Benefits of Double Sided PCBs:
- More flexibility for designers
- Increased circuit density
- Relatively lower costs
- Intermediate level of circuit complexity
- Reduced board size (which can reduce costs)
The double sided “PTH” (plated through holes) PCB is the universal workhorse of the electronics industry. With increasing complexity and density of components many PCB’s need to use both sides of the Printed Circuit Board. This is more usually supplemented with plated-through-holes where the copper connections go right through the connecting holes to the opposite side of the board. These PTH Connections either form simple electrical connection between both sides of the PCB (Via Holes), or electrical connectivity and mechanical support for leaded components. This makes the double sided PTH PCB a much more physically robust item.
