Printed circuit board ( PCB ) terminal blocks are specially designed with a copper alloy pin of suitable size and length and can be inserted in printed circuit boards to be soldered to allow electrical signals and current to flow to and from PCBs and electrical equipment.

The practical function is twofold-excluding air and thereby reducing the corrosion of the copper-and ( because lead / tin alloy is so soft and because it flows into the gaps between the conductors ) improving the contact area between the strands and between strands and terminal block.

Using a screw or clip terminal block ( eg http : / / www . amazon . co . uk / Piece-15A-Electrical-Terminal-Block / dp / B000QFCR3C ) might be a simple option-you can get these cheap in any hardware store . talk ) 16 : 25, 31 October 2011 ( UTC)
