In PCB, special components are key components of high -frequency parts, core components in circuits, vulnerable components, high -voltage components, large heat components, and some heterosexual components The positions of these special meta -devices need to be carefully analyzed, and the requirements of the circuit function and the needs of production are made. Inappropriate placing them may have a problem of circuit compatibility and signal integrity, which leads to the failure of PCB design.
When you design special components in design, first consider the size of the PCB size. When the size of the PCB is too large, the printing lines are long, the impedance increases, the anti -drying capacity decreases, and the cost is also increased. After the hour, the heat dissipation is not good, and the nearby lines are easily disturbed. After determining the size of the PCB, determine the position of the special element. Finally, according to the functional unit, all components of the circuit are deployed. The location of the special meta -device generally adheres to the following principles when layout:Solar Energy System
1. Turn the connection between the high -frequency components as much as possible to try to reduce their distributed parameters and electromagnetic interference with each other. Evil and disturbed components cannot be too close to each other, and the input and output should be kept away.
2 Some components or wires may have a high potential difference, and they should increase their distance, so as not to cause short circuit caused by discharge. High -voltage components should be placed as possible where they are not touched.
3. Components weighing more than 15g can be fixed with a bracket and then welded. Those heavy and hot components should not be placed on the circuit board, should be placed on the bottom version of the mainstorbox, and consider the heat dissipation problem. Thermal components should be far away from thermal components.
4. For the layout of adjustable components such as the potentiometer, the adjustable induction coil, the variable capacitor, and the micro -switch, the structure requirements of the entire wrench should be considered. Place it where it is easy to get in touch. The layout of the components is balanced, dense, and cannot be light.
The success of a product is to pay attention to the internal quality. Instead, we must take into account the overall beauty. Both of them are perfect to become a successful product.
