Narrow pattern can cause excessive heat or open circuit.
Chip mounting side
The chip EMI filter suppresses noise by conducting the high-
frequency noise to ground. Therefore, to get enough noise
reduction, feed through holes which are connected to ground-
plane should be arranged according to the figure to reinforce
the ground pattern.
