The time of the tinning process mainly depends on the process method used. At present, the methods of tinning copper surface include copper electroplating tinning process and copper chemical tinning process.
Copper electro-tinning process
The copper electro-tinning process requires electricity and professional electroplating equipment. Its basic process includes degreasing, chemical polishing, electro-tinning, alkali neutralization and tin protection. The electroplating time is usually about 20 minutes, and the specific time depends on the current density and the size of the workpiece.
Copper chemical tinning process
The copper chemical tinning process is simple to operate and does not require heating, electricity and professional equipment. It only needs to immerse the workpiece in the tinning solution. The processing time is generally between 15 seconds and 120 seconds, and the specific time depends on the use temperature and processing time of the tinning solution.
Influencing factors
Temperature of tinning solution: usually between 20 degrees Celsius and 60 degrees Celsius, it is recommended to use it at room temperature.
Processing time: The electroplating time is about 20 minutes, and the chemical tinning processing time is between 15 seconds and 120 seconds.
Through the above information, you can better understand the time requirements of the tinning process and its influencing factors.
