Abstract

The invention provides an electronic device comprising an electronic component, a circuit board, a grounding layer and a drive chip. The circuit board comprises a substrate, a patterned line layer and a protective layer, wherein the patterned line layer is allocated on the substrate, and the partial patterned line layer is exposed of the protective layer. At least one grounding pin and a plurality of output / input pins are defined. Each output / input pin comprises a first pointed end, and the length of the grounding pin is larger than that of each output / input pin. The grounding layer covers a part of the protective layer and a part of the grounding pin. The grounding layer comprises a plurality of second pointed ends corresponding to the first pointed ends. A gap is reserved between the forward projection of each first pointed end and the forward projection of each second pointed end. The drive chip is arranged on the circuit board and is in electric connection with the electronic component through the circuit board.

Description

technical field [0001] The present invention relates to an electronic device, and in particular to an electronic device capable of preventing Electro-Static Discharge (ESD) and Electro-Magnetic Interference (EMI). Background technique [0002] Today's electronic products are often equipped with one or more printed circuit boards (Printed Circuit Board, PCB) or flexible circuit boards (Flexible Printed Circuitry, FPC). Generally speaking, one or more electronic components, such as integrated circuits (Integrated Circuit, IC) or passive components, are carried on the circuit board. When the electrostatic discharge (Electro-Static Discharge, ESD) phenomenon occurs, the electronic components will be affected by the sudden large current generated by the electrostatic discharge, causing the system to shut down unexpectedly, or even permanently damaged. [0003] The above electrostatic discharge phenomenon can be roughly divided into human body model (Human Body Model, HBM), mecha...
