PCB board size
The thickness of the PCB board PCB board function should be based on the weight of the installation components, PCB board socket specifications, PCB board size and shape to withstand mechanical loads, etc. to decide. Principal should ensure sufficient rigidity and strength.
PCB board thickness common are: 0.5mm, 1.0mm, 1.5mm, 2.0mm.
From the cost, the copper film length, noise immunity considerations, PCB board size as small as possible. But the PCB board size is too small, poor heat dissipation, and adjacent wires prone to interference. PCB board production costs and PCB board area is related, the larger the area, the higher the cost. In the design of the cabinet when PCB board has, PCB board size is also limited by the size of the chassis shell must be determined before determining enclosure size PCB board size, otherwise we can not determine the PCB board size. Under normal circumstances, specified in the wiring layer wiring ban PCB board size range is size.
Best PCB board is rectangular in shape, aspect ratio of 3: 2 or 4: 3, when the PCB board size greater than 200 * 150mm, should consider the mechanical strength of the PCB board. In short, we should consider the pros and cons to determine PCB board size.
