PRINTED CIRCUIT BOARD

A PCB(Printed Circuit Board) is provided to enhance the flatness of the PCB by preventing the PCB from being bent and twisted even though the PCB is contracted and expanded for many times. A PCB includes an insulation layer(104), circuit patterns(105,107), and ground plates(101,103). The circuit pat...

Zusammenfassung:	A PCB(Printed Circuit Board) is provided to enhance the flatness of the PCB by preventing the PCB from being bent and twisted even though the PCB is contracted and expanded for many times. A PCB includes an insulation layer(104), circuit patterns(105,107), and ground plates(101,103). The circuit patterns are arranged on the insulation layer. The ground plates are arranged under the insulation layer. Most of the ground plate is divided into more than two sections by a slit-type space. The non-divided section of the ground plate is arranged at a center of a ground surface. The respective divided sections have rectangular shape. The ground surface is divided into four sections by the slit-type space.
