Ultrasonic Cleaning – This method uses ultrasonic energy (high frequency sound waves) to enhance particle, soil, and grease removal from a surface. Parts are submerged in detergents, deionized water, and/or solvents while subjected to ultrasonication.
Aqueous cleaning – A water-based cleaning using additives such as detergents and surfactants, resulting in environmentally friendly methods of achieving the desired level of cleanliness.
Solvent Cleaning – Various solvents are employed during this precision cleaning step to achieve the desired level of cleanliness.
Pressure Flush Cleaning - Solvents and/or ultra-pure deionized water are sprayed under pressure to further remove contaminants. This method of parts cleaning is most often used in conjunction with ultrasonication in detergents, surfactants, and/or solvents.
Wipe Cleaning – Specialized lint free wipes and swabs, wetted with a solvent or deionized water, are used to hand clean delicate surfaces that cannot withstand more aggressive cleaning methods.
High Pressure Pump Flush Cleaning - A high pressure pump is utilized to clean the interior of small diameter tubes, pipes, and other internal pathways to flush out contaminants. This method is performed with a variety of solvents as well as deionized water.
Cleanliness Verification – Methods of verification within the certified cleanroom can include visually inspecting the parts, microscopically evaluating the parts for the presence of particles, and/or testing for the presence of non-volatile residue on the parts.
