PCBA plate making is very important, gold plating, tin plating process is also very important, below we talk about various processes. Advantages and disadvantages of various coatings: First, we have to understand why nickel plating, silver plating, tin plating, tin plating, zinc plating, gold plating. We usually use tin plating and gold plating. Common: The coatings all have a common benefit of being antiseptic (improving antioxidant capacity) and playing a decorative role. Here are the differences
