Select the resistor according to the board size:

Sensitive resistor common sense:

a, thermistor:

It is a kind of resistor that is extremely sensitive to temperature. It is divided into positive temperature coefficient and negative temperature coefficient resistor. When selecting, pay attention not only to its rated power, maximum working voltage, nominal resistance, but also to the maximum operating temperature and resistance temperature. Coefficients and other parameters, and pay attention to the direction of resistance change. BGA VGA Repair Machine for Laptop Motherboard

b, photosensitive resistor:

A resistor whose resistance changes with the intensity of light. It is divided into a visible light photoresistor, an infrared photo-resistor, and an ultraviolet photo-resistor. When selected, the spectral characteristics of the circuit are first determined. BGA VGA Repair Machine for Laptop Motherboard

c, varistor:

It is a non-linear resistor that is sensitive to voltage changes. When the voltage on the resistor is within the nominal value, the resistance on the resistor is infinite. When the voltage is slightly higher than the nominal voltage, the resistance is very fast. The drop causes the resistor to be in a conducting state, and as the voltage drops below the nominal voltage, its resistance begins to increase again.

The varistor can be divided into non-polar (symmetric) and polar (asymmetric) varistors. When selected, the nominal voltage of the varistor should be the voltage applied across the varistor. -2.5 times, pay attention to the temperature coefficient of the varistor. BGA VGA Repair Machine for Laptop Motherboard

d, humidity sensitive resistor:

It is a resistor that is very sensitive to humidity changes and can be used in various humidity environments. It is a transducer that converts humidity into an electrical signal. It should be selected according to the different characteristics of different types and the accuracy of the humidity sensitive resistor. Humidity coefficient, response speed, humidity range, etc. are selected.

Note: The main characteristic of the resistance at low frequencies is the resistance characteristic, but at high frequencies, not only the resistance characteristics but also the side of the reactance characteristics are radio (especially important in RF circuits).
