Multilayer 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)
