PCBA Tech - PCBA specific matters and its characteristics

Introduction of PCBA circuit board and its characteristics

With the continuous development of electronic technology and people continue to pursue more convenient enjoyment, mobile phones are constantly innovating to provide people with novel services. However, some seemingly basic technologies, such as battery life, enclosure protection, etc. For example, the water resistance of mobile phones, this feature often only appears on some specific models. So people want to crack, develop, modify, etc. to change this situation.

More and more high-end manufacturing industries are aware of this, and continue to invest in R&D and innovation to improve quality, and begin to find and use more cutting-edge materials and technologies. Nano-moisture-proof and anti-corrosion coatings are electronic products PCB waterproof and moisture-proof and salt-proof. The advanced representative of fog corrosion materials, nano-coating not only has the basic protective characteristics of three-proof paint, but also solves some problems that cannot be solved by three-proof paint, and greatly improves the protection and environmental protection performance.

Dynamic display of super-hydrophobic effect on PCB surface

Nano coatings are getting more and more attention from some users, because they have better heat dissipation and lighter weight than traditional waterproof, moisture-proof and salt-spray products. Especially when applied on PCBA, the construction is simple, no additional equipment is required, and no additional processes are required., And does not affect the conductivity of the connector, it has been used in other companies' products.

Features of PCB Waterproof Coating for Bluetooth Sports Headphones

Bluetooth headset PCB waterproof coating is a colorless, transparent, non-toxic and harmless, halogen-free, non-destructive ozone, non-flammable, moisture-proof, moisture-proof, anti-corrosion, and anti-mildew liquid nano coating. It meets EU environmental protection standards. RoHS, REACH testing and certification, resistance to salt spray, sweat erosion, resistance to flux residues, organic matter remaining after manual contact on the production line, residues from the circuit board manufacturing process and other substances that damage the PCB.

The characteristics of PCBA circuit board nano coating

1. Nano waterproof material has very good bonding ability with various substrate PCBA boards, waterproof, sweat, moisture and corrosion.

2. Form a nano-conjunctival film with very good hydrophobic effect on the surface of PCBA circuit board to form a lotus leaf effect, which can form a strong protective layer on the surface of electronic components to prevent electronic products PCBA circuit boards from wading and damp. Corrosion by acid, alkali and salt.

3. It can penetrate into the tiny gaps of electronic components through the immersion construction method to achieve complete coverage and wrapping, and the product will get a comprehensive three-dimensional waterproof effect.

4. Multi-series and multi-concentration products are suitable for different applications. The suitable series can be selected according to your specific requirements for quality, and the selection can be made after sample testing.

5. The waterproof material is more environmentally friendly, the formed coating is invisible to the naked eye, and the heat dissipation performance is very good. The connector does not need to be protected before soaking, and the electrical conductivity is not affected.

Things the PCBA industry must know

With the rapid development of science and technology, the iterative speed of electronic technology products is changing exponentially. Any outlet may be fleeting. For a product, there is often not much time for trial and error. The solution is to choose a factory or several factories for PCBA proofing after the design is completed and before mass production. Some people will ask why this is necessary? What is the purpose?

1. Check whether there is any problem with the PCBA design process and whether there is any need to modify it, because only through actual testing can we find some unseen problems on paper, and put an end to paper talk.

2. Screening strong factories can ensure the yield rate and test pass rate of PCBA production, have an assessment of the approximate delivery time and quality, and have an accurate estimate of the various conditions of the later large-scale orders.

Why choose PCBA for labor and materials?

There are generally two processing methods in current electronics manufacturing, namely processing with supplied materials and contracting with materials. Processing with supplied materials means that the customer provides materials, and the factory provides SMT chip processing and DIP plug-in processing, etc. The contracting of labor and materials means the customer Provide a full set of information, the factory is responsible for purchasing, production, etc. Faced with these two production and processing methods, more and more customers choose the latter-contract labor and materials, why is this?

More and more people choose PCBA for labor and materials mainly for the following reasons:

1. Let professional people do professional things

The electronics manufacturing factory has a complete departmental system, clear division of labor, rich experience, multiple procurement channels, and reduced handling links, which helps shorten the delivery time.

2. Cost saving

The processing method of contract labor and materials can greatly reduce the labor cost, time cost and material cost of the customer.
