Electronic products are often used in humid or demanding environments. Nano waterproof coating helps protect PCBA modules from water, sweat, oil and contamination without adding large enclosures or heavy materials.
How Nano Coating Protects PCBA
Nano coating forms a thin protective layer on the surface of a printed circuit board assembly. The coating can cover exposed circuits and component surfaces, reducing the risk of short circuits and corrosion caused by moisture and contamination.
What IPX7 Means
IPX7 is a water ingress protection rating. A product or module rated IPX7 can withstand temporary immersion in water under defined test conditions. For consumer electronics such as TWS earbuds and portable speakers, IPX7 protection supports durability in real-world use.
Protection Beyond Water
A good nano coating can also provide resistance to acid, alkali, oil, salt and dirt. This helps protect PCBA modules in products used outdoors, during exercise or in industrial environments.
Applications for Nano Coating
Nano waterproof coating is useful for TWS earbuds, Bluetooth speakers, smart wearables, communication devices and other compact electronic products where space is limited and environmental protection is required.
