Conformal Coating Subtronics Assembly Corporation, offers Conformal Coating to protect your electronic printed circuit boards from moisture and contaminants, preventing short circuits and corrosion of conductors and solder joints.  Coating also minimize dendritic growth and the electromigration of metal between conductors.  In addition, the use of conformal coatings protects circuits and components from abrasion and solvents.  Stress relief is also provided, as well as protection of the insulation resistance of the circuit board. Subtronics offers our customers who require conformal coating an economical operation using an automated process on our PVA2000.  We utilize a Humiseal 1C49 material, which provides the best protection from corrosive chemicals to humid environment protection.  Humiseal 1C49 material also helps protect the electrical integrity of the assemblies from vibration.                                                                                                 PVA2000                                                 Subtronics offers a clean, efficient process for applying conformal coatings while                                                 virtually eliminating labor-intensive masking operations by using the PVA2000.                                                  Utilizing a controlled atomized spray and a non-atomized flow coating process,                                                 the PVA limits to a defined, preprogrammed coverage area.  Film builds as low                                                 as .01 mm can be achieved across the desired surface.  The PVA selective                                                 coating process results in greater material utilization with transfer efficiency of                                                 99%, a significant increase over dip, brush or hand spray.                                                                                                 -View/Download: PVA2000 Data sheet (pdf, 445 KB)
