Power Distribution -To Route or to Plane PCBs

摘要

POWER DISTRIBUTION ON a PCB can come in a number of forms. The three most common methods are: Route power and ground. Use surface layer floods. Use internal planes. After component positioning, look at power and ground distribution. With a two-layer board, the options are limited to individually routing power and ground, or using a polygon fill, also called a flood or pour (FIGURE 1).
