Embodiment 1

[0051] This embodiment provides a method for setting the font of the silk screen printing on the entire PCB, please refer to figure 1 , the method includes:

[0052] First, step S1 is executed: the fonts of the screen-printed characters are set in advance, and all the fonts of the silk-screened characters are selected as a set.

[0053] Specifically, the skill program can be used to set the optional silk-screen fonts, and the silk-screen fonts can be set according to preset rules and experience, so that the optional silk-screen fonts can cover more than 95% of the silk screen characters.

[0054]Specifically, the silk screen font can be preset through the skill function axlSetParam(), wherein the specific parameters of the font include width, height, line spacing, configuration line width, and character spacing.

[0055] In the specific implementation process, 1-16 groups of screen printing fonts of different sizes can be set through the skill function axlSetParam(), for exam...

Embodiment 2

[0111] This embodiment provides a device for setting fonts for screen printing on the entire PCB, please refer to Figure 6 ,include:

[0112] Silk screen font setting module 601, used to pre-set optional silk screen fonts, all optional silk screen fonts form a set;

[0113] Layer and type acquisition module 602, used to obtain the layer to be set and the silk screen type;

[0114] The target font determination module 603 is used to select the target font from the set of alternative silk-screen fonts according to the layer to be set and the type of silk-screen, as the font of the silk-screen to be set;

[0115] A matching setting module 604, configured to perform matching settings on the silkscreen characters to be set according to the target font.

[0116] In one embodiment, the screen printing font setting module is specifically used for:

[0117] Pre-set the silk screen font through the skill function axlSetParam(), where the specific parameters of the font include width...

Embodiment 3

[0131] This embodiment provides a PCB design system, please refer to Figure 7 , the system includes: EDA software and a SKILL program, wherein the EDA software invokes the SKILL program during execution, and implements the method described in Embodiment 1.

[0132] Specifically, the EDA software may be cadence allegro software, and the configuration method has been described in detail in Embodiment 1, so details are not repeated here.

[0133] Those skilled in the art should understand that the embodiments of the present invention may be provided as methods, systems, or computer program products. Accordingly, the present invention can take the form of an entirely hardware embodiment, an entirely software embodiment, or an embodiment combining software and hardware aspects. Furthermore, the present invention may take the form of a computer program product embodied on one or more computer-usable storage media (including but not limited to disk storage, CD-ROM, optical storage,...

Abstract

The invention provides a Setting method and device for whole PCB silk-screen character fonts and electronic design system, and the method comprises the steps: firstly presetting alternative silk-screen character fonts, and enabling all the alternative silk-screen character fonts to form a set; Then obtaining a to-be-set layer surface and a silk-screen printing type; Selecting a target font from the alternative silk-screen font set as a font of the to-be-set silk-screen font according to the to-be-set level and the silk-screen type; And according to the target font, carrying out matching setting on the to-be-set silk-screen printing character. The technical effect of improving the matching efficiency and accuracy of the silk-screen character fonts is achieved.

Description

technical field [0001] The invention relates to the technical field of non-electronic circuits, in particular to a method, a device and an electronic design system for setting the font size of silk screen printing on the entire PCB. Background technique [0002] There are many kinds of PCB (Printed Circuit Board printed circuit board) design software in the layout (partial diagram) industry. Cadence's allegro software is the most widely used one, which has very rich and powerful functions, and the software also supports Secondary development of software. This software uses a unique data form to store design files, and each design file has a corresponding independent database support. The database mainly contains two types of information: physical information and logical information. Various functional operations in the Allegro software are edits and operations on the information stored in the database. Skill language is an extension language built into the allegro softwar...
