Led Display Low Temperature Resistant - Conformal Coating
In last knowledge page, we have introduced the attention on the power supply and warm air curtain parts, to let the whole led display screen system low temperature resistant. And in this knowledge page, we will introduce further about the conformal coating process to the power supply and PCB.
The outdoor electronic led displays run long period under the open air environment, so the high-low temperature resistant, waterproof, anti-corrosion is necessary to the PCB, power supply, and solder joints etc. To achieve that, we adopt the conformal coating to all those components. The PCB conformal coating is a special mixture, to protect the components on the PCB and prevent the ingress from the environment. In this way, the led screen equipment's life time would be longer, as well, it would work more stable and reliable.
The conformal coating is painted onto the surface of the PCB, and form a light, thin and flexible film with the depth of only 25-50 micrometer. It would be capable to protect the circuit from the damage under the environment of vibration, humidity, salt, moisture, high temperature, low temperature, and the chemical material environment.
Without the conformal coating painted, the PCB is possible to have the problems such as corrosion, become mildewed, and short circuit, this kind mulfunction would do big harm to the electronic equipments.
To led display system, we should pay the special attention because the running time is very long, the working environment is not good, and the components are many. So to ensure the reliability of the led display screen, we make the strict quality control on the process of painting the conformal coating.

Actually in this page, we introduce much about the conformal coating. It seems not much related with the low temperature resistant. But actually it's one factor that need to pay attention to. For example when the temperature get low from the high temperature, the low temperature will allow more water to freeze, from the air...
We feel happy as well to share some idea about the conformal coating on LED display screen, and other electronic equipments.
In next knowledge pay, we will continuously introduce more points about the low temperature resistant of led display.
