Handling Precautions
Follow these precautions to avoid permanent damage.
2
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 sys-
tems.
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 fingers.
Mounting
The chip is back-metallized and can be die mounted with AuSn eutectic preforms or with electrically conductive
epoxy. The mounting surface should be clean and flat.
Epoxy Die Attach:
Apply a minimum amount of epoxy to the mounting surface so that a thin epoxy fillet is observed around the perim-
eter of the chip once it is placed into position.
Cure epoxy per the manufacturer’s schedule.
Wire Bonding
Ball or wedge bond with 1.0 diameter pure gold wire. Thermosonic wirebonding 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. Use
the minimum level of ultrasonic energy to achieve reliable wirebonds. Wirebonds should be started on the chip and
terminated on the package. RF bonds should be as short as possible.
