PCBA Waterproof Nano Coating Forms An Invisible Protective Shield After 3 Seconds Of Immersion, Protecting The Circuit Board From Water

In today's era of increasingly sophisticated and miniaturized electronic devices, 

effectively protecting PCBA boards from moisture, salt spray, condensation,

 and other forms of corrosion has become a core challenge for manufacturers aiming to enhance product reliability.

 Traditional protective processes such as vacuum coating and parylene coating generally face issues like high costs, complex procedures, 

and difficulty in maintenance.  leveraging its independently developed PCBA waterproof nano-coating technology, 

has broken through the limitations of traditional processes and is redefining the standards for circuit board protection!

Jie'an Nano PCBA Waterproof Nano-Coating is a revolutionary protective solution specifically designed for high-density, high-complexity circuit boards. 

It only requires immersing the PCBA board, precision electronic components, and connectors for 3 seconds, 

then air-drying at room temperature for 3 minutes to complete curing. There is no need for a vacuum environment or high-temperature baking, quickly forming an ultra-thin,

 dense, transparent protective layer of only 1-3 μm on the substrate surface.

This nano-coating is almost invisible to the naked eye, yet it achieves IPX7-level waterproofing (fully functional after 30 minutes of submersion in 1 meter of water), 

passes a 96-hour neutral salt spray test without any signs of corrosion, and effectively suppresses condensation formation through its nano-microstructure design, 

preventing circuit board short-circuit failures at the source. At the same time, 

the coating does not affect component heat dissipation or signal transmission, perfectly meeting the protective needs of precision electronic equipment.

Waterproof and Condensation-Resistant: IPX7 waterproof rating, capable of withstanding short-term immersion. 

Nano-scale hydrophobic structure prevents condensation adhesion, addressing short-circuit risks in high-humidity environments.

Outstanding Corrosion Resistance: No corrosion after 96 hours of neutral salt spray testing, 

far exceeding the 48-hour protection limit of traditional conformal coatings, able to resist acid, alkali, and industrial dust erosion.

Wide Temperature Stability: Tolerates temperatures from -40℃ to 150℃, does not become brittle in low temperatures or decompose in high heat, 

suitable for complex conditions such as new energy vehicles and outdoor equipment.

3-Second Soak and 3-Minute Cure: No need for expensive vacuum equipment or high-temperature baking,

 significantly shortening production cycles and suitable for large-scale assembly line operations.

Direct Soldering Repair: The coating does not affect subsequent soldering or SMT processes. 

Repairs do not require complete removal of the coating and can be done with quick re-soldering, improving maintenance efficiency by over 80%.

Coating Easily Removable: If component replacement is needed, the coating can be easily peeled off. 

Compared with Parylene's "non-maintainable" or vacuum coating's "expensive to repair" issues, it greatly reduces after-sales costs.

No signal interference: Does not affect WiFi, Bluetooth, RF, or other signal transmissions;

 the impact on heat dissipation is negligible, making it especially suitable for wearable devices, smartphones, and other slim devices

High transparency: The transparent coating does not alter the product's appearance and is suitable for components that require aesthetic appeal, 

such as display panels and precision connectors

Compatible with multiple substrates: Perfectly adheres to various materials such as PCB, 

metal, and plastic, with strong adhesion and low risk of peeling

Certified by authoritative bodies: Complies with international environmental certifications such as RoHS and REACH, 

meeting compliance requirements for exports to the EU, North America, and other markets

Jian Nano PCBA waterproof nano-coating technology has been validated across multiple industries and has become the preferred protection solution in consumer electronics, 

automotive electronics, industrial equipment, and other fields. It has established long-term cooperative relationships with leading companies such as Huawei, Xiaomi, and BYD:

Smartwatches, TWS earphones, electric toothbrushes, and other wearable devices: resist damage from sweat and moisture, reduce product repair rate by 90%,

 and help electric toothbrushes achieve a lifespan of over 10 years.

In-vehicle control units, BMS battery management systems: maintain stable operation under high temperature, high humidity, and salt spray conditions, 

extend the lifespan of BMS modules threefold, and reduce the risk of vehicle failures.

Communication base stations, industrial control motherboards, outdoor surveillance devices: provide long-term reliable protection, suitable for harsh environments 

such as high altitudes and coastal salt spray, reducing field equipment maintenance costs.

COF driver boards, precision connectors: effectively inhibit electrochemical migration, prevent display malfunctions, 

and extend the lifespan of displays and high-end home appliances.

As a national high-tech enterprise, Gean Nano has, since its establishment, focused on the goal of "solving the bottleneck issues in high-end protective materials."

It has gained market recognition through its strong capabilities:

1. Strong R&D strength: Possesses independently developed nano-material formulas and proprietary construction processes, with over 20 core patents obtained. 

The core products have an import substitution rate of over 60%, breaking the monopoly of foreign technology.

2. Comprehensive quality control system: Certified by the ISO9001 international quality management system, 

Gean Nano has established a full-process quality control chain from R&D to production, ensuring consistent performance for every batch of products.

4. Full-process service support: Provides a nationwide technical service network, 

offering one-stop solutions from product selection and construction guidance to after-sales maintenance, quickly responding to customer needs.

With the rapid development of industries such as 5G, the Internet of Things, and new energy vehicles,

 the demand for protective performance in electronic devices continues to rise. 

Jetnano focuses on technological innovation as its core driving force and has formulated five major development strategies:

Product Diversification: Develop specialized nano-coating formulas to cover high-end sectors such as aerospace and biomedical, 

and create multifunctional coatings with anti-corrosion, conductive, and thermal conductive properties.

Continuous Technological Breakthroughs: Increase R&D investment, deepen industry-academia-research collaboration, 

optimize material performance and construction processes, and build higher technological barriers.

Build an Industrial Ecosystem: Establish strategic alliances with upstream and downstream enterprises and research institutions to promote the 

application of nano-protection technology in more emerging fields.

"Domestic high-end manufacturing should not rely on imported protective materials in the long term. 

What we need to do is use our independent innovation technology to build a solid 'protective shield' for China's intelligent manufacturing," said Li Chao, 

General Manager of Jetnano. The company consistently adheres to empowering industrial upgrading through technological innovation, making protective technology 'invisible yet powerful.'
