UNLESS OTHERWISE NOTED, this document contains PRODUCTION DATA.
Thermal analysis in this section is focused for the 2-layer and 4-layer PCB with two different copper thickness (1-oz and 2-oz) and six different copper areas (1-cm2, 2-cm2, 4-cm2, 8-cm2, 16-cm2 and 32-cm2).
Figure 140 and Figure 141 shows the top-layer and bottom-layer which is applicable for both 2/4-layer PCB. Figure 142 and Figure 143 shows the mid-layer-1 and mid-layer-2 of a 4-layer PCB. The top-layer, mid-layer-1 and bottom-layer of the PCB is filled with ground plane, whereas, the mid-layer-2 is filled with power plane.
The thickness of copper for different PCB layers in different PCB types is summarized in Table 94. The PCB dimension (A) for different PCB copper area is summarized in Table 95.
