PT-5S
vacuum plasma cleaning machine: plasma is usually called the fourth
state of the material, the first three states are solid, liquid, gas,
they are more common, it exists around us. Plasma is only present in the earth in a particular environment, such as lightning, aurora. It is as if the energy is needed to convert the solid into the gas, and the energy is needed to produce the ions. A
certain amount of ions is composed of charged particles and neutral
particles (including atoms, ions and free particles) mixed composition. The ion can be conductive.
Application of Plasma Technology
Through
the surface of the object of the plasma bombardment, can achieve the
surface of the object etching, activation, cleaning and other purposes. Can
be significantly enhanced the adhesion of these surfaces and welding
strength, plasma surface treatment system is now used in LCD, LED, IC,
PCB, SMT, BGA, lead frame, flat panel display cleaning and etching. Plasma-cleaned ICs can significantly improve wire bond strength and reduce the possibility of circuit failure. Residual
photoreceptors, resins, solution residues and other organic
contaminants are exposed to the plasma zone and can be removed in a
short period of time. The PCB manufacturer uses a plasma etch system to perform decontamination and etching to remove the insulators in the borehole. For many products, whether they are applied to industry. Electronics, aviation, health and other industries, reliability depends on the bonding strength between the two surfaces. Regardless
of whether the surface is a metal, a ceramic, a polymer, a plastic, or a
compound therein, the plasma has the potential to improve the adhesion
and improve the quality of the final product. The ability of the plasma to change any surface is safe, environmentally friendly and economical. It is a viable solution to the challenges faced by many industries.
The principle of plasma treatment
A
group of electrodes through the RF power supply, the formation of
high-frequency alternating electric field between the electrodes, the
region of gas in the alternating electric field under the agitation, the
formation of plasma, active plasma on the surface of the physical
bombardment and chemical reaction double role, The surface of the cleaning material into particles and gaseous
substances, after the vacuum discharge, and to achieve the purpose of
surface treatment.
In
the whole plasma treatment process, the factors that affect the plasma
treatment effect include process temperature, RF power, gas
distribution, vacuum, electrode setting, electrostatic protection and so
on.
