Accelerated Assemblies, a provider of PCB assembly and manufacturing services, offering prototyping, low- to mid-volume production, testing, inspection, rework, and turnkey assembly solutions, offers PCB conformal coating services to protect printed circuit boards from moisture, dust, chemicals, and temperature fluctuations, helping reduce corrosion, electrical leakage, and short circuits while supporting long-term reliability.
The company provides conformal coating solutions using a range of coating materials selected according to application requirements. These include parylene for uniform vapor-deposited coatings with moisture, chemical, and dielectric protection in aerospace, medical, and military applications; acrylic resin for moisture, dust, fungal resistance, and UV traceability in consumer and industrial electronics; epoxy resin for structural stability, abrasion resistance, and protection against mechanical wear and chemical exposure in heavy-duty industrial environments; silicone for flexibility, thermal stability, and vibration resistance in automotive and outdoor electronics; and polyurethane (urethane) for chemical, moisture, and mechanical protection in automotive, industrial, and military applications.
Accelerated Assemblies' PCB conformal coating services include coating material selection based on environmental and operational requirements, surface inspection and preparation through cleaning, surface activation, and plasma treatment, and multiple coating application methods including spray coating for large-scale production, dip coating for complex geometries, and brush coating for touchups and small production batches.
The company also performs curing and drying using heat, UV light, or air drying to achieve the required coating properties. Post-application inspection includes visual inspection, coating thickness measurement, adhesion testing, and electrical testing to verify coating quality and ensure PCB functionality. Rework and repair services are also available, allowing existing coatings to be removed and reapplied following component replacement or contamination.
According to the company, PCB conformal coatings improve durability by protecting boards from environmental exposure, enhance electrical performance by reducing corrosion and leakage, provide additional resistance to vibration and shock, improve thermal stability in demanding temperature conditions, and help prevent corrosion of metal components.
Accelerated Assemblies states that its PCB conformal coating services support applications across automotive, lighting, military and defense, consumer electronics, and telecommunications, where environmental protection and long-term PCB reliability are required.
