Non Cyanide Type Electroless Gold Plating Chemicals
 - HGS-5400 is the electroless gold plating chemicals which is non-cyanide,very stable and long life. This electroless gold plating has good wire-bonding reliability.
Features
- Non-cyanide type electroless gold plating chemicals. Gold source is sodium gold sulfite.
- Plating at various gold thickness.
- Keeping long life by analyzing and replenishing ingredients.
- Plating on fine pattern of LTCC substrates by applying HGS-5500T pre-treatment in standard process.
