The substrate of printed circuit board model is made of the best epoxy resin in the industry. 
The welding surface is treated with air-dried insulating paint, which is waterproof and moisture-proof to ensure normal operation under harsh working conditions. 
Shielded enclosure to prevent interference. The Structure
is reasonable and safe.
