6.Using attention
1>.Please make sure all components in right direction and right place.
2>.Please check whether pseudo/float welding.This is very important .
3>.The soldering iron can't touch the components for a long time, otherwise the components will be damaged because of the high temperature.
4>.It is recommended to use a stable power supply, otherwise it may interfere with the audio signal output.
