Silver plated aluminum substrate

        There are many processes for aluminum substrates used for LED lighting, such as tin spraying, gold sinking, silver sinking, gold plating, and silver plating. The most common one is tin spraying (divided into lead and lead-free). The following is an introduction to silver plated aluminum substrates:

        Silver plating on aluminum substrate is a type of aluminum substrate process, which involves electroplating a layer of silver on the surface of the aluminum substrate raw material, which can better promote the conductivity and transmission of the circuit. Silver plating on the surface of aluminum is currently the mainstream process in the market and also a trend in the development of aluminum substrates in the future.

        But the silver plated aluminum substrate has a disadvantage, it is very easy to oxidize, such as not being packaged and exposing the silver layer to the air; Direct contact with human hands; Long term non use and storage environment that does not meet requirements can easily lead to oxidation. On the other hand, the price of silver plating is relatively high and the process is complex, so it is not widely used in the current market.
