Devices and methods for routing cables through a printed circuit board (PCB) include an enclosure having at least one cable guide and a cable duct. A PCB is mounted in the enclosure, such that the cable duct penetrates the PCB through a hole in the PCB. At least one additional component is mounted in the enclosure and connected to at least one cable that is attached to the at least one cable guide and the cable duct. The at least one cable enters the duct on a first side of the PCB and exits the duct on a second side of the PCB.
