V4 - Move capacitor to cooler area to improve reliability
C193, a 150uF/16V OSCON capacitor for the +12V (on the primary side of the 3V3, 2V5, 1V8 and 1V2 DC/DC converters), is very close to the inductor L13 that gets relatively hot. L13 is used together with T5 to generate 2.5V.
As temperature can affect the lifetime of this capacitor, it should be moved further to the edge of the board where it is cooler. This will improve the long-term reliability. Note that all DC/DC converters have already a 10uF ceramic capacitor nearby on the primary side that is in parallel to C193.
- Move C193 away from L13 and other inductors to increase reliability.
