HMC8401
Data Sheet
Wire Bonding
Create ball bonds with a force of 40 g to 50 g and wedge bonds
with a force of 18 g to 22 g. Create all bonds with a nominal stage
temperature of 150°C. Apply a minimum amount of ultrasonic
energy to achieve reliable bonds. Keep all bonds as short as
possible, less than 12 mil (0.31 mm).
RF bonds made with 0.003 in. × 0.0005 in. gold ribbon are recom-
mended for the RF ports. These bonds must be thermosonically
bonded with a force of 40 g to 60 g. DC bonds of 1 mil (0.025 mm)
diameter, thermosonically bonded, are recommended.
