What are the installation principles of PCB board components?

Recently, many netizens will ask a question: the principle of PCB board component installation. For some PCB novices, this problem is somewhat complicated, and may even be mistaken for something that an expert can understand, but it is not. The installation principles of PCB board components are not as complicated and difficult to understand as everyone thinks. Today we will take a look at what are the installation principles of PCB board components.

1. The components should be laid out inside, and each lead-out of the component should occupy a single pad.
2. The components cannot occupy the entire PCB panel, and a margin of 5~10mm must be left around the board. The size of the PCB board area and the fixing method determine the size of the margin around the board.
3. The components are required to be arranged uniformly and densely on the entire layout.
4. The installation height of the components should be as low as possible. If it is too high, it is easy to fall over or touch adjacent components, which may cause the safety performance of the system to deteriorate.
5. The axial position of the larger components is determined by the installation status of the printed circuit board in the system. The axial direction of the regularly arranged components should be in the vertical direction in the system, so as to improve the stability of the components on the PCB board. sex.
6. The span at both ends of the component should be slightly larger than the axial length of the component. When bending the pins, do not bend them all at once, leave a distance of about 2mm to avoid damaging the components.
7. The layout of components should not cross up and down, and a certain distance should be maintained between adjacent components, and the spacing should not be too small.

Looking at it this way, will you find that the installation principles of PCB board components are actually very simple and easy to understand, but some articles on the Internet will explain it in more detail, hope this article will provide some reference for your PCB research journey .
