Double PCBs with red solder mask hot air solder leveling

Double PCBs

Double-sided boards offer a wide variety of possibilities for circuit board designers because they have more surface area and flexibility when routing traces. Using two sides instead of one also allows for a smaller board size overall, which can be important when building small-scale, integrated devices.

A dual sided PCB allows you to have a ground plane or ground grid which is better for reducing electrical noise.

Double Sided PCBs (also known as Double-Sided Plated Thru or DSPT) circuits are the gateway to higher technology applications. They allow for closer (and perhaps more) routing traces by alternating between a top and bottom layer using vias. Today, double sided printed circuit board technology is perhaps the most popular type of PCB in the industry.
