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.

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)

Applications of Double Sided PCBs

There are near limitless applications for old and new designs. Fine line surface mount, ultra high copper build, high and low temperature, Solder coated, Silver, and Gold finishes are just a few examples of DSPT applications.

The following are applications in which Double Sided PCBs can be used:

Double sided PCBs are gaining popularity due to several advantages that they offer. These PCBs are becoming regular part of mission critical applications such as industrial controls, power conversion equipment, HVAC, automotive dashboards, etc. Many PCB manufacturers agree that double sided PCB assembly is a complex and time consuming process due to repetition parts on both the sides of the PCB. These manufacturers involve various assembly techniques depending on customer requirements.

  • Industrial controls
  • Power supplies
  • Converters
  • Control relays
  • Instrumentation
  • Regulators
  • UPS systems
  • Power conversion
  • HVAC
  • LED lighting
  • Hard drives
  • Printers
  • Phone systems
  • Power monitoring
  • Automotive dashboards
  • Line reactors
  • Test equipment
  • Amplifiers
  • Traffic systems
  • Vending machines

Double Sided PCBs require plated through holes between the top and bottom pads to provide better anchoring for soldered components. This process and the resultant boards allow interconnections between layers through all holes.And meanwhile, most designs require solder-mask front and back along with a silkscreen layer for component designators.
