Nicaragua acdc power module potting requirements(2)

Epoxies cannot be used for stress-sensitive and module sealing due to their hardness and are basically eliminated by module power supplies. However, due to its low cost, this epoxy is still used in cost-sensitive micropower supplies. Some domestic bad LED advertising screen power supply manufacturers also use this epoxy resin acdc LED advertising screen power supply module. However, due to stress problems, the failure rate of this LED advertising screen power supply is very high, and buyers are miserable.

The application of module power supply in several aspects
1. Electricity, mainly integrators and meters and smart meters
2. Industrial control, industrial control field
3. Medical, medical equipment, mainly including tire protectors, monitors, etc.
4. Military industry, the military industry is a widely used aspect.

At present, the most commonly used power module is the addition of silicone. This kind of silica gel is generally 1:1, which is easy to operate. When acdc potting power modules, attention should be paid to its thermal conductivity. However, the bonding ability is not very strong, and it can be improved with primer.

Polyurethane has been used in China for a period of time, but due to its high hardness, inconvenient maintenance, and the price reduction of silicone rubber, the cost performance of polyurethane is not high.
