Details
Intorduction of hard Gold
Hard Gold. We also call it Flash Gold, Electrolytic Gold, Full body Hard Gold, Tab Gold, Selective Gold.
An important Electrolytic process of hard gold is, all copper surfaces to be plated have to be electrically connected to a rectifier ( power supply), unless" gold as etch resist" process is used. Unplated copper must be covered by mask or resist. gold has grain stiffeners and brighteners added.
Advantages of hard gold
- Lead free (No Pb)
- Long shelf life
- Hard durable surface
Disadvantages of hard gold
- Expensive
- Extra processing/Labor cost inscreasing
- Use of resist / tape
- Plating/Bus bars
- Difficulty to mix with other surface finish.
- Demarcation
Applications
It is widely used for circuitboards with connectors such as PC circuitboards, hard disk circuitboards .etc
