Halogen-free hard gold PCB finish is an increasingly popular choice in the electronics industry, particularly for applications requiring high reliability and environmental sustainability. This finishing technique combines the benefits of hard gold plating with the eco-friendly aspects of halogen-free materials.
The hard gold finish provides excellent conductivity, corrosion resistance, and wear resistance, making it ideal for high-performance electronic devices. Unlike soft gold, hard gold is alloyed with small amounts of other metals, typically cobalt or nickel, to increase its hardness and durability. This allows for multiple insertion cycles without significant wear, crucial for components that require frequent connections or testing.
The halogen-free aspect of this finish addresses growing environmental and health concerns associated with halogenated compounds. By eliminating halogens such as chlorine and bromine, which are often found in traditional PCB materials, this finish reduces the potential for toxic emissions during manufacturing and disposal processes.
Furthermore, halogen-free hard gold finishes often comply with stringent international regulations like RoHS (Restriction of Hazardous Substances) and REACH (Registration, Evaluation, Authorization and Restriction of Chemicals), making them suitable for global markets and environmentally conscious consumers.
This combination of durability, performance, and environmental responsibility makes halogen-free hard gold PCB finish an excellent choice for a wide range of applications, from consumer electronics to aerospace and medical devices.
