Double Layer PCB

Double Layered printed circuit board technology is conceivably the most popular type of PCB in the industry. Double Sided PCB (also known as Double-Sided Plated Thru or DSPT) circuits are the gateway to advanced technology applications. They allow for a closer (and perhaps more) routing traces by alternating between top and bottom layers using vias.
Benefits of Double Sided PCBs
- More Flexible to Design
- Increased Circuit Compactness
- Relatively Cost-Effective
- Transitional Level of Circuit Density
- Compact Board Size (which can reduce costs)
