●Complete PCB
* Compare your PCB with the PCB image below. Check for any unsoldered leads or pins, or any components with insufficient
solder, bridged solder joints between leads/pins or components, and components that may not be fully seated on the PCB.
Check the setting directions of the parts, especially electrolytic capacitors, diodes, IC, FET, etc.
