PCB News - Aspects to be considered for PCB board layout

In PCB board design, layout is a very important part. The quality of the system layout will directly affect the effect of the wiring. A reasonable layout can have the following advantages:

· Improve the reliability of the system.

· Make the size of the system smaller;

· Save the space of the circuit board to reduce costs;

Generally speaking, there are two ways of PCB layout, one is interactive PCB layout, and the other is automatic PCB layout. In actual applications, an interactive layout can be used to make adjustments on the basis of automatic layout, and the gate circuits can be redistributed according to the wiring conditions during layout. For example, two gate circuits can be exchanged to make it the best layout for easy wiring.

The success of a product depends on the internal quality and the overall aesthetics. Only when both are perfect can the product be considered successful. Considering the overall beauty of the PCB board layout, on a PCB board, the layout requirements of the components should be balanced, dense and orderly.

Another important issue of PCB board layout is the size of the PCB board. The size of the printed board must match the size of the processing drawings, meet the requirements of the PCB manufacturing process and have positioning marks.

Whether the components of the PCB board conflict in two-dimensional and three-dimensional space must also be considered. For example, thermal elements should be kept away from heat sources.

Some high-power devices in the PCB layout need to add heat sinks, and the size of the heat sinks must also be considered.
