LCD liquid crystal screen PCB board heat dissipation reasons and solutions
Oct 17, 2022| The direct cause of the temperature rise of the PCB is due to the existence of circuit power dissipation devices, electronic devices have power consumption to varying degrees, and the heating intensity varies with the power consumption.
When analyzing the PCB thermal power consumption of the LCD liquid crystal display, it is generally analyzed from the following aspects.
1. Electrical power consumption:
(1) Analyze the power consumption per unit area
(2) Analyze the distribution of power consumption on the PCB board
2. The structure of the PCB board:
(1) The size of the PCB board
(2) Material of PCB board
3. Installation method of PCB board:
(1) Installation method (such as vertical installation, horizontal installation)
(2) Sealing condition and distance from the casing
