If you are at home, you can choose to turn off the power first and then rotate the fan blades. How to choose a rigid-flex board company. Below, we will introduce the advantages of several rigid-flex board companies.
Typical flexible circuit board substrate: FR4 (based on PI), with reinforcement of the cover layer, one side reinforcement and the other side reinforcement. The reinforcement is etched on one side of the FPC. FPC is a flexible circuit board, and its most common form is polyimide (PI).
The material of a rigid PCB is generally an insulation film or conductor board made by pressing epoxy resin (glass fiber) and copper foil (copper foil), and then welded from a tinned or tinned insulation substrate and wires.
The material of rigid PCB is generally polyimide or polyester film (polyester film or polyester film). Due to the interconnection structure of both, the resistive wire itself is a resistor. If there is no insulation layer, a coupling channel will be formed between the wires. If there is an insulation layer, a resistance network with high resistance to the conductor will be formed between the wires, called conductor resistance. (Refer to 100M Ω.
The power and ground wires of any electrical appliance require a low impedance system, so there are many parasitic components on the working power lines. So what are the parasitic components on the power line.
The impact of power supply interference on ground is significant. To monitor whether the resistance meets the indicator requirements, it is necessary to use circuit control and protection resistance for monitoring. Therefore, the following points should be noted.
Why should a combined grounding plane be designed for a power circuit first? Due to the small resistance of the combined grounding plane, it is usually used for signal transmission. Therefore, signal transmission is a very important task. This technology can eliminate many interference from ground operation and quickly achieve a "well to ground" connection. Therefore, by protecting various types of equipment, the durability between them is improved.
Another feature is adaptive mode. It can automatically generate a full duplex protection scheme based on various connection methods required for implementation. In addition to overvoltage protection and terminal bonding, it can also achieve various forms of protection such as self isolation processing, thereby minimizing the safety of high electronic protection final products.
It is precisely the systems of these components that can play a good role in bringing the original product innovation to a certain limit. In addition, isolation can be implemented as needed during product operation to prevent performance failures caused by interference.
Ultra wideband can be compatible with various types of signal inputs, serving as multiple configuration signals for input protection circuit breakers, circuit breaker protection circuit breakers, etc.

● The isolation transformer can form the main control system with equipment, control system, PLC, various servers, frequency converters, industrial control, electronic testing equipment, etc.
