VIDEOAMPLIFER (SDLVA), 0.6 - 20 GHzMounting & Bonding Techniques for MMICs The die should be attached directly to the ground plane with epoxy (see HMC gen- eral Handling, Mounting , Bonding Note). 0.279mm (0.011”) Thick MMIC IP 50 Ohm Microstrip transmission lines on 0.254mm (10 mil) thick alumina thin film H substrates are recommended for bringing RF to and from the chip (Figure 1). Wire Bond 0.076mm C Microstrip substrates should be placed as close to the die as possible in order to (0.003”) - minimize bond wire length. Typical die-to-substrate spacing is 0.076mm to 0.152 mm (3 to 6 mils). As Handling Precautions RF Ground Plane LV Follow these precautions to avoid permanent damage. Storage: All bare die are placed in either Waffle or Gel based ESD protective con- SD tainers, and then sealed in an ESD protective bag for shipment. Once the sealed 0.254mm (0.010”) Thick Alumina ESD protective bag has been opened, all die should be stored in a dry nitrogen Thin Film Substrate environment. Figure 1. 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: The chip may be handled by a vacuum collet or with a sharp pair of tweezers. Mounting Epoxy Die Attach: Apply a minimum amount of epoxy to the mounting surface so that a thin epoxy fillet is observed around the perimeter of the chip once it is placed into position. Cure epoxy per the manufacturer’s schedule.
