The samples are 5 pieces of circuit boards that have been cut. From the photos, we can find that the soldering aid is very obvious and difficult to remove by conventional methods.

Parameters in the first test

Number of cleaning pieces: 2 pieces

Cleaning pressure: 15MPa.

CO2 flow rate: slightly

Cleaning time: 20 minutes
