Parylene Deposition Process:
Parylene is applied at room temperature with deposition equipment that controls the coating rate and ultimate thickness. Polymer deposition takes place at the molecular level: Beginning with the granular form of Parylene, raw material Dimer, the material is vaporized under vacuum and heated to a dimeric gas. The gas is then pyrolized to cleave the dimer to its monomeric form. In the room temperature deposition chamber, the monomer gas deposits as a transparent polymer film. The required thickness of a coating can vary based on the application, but thickness can range from the hundreds of angstroms to several mils, with the typical coating being in the microns range.

Parylene (polyparaxylene) is the only solid coating in military standards. It is a new type of conformal coating material developed by Union Carbide in the United States in the mid-1960s. It is a multi-molecule polymer. Parylene is prepared by a unique vacuum vapor deposition process. Active small molecules "grow" a fully conformal polymer film coating of 0.1 to 100 microns on the surface of the substrate. It can be applied to surfaces of various shapes, including sharp edges, cracks and inner surfaces. This film coating has uniform thickness, dense and pinhole-free, transparent and stress-free, does not contain additives, does not damage the workpiece, and has excellent electrical insulation and protection. It can be especially used in areas that liquid coatings cannot cover, such as high-frequency circuits and extremely weak current systems. It is the most effective modern moisture-proof, mildew-proof, anti-corrosion, and salt spray-proof coating material.

Application areas:
Surface mounting technology: high-quality protective layer without air gaps;
Microelectronic semiconductors: high-purity passivation layer and dielectric layer.
Hybrid circuit: Improve the bonding strength of leads and solder joints, eliminate surface moisture; metal ions and other particulate pollution.
Printed circuit boards: They can maintain high reliability in salt spray tests and other harsh environments.
Polymer materials: Their unique physical and chemical properties can be effectively used in the isolation and protection of polymer materials.
Magnetic materials: Their outstanding insulation properties and unparalleled ultra-thin coatings are widely used in the protection of magnetic materials.
Sensors: They are resistant to high temperatures, chemicals, voltages, oil pollution, radiation and other environments.
Medical instruments: They are approved by the US FDA and can be used for various types of in vivo implants to improve the surface lubrication, biocompatibility and reliability of devices.
Cultural relics protection: Parylene can be used to reinforce and protect fragile cultural relics and specimens, extending their lifespan by thousands or even tens of thousands of years.
