Die Attach and Bonding Procedures
Die Attach: Eutectic die attach is recommended. For eutec-
tic die attach: Preform: AuSn (80% Au, 20% Sn); Stage
Temperature: 290°C, ±5°C; Handling Tool: Tweezers; Time: 1
min or less.
Wire Bonding: Wire Size: 0.7 to 1.0 mil in diameter (pre-
stressed); Thermocompression bonding is preferred over
thermosonic bonding.
For thermocompression bonding:
Stage Temperature: 250°C; Bond Tip Temperature: 150°C;
Bonding Tip Pressure: 18 to 40 gms depending on size of
wire.

Notes: 1. Tested on Celeritek connectorized evaluation board.
2. Measured on wafer.
Notes: 1. Operation outside these limits can cause permanent damage.
2. Calculation maximum operating temperature:
Tmax = 175–(Pdis [W] x 82) [°C].
