Soldering for beginners.

 Protective measures.
 I many times was scolded by soldering iron, dropped it on my leg, when I rubbed a wire. One day my parrot sat on a hot soldering iron. So, be serious. Remember that your girlfriend or granny may not now about this device.
Put only some flux. It could squirt when you touch it with a soldering iron.
Take soldering iron for 1-2 soldering, surplus can drop and scold you.
 
 Soldering a printed circuit board.
 Printed circuit board can simplify the process of making a radio circuit. All electric connections are lanes from copper foil. Details are securely mounted and are not afraid of vibrations.  We've already told how to make a printed circuit board.
 Mount detail in the needed place on a board and choose the fit depth. Put some flux with a small brush.
 

 Take solder alloy with soldering iron and make sure when you put alloy the soldering tip surface faces the detail and it’s in 45 degrees angle to soldering surface.
 

  If you have good flux and solder alloy, and if the soldering iron is normally heated soldering of one contact takes a second. Good soldering is one without fading, splits and it should shine.
