printed circuit board assembly Foreign Trade: You Need to Know These "Ten Don'ts"
The following is an introduction to the functional characteristics and related knowledge of circuit boards. As a foreign trader of printed circuit board assembly, you need to know these "ten don'ts".
"The functional characteristics of the circuit board and some Nixie tube will be shown in the following figure only when consuming the light power timing, and the circuit board will work only when the voltage source is input, so we must know that if we want to have a function, many people will have no end when asking, then we need to know how to understand this function first, but there are also some circuit board functional characteristics and what it is.
The following devices are used for the POWER unit, including an output voltage of 24 V=20 V.
The input voltage range is 30 V~25 V, and the output voltage range is 0~18 V.
● LYG1 0 ~ 30 ms,1 ~ 2 ms,3 ms,5 ms,6 ms。
Highlight: 1 JOI01 intelligent audio machine, supporting 8-channel regulation, the control mode is 8-channel universal input (level, harmonic, open wave), the reference instrument has 12 bit ADC (voltmeter, ammeter, digital), supporting one PWM (transistor input), and the other can send commands through remote control. The signal undergoes 2M integration, and the amplitude of the received input signal varies exponentially. The size of the output signal is a voltage signal, which is expressed in pF and has an amplitude of λ。
Pulse signal: Used for converting audio signals into signals, usually driven by DC or AC methods.
The applied voltage of the Nixie tube is connected to the Nixie tube. The common point of the triode is used to make the base voltage of the triode higher. Generally, the collector of the triode can only be seen on the MCU if there are few IO pins.
As a counting screen, the Nixie tube can be used to control the light with corresponding value by the triode. When the Nixie tube is powered on, the triode is triggered. Since the base current of the triode cannot be driven, the trigger circuit is disconnected, and the light will not be on. If a multimeter is used to detect the collector and emitter of a transistor, the cutoff state variable of the transistor can also be used for comparison. If it is more troublesome, the performance of the transistor can be restored.
