Printed circuit board, or PCB, is used to mechanically support the electronic components and to connect them electrically using conductive pathways called tracks etched from copper sheets. Besides etched PCBs, there are Common or General purpose PCBs to make temporary or permanent circuits boards. Here explains the types of General purpose PCBs.
Perf
Board
Most experimenters are
familiar with "Perf board" which is a pre-drilled circuit for creating
prototypes of simple circuits. It's not too expensive and for more easier to
get started with than etching PCB's.
The components are mounted by inserting
the leads through the most appropriate holes then are wired on the back side,
usually by bending the leads over to the desired connection point.
