Indoor appliances will also be struck by lightning.
Last Sunday, Beijing ushered in the biggest rainstorm this year. It was reported that two people were suspected of being killed by lightning. Beijing almost thunderstorms last week, and it is said that this week is no exception. In fact, the thunderstorms are not the same in Beijing. Most of the country has been hit by thunderstorms and winds. In the season when lightning strikes often, it seems that it is not safe to hide in the house. Everywhere there is a report that the electrical appliances in the home are struck by lightning. How to ensure its safety?

Thick Copper PCB are used extensively in power electronic devices and power supply systems. A growing trend in the PCB industry, this unique type of Heavy Copper PCB features a finished copper weight of more than 4oz (140μm), compared to the 1oz (35μm) or 2oz (0μm) copper weight generally found in those with a Standard PCB copper thickness.
The additional copper PCB thickness enables the board to conduct a higher current, achieve good thermal distribution and implement complex switches in a limited space. Other advantages include increased mechanical strength at connector sites, the ability to create a smaller product size by incorporating multiple weights on the same layer of circuitry and the ability to use exotic materials to their maximum capacity with minimal risk of circuit failure.
