PCBA conformal paint and UVLED curingread count [450] release time：2022-08-24 09:20:00

PCBA is the abbreviation of Printed Circuit Board Assembly, that is, circuit board + component assembly, which is a finished board. Three-proof paint is a kind of coating used to protect circuit boards and related components from environmental erosion. After the three-proof paint is cured, a protective film will be formed. The protective film has properties such as insulation, moisture-proof, leakage-proof, shock-proof, dust-proof, anti-corrosion, anti-aging, and corona resistance.

There are generally three curing methods for conformal coatings, namely moisture curing, heat curing and ultraviolet curing. For example, the tack drying time of polyurethane conformal paint at room temperature is approximately About 30 minutes, complete drying time is 24-48 hours； Curing by heating curing method also takes about 2-3 hours to completely dry. ； With UVLED curing, it usually dries within a few minutes, and UVLED is a cold light source, which only heats up the surface of the irradiated object in 5 seconds. °C left and right, causing no thermal damage to electronic components. It is the fastest curing method among the three curing methods, which greatly improves production efficiency.

With the popularization of automation, many manufacturers have begun to use automated equipment for production. PCBA can be sprayed with conformal protective paint through automated equipment. After spraying, it can be cured through an online curing machine, which greatly speeds up production. Shenzhen Yongcheng has rich experience in the R&D and production of PCBA conformal paint curing equipment. Currently, it has a variety of PCBA online curing machines, which can not only be used alone, but can also be equipped with assembly lines for linked production. In addition to the existing models of online curing machines, they can also be customized according to the actual needs of customers to truly solve their needs.
