Double Sided PCBs
Electronic Components Marketing Group
Double sided printed circuit boards (PCBs) are a step up from single sided PCBs in that plated through holes allow for interconnect from layer 1 to layer 2, thus increasing theoretical component density of the PCB. 
Double sided PCBs allow for closer routing traces, making it one of the more popular types of PCBs in the industry.
Double sided PCBs can be used in more advanced devices than single sided PCBs, but aren’t typically found in things like laptops or smartphones. Depending on your device’s needs, a double sided PCB may be the right solution for you. Use the buttons below to request a quote or learn more about your PCB options.
