	Some components require you put them the correct way around as each end has a different such as ICs. This means the +positive and -negative ends matter. Printed Circuit Boards will indicate which way either by specifying pin 1 or by specifying the polarity.<br>		Some components require you put them the correct way around as each end has a different such as ICs.
