Single Sided PCBs contain only one layer of conductive material and are best suited for low density designs. Single-sided printed circuit boards are easily designed and quickly manufactured. They serve as the most cost effective platform in the industry.
The PCB was invented to give a good mechanical base for components and by using printing to produce the tracks allowed repeatability of interconnections in volume.
One thin layer of thermally conductive but electrically insulating dielectric is laminated with copper. Solder mask is usually applied on top of the copper.
