Tin plated craft gift sheet metal stamping part
Tin plating and its alloy is a kind of coating with good solderability and certain corrosion resistance, widely used in electronic components and printed circuit boards. In addition to physical methods such as hot dip and spraying, electroplating, dip plating and chemical plating have been widely used in industry because of their simplicity.

Advantages of Acid bright tin plating:
1. Tin is reduced by bivalent, saving electricity consumption;
2. Plating bath has high conductivity, low bath current and high current efficiency;
3. The operating temperature is close to room temperature, without heating equipment;
4. Gloss coating can be obtained by using appropriate additives;
5. Less damaging to the substrate.
Disadvantages:
1. Operation and bath management need to be very careful to get a good coating.
2. Additives are needed, otherwise it is easy to produce branches or nodular coatings.
3. Insoluble anodes cannot be used.
4. Corrosive, plating tank must be rubber lining.
5. Tin divalent may oxidize to tin tetravalent and become blunt.
