Environmental protection copper Tin Plated Spot Welding Stud.
Welding studs refers to the method of welding metal studs or other similar metal parts (bolts, nails, etc.) to the workpiece (usually plate) is called stud welding, and the stud used for welding here is called welding Studs.
Dip plating is to immerse the workpiece in a solution containing the metal salt to be plated, and deposit a metal coating on the surface of the workpiece according to the principle of chemical displacement. This is different from the general electroless plating principle, because the plating solution does not contain reducing agent. It is not the same as contact plating. When the workpiece is immersed in the metal salt solution to be plated, it must be closely connected with an active metal. The active metal enters the solution to release electrons, and the metal ions with higher potential in the solution get electrons. Deposited on the surface of the workpiece.
Tin plating and its alloy is a kind of coating with good solderability and certain corrosion resistance, which is widely used in electronic components and printed circuit boards.
Advantages of tinning:
1. Tin is reduced by the second price, which saves electricity;
2. The plating bath has high conductivity, low bath voltage and high current efficiency;
3. If the operating temperature is close to room temperature, heating equipment is not required;
4. Use appropriate additives to obtain a glossy coating;
5. Less damage to the substrate.
