Handling and Assembly Information
CAUTION!
- Mimix Broadband MMIC Products contain gallium arsenide (GaAs) which can be hazardous to the human body and the
environment. For safety, observe the following procedures:
• Do not ingest.
• Do not alter the form of this product into a gas, powder, or liquid through burning, crushing, or chemical
processing as these by-products are dangerous to the human body if inhaled, ingested, or swallowed.
• Observe government laws and company regulations when discarding this product. This product must be
discarded in accordance with methods specified by applicable hazardous waste procedures.
Life Support Policy
- Mimix Broadband's products are not authorized for use as critical components in life support devices or
systems without the express written approval of the President and General Counsel of Mimix Broadband. As used herein: (1) Life
support devices or systems are devices or systems which, (a) are intended for surgical implant into the body, or (b) support or sustain
life, and whose failure to perform when properly used in accordance with instructions for use provided in the labeling, can be
reasonably expected to result in a significant injury to the user. (2) A critical component is any component of a life support device or
system whose failure to perform can be reasonably expected to cause the failure of the life support device or system, or to affect its
safety or effectiveness.
ESD
- Gallium Arsenide (GaAs) devices are susceptible to electrostatic and mechanical damage. Die are supplied in antistatic
containers, which should be opened in cleanroom conditions at an appropriately grounded anti-static workstation. Devices need
careful handling using correctly designed collets, vacuum pickups or, with care, sharp tweezers.
Die Attachment
- GaAs Products from Mimix Broadband are 0.100 mm (0.004") thick and have vias through to the backside to enable
grounding to the circuit. Microstrip substrates should be brought as close to the die as possible. The mounting surface should be
clean and flat. If using conductive epoxy, recommended epoxies are Tanaka TS3332LD, Die Mat DM6030HK or DM6030HK-Pt cured in
a nitrogen atmosphere per manufacturer's cure schedule. Apply epoxy sparingly to avoid getting any on to the top surface of the die.
An epoxy fillet should be visible around the total die periphery. For additional information please see the Mimix "Epoxy Specifications
for Bare Die" application note. If eutectic mounting is preferred, then a fluxless gold-tin (AuSn) preform, approximately 0.001
2
thick,
placed between the die and the attachment surface should be used. A die bonder that utilizes a heated collet and provides scrubbing
action to ensure total wetting to prevent void formation in a nitrogen atmosphere is recommended. The gold-tin eutectic
(80% Au 20% Sn) has a melting point of approximately 280 ºC (Note: Gold Germanium should be avoided). The work station
temperature should be 310 ºC +/- 10 ºC. Exposure to these extreme temperatures should be kept to minimum. The collet should be
heated, and the die pre-heated to avoid excessive thermal shock. Avoidance of air bridges and force impact are critical during
placement.
Wire Bonding
- Windows in the surface passivation above the bond pads are provided to allow wire bonding to the die's gold bond
pads. The recommended wire bonding procedure uses 0.076 mm x 0.013 mm (0.003" x 0.0005") 99.99% pure gold ribbon with 0.5-2%
elongation to minimize RF port bond inductance. Gold 0.025 mm (0.001") diameter wedge or ball bonds are acceptable for DC Bias
connections. Aluminum wire should be avoided. Thermo-compression bonding is recommended though thermosonic bonding may
be used providing the ultrasonic content of the bond is minimized. Bond force, time and ultrasonics are all critical parameters. Bonds
should be made from the bond pads on the die to the package or substrate. All bonds should be as short as possible.
RoHS Compliant Parts
- All Mimix products are RoHS compliant unless specifically ordered with Tin-Lead finish.
