Problems solved by technology

[0004] Before outputting layout-related files, it is necessary to manually check and adjust the placement positions of all component text marks, which reduces the user's work efficiency and is time-consuming and labor-intensive.
In addition, in the process of rushing to work, the user may not be able to confirm the placement position of each component text mark in detail, so that there is still a situation where the component text mark and the via hole placement overlap, and it is also difficult for mass production. affect the appearance of the circuit board

Embodiment Construction

[0015] The present invention will be described in detail below in conjunction with the accompanying drawings.

[0016] see figure 2 , which is a layout method according to an embodiment of the present invention to avoid overlapping placement positions of via holes and component text marks.

[0017] After starting the layout (as shown in step 202 ), it is first determined whether to place vias (as shown in step 204 ). When judging that the via hole is to be placed, a via hole placement operation (as shown in step 208) is performed, and then it is judged whether the placement position of the via hole and the component text mark overlaps (as shown in step 210) ). When it is judged that the placement position of the via hole and the text mark of the component overlaps, it is forbidden to place the via hole at the current position (as shown in step 212), and then correspondingly send a warning message (as shown in step 214), For example, a warning message that the placement pos...

Abstract

The invention provides a layout method for avoiding the overlap of the placing positions of a through hole and an element character mark. The method is characterized in that when a placing operation of the through hole is performed, whether the placing position of the through hole and the placing position of the element character mark overlap or not is determined, and if the placing position of the through hole and the placing position of the element character mark overlap, the through hole is prohibited to be placed in the current position.

Description

technical field [0001] The invention relates to a layout method, in particular to a layout method which can avoid the overlap of placement positions of via holes and component character marks. Background technique [0002] When users use layout (layout) software for printed circuit board (printed circuit board, referred to as PCB) layout, they usually place component text marks (also called silk screen) near the layout position of the components, so that they can be identified in the future. When the circuit board is being debugged, it is convenient for inspectors to find components. [0003] When arranging component text marks, the placement position of vias is usually avoided, so as to avoid damage to component text marks after punching the circuit board according to the placement positions of via holes in the future. However, during the layout process, it is inevitable that the user will accidentally overlap the placement of the component text mark and the via hole, so a...
