Myanmar 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 Marine boost/buck voltage power supply manufacturers also use this epoxy resin acdc Marine boost/buck voltage power supply module. However, due to stress problems, the failure rate of this Marine boost/buck voltage power supply is very high, and buyers are miserable.
●The design is simple. Power is available with just one power module, with a few discrete components. ● Shorten the development cycle. The module power supply generally has a variety of input and output options. Users can also repeatedly stack or cross stack to form a building block combined power supply to achieve multiple input and output, which greatly reduces the prototype development time.
●Change is flexible. If the product design needs to be changed, simply convert or parallel another suitable power module.
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.
