PCBA Tech - ​Is the nano coating of electronic pcba products worth doing?

Is it necessary for electronics manufacturers to apply nano-coating to the PCB of the product? Sometimes it is passive, such as PCB processing, customers have product waterproof requirements, and then the engineers show their magical powers, and they have been busy choosing PCB nano coatings among many waterproof glues and waterproof paints. There are many reasons, such as nano coatings. The layer just solves a problem that has not been solved since the agreement, or if you want a quick-drying and ultra-thin protective coating, you can't understand those thick nano-layers that have to wait a day to dry. Another situation is that it is mostly seen in independent brand manufacturers, who have the autonomy to make products waterproof. Most of them depend on the product strategy or profit. The saving of a dime is a dime.

Whether the value of nano-coating is worth doing, you should think about it from the following aspects. If you are a manufacturing product manager or quality manager, you can use it as a reference.

1. Whether nano coating can improve product quality

Nano-coating protects the product from the PCB level. Assuming that there is no such protection, once water or sweat enters the product, it may kill the product directly, but with the protection of the nano-water-proof coating, from the most conservative theoretical point of view At least the user has enough time for emergency treatment after the water is sprayed, such as opening the shell, blowing dry, etc., which is equivalent to having a first aid time window.

2. Increase sales highlights

If consumers are allowed to choose at the same price or different configurations of the same model, products with waterproof, moisture-proof and corrosion-resistant products will be more bright. Take mobile phones as an example, you can launch a regular version and a waterproof version of a certain model. Of course, the waterproof version will definitely be slightly more expensive. High, as long as the “high” is reasonable, it’s acceptable. Don’t forget that the consumption power of the Chinese people nowadays. The models of the same price in the same industry also have bright spots. Choosing the waterproof product among the products in the same price range has become a key factor in the transaction.

3. Reduce after-sales costs

The use of nano-coating to protect the PCB board will effectively reduce the number of after-sales products and greatly reduce the after-sales cost. According to the true feedback of customers, the original after-sales rate after the use of nano-coating has been reduced from a percentage to ten thousand points. It is conceivable that the after-sales cost It has saved a lot of money and saved profits. A well-known mobile phone manufacturer once said that for every after-sales service of a mobile phone, the cost can swallow up the sales profit of seven mobile phones.

4. Create a good reputation and enhance brand competitiveness

Nano-coating effectively improves the durability of the product, prolongs the service life, and reduces the repair rate. All this naturally helps the company establish a good reputation and enhance the competitiveness of the brand. The establishment of a brand effect is more than just spending two dollars. It can be established by the hype of media advertising. Only by providing high-quality products and services for many years can it leave a good impression in the minds of consumers. Once the impression of such a good product and brand is formed, it will bring unlimited opportunities for the enterprise. The vitality, unless you have never intended to make a hammer sale.

5. Nowadays, the standard configuration of smart wearable products is more in line with the future trend

The current Internet+, cloud services, and big data are prevalent, and many smart wearable products have been born. Coupled with the vigorous development of APP applications, fashionable smart products have become the mainstream, mainly including bracelets, watches, glasses, and virtual reality/augmented reality. Several types of products are the main products, and these carry-on products are very susceptible to water vapor and sweat and other substances. If the PCBA of these products is protected by nano-coating, the products can be effectively protected and more accidents can be prevented. From the perspective of future development trends, the manufacturing industry is bound to be highly integrated, and product components will be smaller, more microscopic, and more sophisticated. For the future ultra-large-scale integrated PCBA, the destructive power of a drop of water must not be underestimated. From the perspective of social development In other words, consumers will pay more and more attention to product quality, and the destruction of copycat mobile phones can explain this problem. Therefore, nano-coating is in line with the general trend from the perspective of improving product quality.

6. The cost of adding nano-coating materials and other processes in the PCB processing and production process is not too high

As a new type of material, nano-coating, many manufacturers are worried that the cost of using such a coating will increase significantly. According to the statistics of practitioners, if nano-coating is used, taking the Bluetooth sports headset PCB as an example, the single cost is about 0.3 -0.5RMB. In some cases where other coating materials are used for coating with machines, the cost of outsourcing and processing one is about 0.4-0.5 USD. In terms of cost, the increased cost of fashion digital products is basically within an acceptable range.

In general, under the rapid development of modern technology, the use of nano-coating in electronics has increasingly highlighted the importance of its use. Nanomaterials are still in their infancy. PCBA manufacturers should consider more about the benefits and reductions that the use of nano-coating can bring to electronic products, and whether it is worth the maximum use within a controllable range.
