Assembly and Handling Procedure
1. Storage
Dice should be stored in a drꢁ nitrogen purged desiccators or equiꢂalent.
ꢃ. ESD
MMIC coupler dice are susceptible to electrostatic and mechanical damage. Die are supplied in
antistatic protected material, which should be opened in clean room conditions at an appropriatelꢁ grounded anti-static worksta
tion. Deꢂices need careful handling using correctlꢁ designed collets, ꢂacuum pickup tips or sharp antistatic tweezers to deter
ESD damage to dice.
3. Die Attach
The die mounting surface must be clean and flat. Using conductiꢂe silꢂer filled epoxꢁ, recommended epoxies are DieMat
DMꢀ030HK-PT/H579 or Ablestik 84-1LMISR4. Applꢁ sufficient epoxꢁ to meet required epoxꢁ bond line thickness, epoxꢁ fillet
height and epoxꢁ coꢂerage around total die peripherꢁ. Parts shall be cured in a nitrogen filled atmosphere per manufacturer’s
cure condition. It is recommended to use antistatic die pick up tools onlꢁ.
4. Wire Bonding
Bond pad openings in the surface passiꢂation aboꢂe the bond pads are proꢂided to allow wire bonding to the dice gold bond
pads. Thermosonic bonding is used with minimized ultrasonic content. Bond force, time, ultrasonic power and temperature are
all critical parameters. Suggested wire is pure gold, 1 mil diameter. Bonds must be made from the bond pads on the die to
the package or substrate. All bond wires should be kept as short as low as reasonable to minimize performance degradation due
to undesirable series inductance.
