Layout design should pay attention to the details of the following:

Single panel:

This type of panel is usually used when the cost is low. In the layout design, sometimes the need for components or use jumper to skip the circuit board alignment. If the number is too large, consider using a double panel.

Double panel:

Double panels can be used or can not use PTH. Because the PTH board is expensive, it will be used when the complexity and density of the circuit are needed. In the layout design, the number of wires on the component surface must be kept to a minimum to ensure that the required material is readily available.

In PTH plates, plated through-holes are only used for electrical connection and are not used for component mounting. For economic and reliability reasons, the number of holes should be kept to a minimum.

To select a single panel or a double panel, it is important to take into account the surface area of the component (C), which is a suitable constant ratio to the total area (S) of the printed circuit board. The installation is useful. It is noteworthy that US "usually refers to the area of the panel." Table 3-2 lists the most common printed circuit board S: C ratio range.
