How to connect 220V voltage to the circuit board
And soft and hard combination plate (reechas, Soft and hard combination plate) -FPC and PCB birth and development, gave birth to a soft and hard combination of this new product. Therefore, the soft and hard bonding board, that is, flexible circuit boards and rigid circuit boards, after pressing and other processes, according to the relevant process requirements together to form a FPC characteristics and PCB characteristics of the circuit board
board or printed circuit board, the English name for (Printed Circuit Board) PCB, (Flexible Printed Circuit board) FPC circuit board [1] (FPC circuit board, also known as flexible circuit board flexible circuit board is poly Imide or polyester film made of a substrate with a high degree of reliability, excellent flexible printed circuit board with a high wiring density, light weight, thin thickness, good bending characteristics!) And soft and hard combination plate
Circuit board name: circuit boards, PCB board, aluminum plate, high frequency board, thick copper plate, impedance board, PCB, ultra-thin circuit boards, ultra-thin circuit boards, printing (copper etching technology) circuit boards. The circuit board makes the circuit miniaturized and intuitive, which plays an important role in the mass production and optimization of the fixed circuit. Circuit board can be called printed circuit
international unit system for the volts (V, referred to as volts), commonly used units are millivolt (mV), microvolts (μV), kV (kV) and so on. This concept is similar to the "water pressure" caused by the water level. It should be noted that the term "voltage" is generally used only in circuits, and "potential difference" and "potential difference" are commonly used in all electrical phenomena.
Voltage, also known as the potential difference or potential difference, is a measure of the unit charge in the electrostatic field due to different potential energy generated by the physical difference. Its size is equal to the unit positive charge due to the electric field force from the A point to point B work done, the direction of the voltage specified from the high potential point to the direction of low potential. Voltage of the
