This product is an aqueous iodine/potassium iodide gold etchant (potassium iodide 10–<20% w/w; iodine 5–<10% w/w). Aluminum (Al) is generally incompatible, while chromium (Cr) and alumina (Al2O3) are typically compatible. Palladium (Pd), cobalt (Co), and platinum (Pt) may be affected, depending on conditions. Each metal should be considered at risk unless confirmed stable by experimental testing.

General description
Nickel compatible gold etchant is an etching solution that can be used in the removal of the gold layer from the surface. Compatibility of gold etchants with nickel allows it to be utilized in applications where nickel is used as a dominant material in the fabrication of micro-electro-mechanical systems (MEMS).
Application
Elective general-purpose etchant for gold. Compatible with negative and positive photoresists.
Features and Benefits
Etching readily controlled with minimum undercutting. Room temperature operated. Cyanide-free, no attack of nickel films.
