Electronic devices have undergone a revolution in size, performance and portability. From consumer devices like smartphones, tablets and wearables to specialised industrial technology such as automation controls, electronics are everywhere — including in many challenging environments. Without adequate electronic protection, components inside devices can suffer corrosion when exposed to contaminants. This degrades electronic performance and may lead to electrical shorts and device failure. At the same time, smaller, more complex, dense printed circuit boards (PCBs) with high-performance components, LEDs and a variety of miniaturised components are placing higher demands on protective coatings.
3M™ Novec™ Electronic Grade Coatings offer protection against corrosion for the sensitive internal components of devices and are ultra-thin compared with traditional conformal coating options. Our products are the result of decades of experience improving electronic grade coatings to help guard against moisture, water/salt water immersion, sulfur, oils, humidity and pollution. These offer ease of application, reworkability and the ability to apply without masking or curing.
When you choose Novec coatings, you gain all the advantages of 3M’s innovative materials, deep knowledge base and dedicated support. Here’s a look at some of the key benefits of these high-performance coatings:
Novec electronic grade coatings have been proven effective against corrosion through extensive testing, as seen in these images showing untreated and treated circuitry that has been exposed to salt fog. They act as an excellent circuit board protective coating, providing a uniform oleophobic and hydrophobic layer that helps cover surfaces of a component for exceptional repellency of moisture, oils, dirt, grime, fingerprints and other environmental contaminants. Novec coatings help provide excellent protection and resistance against corrosive agents that devices might encounter, including:
Ultra-thin Novec coatings can be alternatives to traditional conformal coatings and a smart choice for your business. In a dip application, thicknesses can range from 0.1 to 1.3 microns, or 1 to 6 microns. In a typical single-pass spray, thicknesses range from 1 to 6 microns; layers can be built up to create appropriate thicknesses. This compares to up to 25 microns or more for typical conformal coatings. Thinness has several advantages, including:
3M Novec Electronic Grade Coatings can save costs and increase efficiency without compromising performance.
Performance without compromise means choosing products that don’t put workers or the environment at risk. Novec electronic grade coatings are formulated with 3M™ Novec™ Engineered Fluids, which offer:
3M Novec Electronic Grade Coatings for device component protection are the result of decades of development and evolution by 3M experts. Their careful and precise development can be seen in their exceptional properties, which also make these products versatile for novel applications such as an oil barrier or filter.
