In FIG. 3 and FIG. 4, it can be seen from the pictures of the physical plate that the circuit is relatively dense, and there is a large difference between the ratio of length and width in the engineering design and layout, and the adverse current distribution. The minimum line gap of D/F is 2.8mil (0.070mm), the smallest hole is 0.25mm, the plate thickness is 2.0mm, the aspect ratio is 8:1, and the hole copper is required to be more than 20Um.
