PCB Technical - Application of waterproof material on pcb and FPC proofing

Nano waterproofing agent can be understood as nano waterproof coating, nano moisture-proof coating, anti-salt spray corrosion coating from the function, which provides a better solution for the waterproof of electronic products.The nano coating is directly applied to the PCBA of electronic products by immersion and spraying.As long as the PCBA is soaked in the nano solution for a few seconds or sprayed,it can be completely dried after taking it out and drying it at room temperature for a few minutes.Traditional three anti-paint products often take 24 hours to dry and save time.

The construction process of the nano waterproofing agent is spraying or dipping,which is easier to form at one time,the coating is uniform, there is less sagging, no bubbles and skinning phenomenon,component pins and small gaps are completely covered,and The traditional three-proof material process is easy to generate bubbles and uneven conditions, and there are more cases of repeated spraying in some parts. Some plates need to be washed and dried before spraying. The Ubao nano waterproofing agent avoids these situations. This product can be widely used in communication equipment, circuit boards and other fields.

The characteristics of PCBA circuit board nano waterproof material

1.Nano waterproof materials are suitable for all PCBA boards,and have very good binding ability with all substrates, waterproof, sweat, moisture and corrosion.

2.A nano-conjunct film similar to the "lotus leaf effect" can be formed on the PCBA board, which effectively protects the working ability of electronic components in the extreme environment of humidity and underwater,and enhances the ability of electronic components to prevent moisture and corrosion

3.By immersing the PCBA board,the nano waterproof material can penetrate into the tiny gaps of the electrical components,achieve complete coverage and wrapping,and improve the waterproof performance.This situation is suitable for electronics that work under moisture or underwater for a long time.

What are the principles of FPC proofing

1.Based on the principle of high-quality substrate and material selection

The quality of the product itself and the service life of the machine will directly affect the follow-up production effect of this product. In order to ensure the efficient and steady improvement of the fpc proofing level, the fpc proofing merchants with good reputation in China also have higher craftsmanship and more advanced product production. High-quality manufacturing materials improve the level of circuit production, and can ensure the safety and reliability of long-term applications with better integrity.

2.Based on the principles of graphics optimization and performance improvement

It is reported that after the design drawing of the circuit board is determined, it is necessary to ensure that the production schedule and feasibility of this product can be determined and reliable. Fpc proofing must be based on this design drawing to achieve better optimization and processing to ensure that it does not affect the product At the same time, it can reduce the layout of the circuit as much as possible. This optimized design scheme can not only reduce the unit investment cost, but also make the fpc proofing have a better aesthetics. The professional personnel can upgrade the process of the fpc proofing and The improvement of the production method and the use of product testing to correct the data can make this kind of fpc proofing level better guaranteed.
