Wilson Process Systems (WPS) is offering greater levels of environmental protection for systems that are increasingly being used outdoors. Initially purchased to ensure cost-effective, high-quality conformal coating of PCBs destined for use in the outdoor-illuminated-signage industry, WPS' two fully-automated Assymtek conformal-coating machines are said to be the fastest, most accurate systems on the market.
Fan-width control automatically adjusts to allow for variations in the viscosity of the coating, which is applied to Mil spec thicknesses using a non-atomising process. This ensures that the coating only covers the required board parts, without any requirement for masking. The automated process is suitable for acrylic coatings, such as Humiseal's 1R32A-2. WPS can also offer aqueous coatings.
