Double Sided Circuits

Double sided printed circuit boards are the most widely used of the PCB family. They consist of two (“double”) conductive layers and one layer of solder mask insulating layer on the top and bottom. Standard overall thicknesses range from .031” ‐ .125”. This makes them useful for most electronic applications such as control boards and user interface boards. All component types can be attached to double sided circuits and current carrying capabilities of signal traces range from a few milliamps to several amps.
