Description

The corrosion-chemical foil for aluminum electrolytic capacitors is a special electronic material for basic components of the electronic information industry.

The electrode plates are connected to the negative pole of the power supply, and the power-on roller is connected to the positive pole of the power supply. The power-on roller is in direct contact with the aluminum foil, and the aluminum foil is electrified by the electrification rod for electrolytic corrosion.

[0003] The existing aluminum foil electrolytic corrosion device still has some shortcomings, such as: 1.
