Is there any good way to remove the green oil on the PCB? [Copy link]

I downloaded a device package online. After making the PCB, I found that there were no pins and no solder mask, and there was a layer of green paint on it. Is there any good way to remove the green paint on the PCB?

The method I have used so far is scraping with a knife, but my skills are not good, the efficiency is low and I am afraid of scratching it.

Is there any other quick and easy way?

Try green oil remover or sandpaper.

Green oil is difficult to handle after being heated and baked.

Use a small electric drill for grinding stones, put on a diamond grinding head and try it out.

See if the amount is large. If the amount is large, use a degreasing agent. If the amount is small, use an electric mill.

Put a diamond grinding head on the micro electric drill to grind it. It is not recommended to use solvents to remove it. It is very toxic and expensive. Fortunately, you can reprint the solder mask layer afterwards.
