Copper pins surface treatment and cleaning process involves the following steps:

1. Degreasing: The copperpins are first cleaned to remove any oil or grease present on their surface. This is usually done using a solvent-based cleaner or by washing with a degreasing solution.

2. Pickling: The cleaned copperpins are then pickled to remove any oxide layer on their surface, using an acid solution or a mixture of acid and salt.

3. Passivation: The pits and scratches present on the surface of the copperpins are smoothed out and their surface is passivated using an oxidizing solution to prevent further oxidation.

4. Rinse: The copperpins are then washed thoroughly with water to remove any residual acid or chemicals.

5. Drying: After washing, the copperpins are dried thoroughly using air-drying methods or by using a drying oven.

6. Lubrication: Finally, the copperpins are coated with a lubricant to prevent corrosion and improve their durability.
