Printed circuit board with insulative area for electrostatic discharge damage prevention

Abstract

A printed circuit board for preventing electrostatic discharge damage includes several electronic components thereon. The printed circuit board defines several through holes therein, and includes a signal layer and a ground layer. The signal layer includes a central area and an edge area. The edge area encircles the central area and is separate from the central area. The electronic components are installed on the central area. An insulated area is formed between the central area and the edge area. In a typical application of the printed circuit board, screws are inserted into the through holes and engaged with a panel of a computer enclosure, thereby mounting the printed circuit board to the panel. Thus the edge area is absolutely grounded via the through holes. The electronic components are relatively grounded by connection to the ground layer.
