UV conformal coating
UV conformal coating is applied to circuit boards and other products. After curing, a coating protective film is formed, which can protect the circuit board and its related electronic components from environmental erosion, and improve the normal operation and stability of the circuit board and related electronic components. performance and service life. However, if the application is not standardized, the performance of the UV conformal coating will be greatly reduced, especially some small details, which need special attention when sizing.
As a UV glue manufacturer, the 5001 series of UV moisture dual-curing conformal coatings produced by AVENTK have been widely used in clients, and have replaced traditional solvent conformal coatings in many clients. Regarding how to obtain better UV conformal coating results, AVENTK recommends that you pay attention to the following points before sizing:
Pay attention to these points before gluing
It is important to finish the PCB board before applying UV conformal coating. If the PCB board is too wet or the board surface is not clean, many small bubbles are likely to appear on the board after the UV conformal coating is used, and some will appear white spots. After this happens, many customers will think that it is the quality problem of the UV conformal coating, but if they spend time and effort to find a better conformal coating, the result will be the same after use.
In fact, if you buy a UV conformal coating (such as AVENTK) produced by a regular and powerful manufacturer, you generally only need to pay attention to the processing process before the conformal coating is applied to solve the problem, and use conformal coating to coat. Before the operation is carried out according to the normal operation method, there will generally be no other problems. Next, AVENTK will introduce you to the normal operation method:
1. The PCB board must be washed with board washing water, and alcohol cannot be used.
2. The cleaned board can be dried in the oven, and the three-proof paint can be applied after the PCB board is completely dry.
3. When spraying or brushing the UV conformal coating, pay attention to the uniformity of the paint surface.
4. The conformal coating of AVENTK is dual-cured by UV moisture. After coating, it is cured by UVLED curing machine, and some gaps can be placed to wait for the secondary curing of moisture. Therefore, after UVLED curing, try to protect the paint surface from damage, so as not to affect the integrity of the paint surface.
