The circuit board needs to go through a series of processes such as component selection, schematic design, PCB design, circuit board proofing, temperature rise test, etc. to finally produce a circuit board with good performance. Too high temperature rise has a certain impact on the performance and life of the circuit board. The power consumption of components is the direct source of temperature rise. Good adapters makes good performance on temperature rise.In addition to the components, there is also the ambient temperature. Therefore, it is necessary to reduce the internal temperature of the circuit board appropriately. Let APS introduce how to deal with the temperature rise of the circuit board.
1. There are many components in the reasonable design of circuit board layout and wiring circuit board. Each component has different temperature resistance, power consumption and height, so the following factors should be fully considered in the design: for the circuit board environment where there is no cooling system and only relies on air to take away heat, components should be placed correctly and reasonably; For devices sensitive to temperature difference such as thermistors, it is recommended to place them at the lowest temperature; Try not to put the components that are easy to heat together, but evenly distribute them, so as to better heat dissipation.
2. Enlarge the fan cooling system. For some large circuit boards, such as computers, frequency converters, and charging piles, there are usually fan systems. Some will automatically change the wind speed with the temperature.
3. Increase the copper foil area of the circuit board If you want to speed up the heat dissipation, you can increase the copper foil area on the circuit board and place a soldering aid layer. In special cases, you can add tin on the soldering aid layer, so that the heat dissipation effect is better.
4. Adding heat sink and heat dissipation paste The heat sink and heat dissipation paste have good heat conduction effect, which can be added to dissipate heat from switch tubes and other components with severe heat.
5. It is also a good way to select high temperature resistant components and circuit boards. However, it may increase the cost, so it needs to be considered comprehensively. In addition, fiberglass board can be selected.
