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

Ablestick 84-1LMI or 84-1LMIT 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. If eutectic mounting is preferred, then a fluxless gold-tin (AuSn) preform, approximately 0.001

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 C (Note: Gold

Germanium should be avoided). The work station temperature should be 310 C 10 C. 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.
