Analysis of curing time of conformal coating on circuit board

YaoNeng silicone conformal coating and acrylic conformal coating in general at room temperature (25 degrees) dry time is about 10 to 30 minutes, after the table dry can be carried out the next production process, the complete curing time of conformal coating is 24 to 48 hours, this time conformal coating has been completely dry on the circuit board. If you need to test mechanical and electrical performance is best after 72 hours, then the test results are more accurate and objective. If the heating curing is generally 60-80 degrees heating for about 30 minutes, and then the circuit board is taken out after the natural cooling, completely dry setting time of about 2 hours, heating curing can greatly improve the production efficiency.

The surface dry time of polyurethane conformal coating at room temperature is about 30 minutes, and the complete dry setting time is 24 to 48 hours. It can also be cured by heating and curing, heated to 60 degrees after baking for 30 minutes, and completely dry and solid for about 2 hours.

UV conformal coating can be cured by UV light equipment, dry time can be dry in a few minutes, is all conformal coating among the fastest curing speed. However, some places on the circuit board that cannot be irradiated by UV light need to be naturally cured by moisture. In this case, curing still needs a longer time.

Shenzhen Yaoneng Technology Co., Ltd. specializes in the production and sales of various kinds of circuit board conformal coating, and to solve the various problems of conformal coating products and use for customers, to provide a full range of conformal coating solutions.
