Little knowledge - Double Sided PCB
Double Sided PCBs also known as Double-Sided Plated Thru or DSPT,
which are the gateway to higher technology applications compared to
single sided PCB.
Double Sided PCB allow for the routing of traces around each other
by jumping between a top and bottom layer by way of vias.
The ability to cross paths from top to bottom greatly increasing
the circuit designer's flexibility in circuits designing and lends
itself to greatly increased circuit densities.
