Abstract
A method for manufacturing a printed circuit board of a backlight module is provided. The printed circuit board includes a light bar region and a heat dissipating region. The light bar region used for mounting a light bar of the backlight module and formed with a conductive circuit for supplying power for the light bar. The heat dissipating region is connected with the light bar region. A connection location of the light bar region and the heat dissipating region is subjected to cutting to form a slot located at a side of the printed circuit board in order to prevent short-circuiting between the heat dissipating region and the conductive circuit of the light bar region. The cutting is made to partly penetrate through the thickness of a dielectric layer on which the conductive circuit is formed in order to completely separate the light bar region from the heat dissipating region.
