1. Heavy Silver Pcb Circuit Board's surface is made of copper to ensure efficient current flow. These metals require proper protection of the components to avoid oxidation and other corrosion. A range of surface treatment types provide varying degrees of protection against degradation. Its surface is treated with immersion silver. This treatment is mainly applied directly to the base metal of the PCB by chemical displacement. It is more affordable than ENIG and is RoHS compliant.
2. The typical thickness of immersion silver is 4-12u". Due to the interaction of copper and silver, they will eventually diffuse. It is plane welded, lead-free and RoHS compliant. Heavy Silver Pcb Circuit Board's plated holes can maintain tighter tolerances. Signal integrity applications have lower losses. Heavy Silver Pcb Circuit Board is used in LED, telecommunications, computer applications, lighting, game consoles, industrial control, power, automotive and high-end consumer electronics industries.
