Vacuum Plasma Cleaner or Plasma Surface Treatment or Air Plasma Cleaner for PCB and Metal Surfaces

(1.1)The role of plasma cleaning

The principle of plasma cleaning is mainly:

(A)Etching on the surface of materials - physical effects

A large number of active particles in the plasma, such as a large number of ions, excited molecules, and free radicals, act on the surface of the solid sample, which not only removes the original contaminants and impurities, but also produces an etching effect to roughen the surface of the sample. Many fine pits are formed, increasing the surface ratio of the sample. Improve the wetting properties of solid surfaces.

(B)Activation bond energy, cross-linking

The energy of the particles in the plasma is between 0-20 eV, and most of the bonds in the polymer are between 0-10 eV.

When a solid surface is used, the original chemical bond on the solid surface can be broken, and the free radicals in the plasma and these bonds

The formation of a network of crosslinked structures greatly activates surface activity.

(C)Forming new functional groups - chemistry

If a reactive gas is introduced into the discharge gas, a complicated chemical reaction occurs on the surface of the activated material, and new functional groups such as a hydrocarbon group, an amino group, a carboxyl group, and the like are introduced, and these functional groups are all active groups, which can significantly improve the surface activity of the material.

(1.2)Advantages of vacuum plasma cleaning

Plasma cleaning is an important material surface modification method and has been widely used in many fields.

And some traditional cleaning methods, such as ultrasonic cleaning, UV cleaning, etc., have the following advantages:

(A)Low processing temperature

The processing temperature can be as low as 80 ° C - 50 ° C. Low processing temperatures ensure no thermal effects on the sample surface.

(B)No pollution during the whole process

The plasma cleaner itself is a very environmentally friendly device that does not cause any pollution,and does not cause any pollution during the treatment process.

(C)Stable processing effect

The treatment effect of plasma cleaning is very uniform and stable, and the effect of maintaining the sample after a long period of time is good.

(D)Can handle samples of various shapes

For complex shaped samples, plasma cleaning can find the right solution.

Vacuum plasma cleaning allows for the cleaning of the internal position of the solid sample.

(1.2)Product principle

The structure of the plasma cleaner is mainly divided into five major components: control system, Excitation power system, vacuum chamber, process gas system, and vacuum pump system.
