Several factors for the increased temperature of printed circuit board and its solutions

The direct factor for the temperature rise of PCB is the existence of power consumption parts and the heat generation intensity varies with the power consumption.There are two phenomena of temperature rise.1.Sectional temperature rise or full -area temperature rise;2. Short-term temperature rise or long-term temperature rise.For the detailed reasons, they are generally analyzed from the following aspects.1.Electrical power consumption(1) Analysis of power consumption per unit area;(2) Analyze th...
