Au HD3
Gold Bonding Wire for Universal Use and Low Loop
This wire type contains other doping
elements apart from the well estab-
lished beryllium. Due to this doping,
type HD3 has a higher strength, loop
stiffness and thermal stability than
type HD2. Loop stability can also be
guaranteed with thinner wire diame-
ters and in flatter and/or long loops.
Areas of application
Flat integrated circuits (TSOP,
TQFP, VSSOP, IC-cards,…)
Other flat product applications
Au HD3 Benefits
Low loop wire type
Soft type bonding wire of high ductility
Exact loop guiding
Mid strength type
Well proven loop stiffness and
thermal stability
Suitable for all high performance
bonding machines
For normal and high speed assembling
