Embodiment Construction

[0018] figure 1 It is a flow chart of a layout method of electromagnetic protection components on a circuit board according to an embodiment of the present invention. figure 2 It is a layout diagram of a circuit board according to an embodiment of the present invention. Please merge reference figure 1 and figure 2 , firstly, in step S101, a layout diagram 200 of a circuit board is provided.

[0019] Next, in step S103 , a “routing outline” function in an Electronic Design Automation (EDA) tool is executed with the first distance d1. In this embodiment, the electronic design automation tool may be "Mentor" layout program or other circuit layout programs, but its scope is not limited. After step S103 is completed, a first geometric line 210 is generated along the edge 230 of the circuit board, and the property of the first geometric line 210 is a wiring boundary, and the distance between the first geometric line 210 and the edge 230 of the circuit board is d1. For example...

Abstract

The invention discloses a layout method of an electromagnetic protection component of a circuit board, comprising the following steps: providing a layout of the circuit board; executing the layout boundary function in the first distance and generating first geometric lines with the attribute being layout boundary along the edge of the circuit board; resetting the attribute of the first geometric lines as layout prevention which can prevent layout operation in the geometry area encircled by the first geometric lines; executing the layout boundary function in the second distance and generating second geometric lines with the attribute being layout boundary along the edge of the circuit board; and carrying out filled layout operation on the circuit board, wherein the layout boundary attribute can prevent layout operation in the geometry area encircled by the second geometric lines.

Description

technical field [0001] The invention relates to a layout method of a circuit board, and in particular to a layout method of electromagnetic protection components of a circuit board. Background technique [0002] With the rapid advancement of technology, modern people's lives benefit from the convenience of electrical products, but they are also in an environment full of electromagnetic waves. Especially for portable electronic products or high-frequency communication products, the electromagnetic radiation of itself is easy to dissipate into the surrounding environment, interfere with adjacent electronic products, and even cause damage to the human body. Therefore, the problem of preventing electromagnetic interference (EMI) has gradually become an important issue. [0003] In circuit design, including wires and circuit boards, electromagnetic radiation will be generated, and electromagnetic radiation will affect the layout lines around the circuit and all conductors that m...
