Abstract

The invention relates to a circuit PCB (printed circuit board). The LED (light-emitting diode) driving circuit PCB (printed circuit board) comprises a PCB substrate, a wire line for driving an LED to work is arranged on the PCB substrate, and an electronic component group for driving the LED to work is welded to the wire line and comprises a driving control chip. The circuit PCB is characterized in that the PCB substrate is two-sided. The two-sided PCB substrate is adopted by the circuit PCB, part of the line can be selectively distributed on the back of the two-sided PCB substrate, and the problem that a single-sided board is limited in area and wiring staggering occurs easily is solved.
