Precision Cleaning For New Parts

Persys performs precision cleaning for new parts prior to their use in the semiconductor, magnetic, solar, optics, and aerospace industries, where even a microscopic contaminant can impact the overall quality of the equipment and product.

We tailor the process to meet the stringent specs of every customer, allowing them to better manage planning and procurement.

Persys uses cutting-edge cleaning techniques to remove unseen contaminant particles such as metals, organics, fibers, and residues and validates cleanliness on a microscopic level.

We then package the parts in cleanrooms for easy, on-site assembly.

Methods

CO2 cleaning

CO2 cleaning is a non-abrasive, residue-free, and environmentally friendly cleaning method, generally used in final cleaning or for fragile surfaces that are sensitive to water. In this process, liquid or gaseous carbon dioxide is nucleated into small, dry ice particles. When the dry ice comes into contact with a surface, it removes particles of all sizes by momentum transfer or using a transient solvent or a freeze-fracture mechanism. Nucleation also creates a high-velocity carrier gas stream that blows contaminants away.

Ultrasonic cleaning (water + solvents)

Ultrasonic cleaning is an ideal solution for complex parts with threads, rough surfaces, or blind interior spots that are inaccessible with other methods. The technique uses high-frequency sound waves to agitate an aqueous, semi-aqueous, or solvent-based cleaning solution and dislodge particles, removing contaminants at a microscopic level. Higher sound frequencies are used to remove finer particles.

Disassembly / Assembly

New and used parts and tools often need to be disassembled before decontamination and cleaning and then reassembled and packaged for use. The processes must be conducted carefully, in the right conditions, to prevent harm to the part and deliver it ready for use without the need for any additional treatment.

HUV Ready Cleaning

A particular unique method to clean new parts from Organic materials.
This technology will reduce the pump-down time in the tool and save you time and money. Our system will outgas your parts to meet your specifications and up to 1X10^-9 torr or meet the ASTM E-595-15 standard.

Passivation

Passivation Improving the corrosion resistance of stainless steel parts by removing ferrous contaminants like free iron from their surface, restoring them to their original corrosion specifications.
We follow the ASTM A380 standard for Passivation.
