Corona Treaters and Plasma Cleaners Specifications

Type

	Technology Type
	Your choices are...
	Air Plasma / Corona		Unlike vacuum equipment, atmospheric plasma treating systems do not use a vacuum chamber and electrodes. Instead, a generator and transformer produce plasma and use air pressure to move the plasma through a nozzle. This type of plasma and corona treatment equipment is often used for component preparation in bonding, painting, soldering, and varnishing applications. Corona discharge at frequencies of 15-to-25 KHZ is most effective because of how the electrons oscillate in the gap between the electrodes. Such electrical surface treatment (EST) systems include a high-frequency generator, high-voltage transformer, and treatment electrodes. The frequency of the generator’s output signal is adjusted automatically, and the range depends on the load impedance. The transformer then steps-up the generator’s output signal to the level needed to generate the discharge. Such plasma treatment equipment and corona treatment equipment also features two electrodes: a treating electrode and a counter electrode.
	Chemical / Gas Plasma		Chemical and gas plasma systems generate plasma by ionizing a specific gas. Gas plasma treatment systems are useful in removing organic surface contamination in applications requiring critical cleaning. Critical cleaning is often required in the biomedical, semiconductor, printed circuit board, flat panel displays, and in optical industries. Specific gases can impart unique properties to a surface such as biocompatibility. For example, ammonia plasma treatment is used to attach amine functional groups to biomedical component surfaces that act as hooks for anticoagulants like heparin.
	Flame		Flames or combustion can be used to generate plasma for surface treatment.
	Microwave Plasma		Plasma or ionized gas is generated by using a microwave chamber, which produces more isotropic plasma for etching and ashing processes.
	RF Plasma (ICP)		Plasma or ionized gas is generated and sustained by inducing current into the gas or plasma using a radio frequency-powered magnetic field. RF plasma systems are also referred to as inductively coupled plasma (ICP) systems. A very high density plasma with directional effects can be attained, which is useful in achieving anisotropic etch profiles.
	Vacuum Plasma		Vacuum plasma treating systems use electrode elements inside a vacuum chamber to produce a high-frequency electrical discharge under low pressure. In some applications, treatment gases such as argon or oxygen are required. Treatment cycle times range from 2-to-120 seconds, and are a function of the surface’s shape and material. Vacuum plasma treating equipment is typically used to treat plastic profiles, containers, molds, and extrusions.
	Specialty / Other		Other unlisted, proprietary and specialized technology.
	Search Logic:		All products with ANY of the selected attributes will be returned as matches. Leaving all boxes unchecked will not limit the search criteria for this question; products with all attribute options will be returned as matches.
	Plasma Etcher / Cleaner?		Plasma etchers, ashers, and cleaners are machines using higher energy plasma to aggressively attack or etch a surface of metal, ceramic, or plastic. Plasma ashing is used to completely remove organic contaminants or polymer layers on a metal, ceramic, or semiconductor surface.
	Search Logic:		"Required" and "Must Not Have" criteria limit returned matches as specified. Products with optional attributes will be returned for either choice.
	Surface Treater / Enhancer?		The equipment can enhance characteristics of a surface by removing organic contaminants, attaching specific functional groups and increasing the surface energy or tension and therefore the wettability, biocompatibility, or bondabilty of the treated substrate.
	Search Logic:		"Required" and "Must Not Have" criteria limit returned matches as specified. Products with optional attributes will be returned for either choice.
	Benchtop / Lab?		Plasma or corona generator is a benchtop or laboratory scale unit suitable for research and development, material evaluations and initial process parameter experiments.
	Search Logic:		"Required" and "Must Not Have" criteria limit returned matches as specified. Products with optional attributes will be returned for either choice.
