This is a brief description of our Gold process:

• Electrolytic gold is typically used for minimum contact resistance, connector tabs requiring wear-ability and lubricity, or for gold wire bonding.
• Our Hard Gold meets the requirements of MIL-DTL-45204 and ASTM B 488, Types 1 and 2, Code C with a hardness range of 130-200 Knoop.  The Gold purity is a minimum of 99.7%.  Typical Hard Gold thickness's range between 5-200 uin.  Most contact fingers require 30-50 uin.
• Our Soft Gold meets the requirements of MIL-DTL-45204 and ASTM B 488, Type 3, Code A with a hardness range of 90 Knoop maximum.  The Gold purity is a minimum of 99.9%.  Typical Soft Gold thickness's for wire bonding range between 10-100 uni depending on thermosonic or ultrasonic wire bonding applications.
• Our baths are highly purified and tested for purity and hardness monthly.  Our Soft Gold is wire bond tested monthly.
