Embodiment Construction
[0038] The present invention will be further described below in combination with specific embodiments.
[0039] An AutoCAD-based wiring drawing design automation software system according to an embodiment of the present invention, which includes a drawing object definition tool, a text tool, a drawing inspection tool, a drawing report output tool, a chip tool, a layer tool, and a welding tool and graphic publishing tools.
[0040] The drawing object definition tool is used to define the block properties of drawing objects, including chip definition, nip definition, pin definition, and ground coil definition, so as to obtain the lead wire between the chip and the pin.
[0041] The graphic objects include a chip, a pinch of a chip, pins of a frame carrier, and a ground coil, and the block attribute is used to indicate the area where the welding wire falls and the connection relationship between each graphic object.
[0042] The definition of block attributes will be described b...

The invention discloses a wiring drawing design automation software system based on AutoCAD and a design method. The wiring drawing design automation software system comprises a drawing object definition tool, a character tool, a drawing inspection tool, a drawing report output tool, a chip tool, a layer tool, a welding tool and a drawing issuing tool. The design method comprises the following steps: S1, starting an AutoCAD program loaded with a wiring drawing design automation software system; s2, coordinate information of a to-be-drawn chip is obtained; s3, the coordinate information is imported into AutoCAD, and a wireframe chip is generated; s4, performing automatic routing and paging according to the coordinate information; s5, automatically checking the drawing; and S6, drawing design is completed. According to the automatic software system and the design method provided by the invention, the drawing design time consumption is reduced, the wiring drawing design efficiency is improved, the conditions of manual coordinate input errors, wire drawing errors and the like are reduced, and the conditions of wire missing and wire errors during multi-wire identification are reduced.
Description
technical field [0001] The technical field of the semiconductor package design of the present invention, more specifically relates to an AutoCAD-based wiring drawing design automation software system and design method. Background technique [0002] With the continuous development of packaging technology integration, there are more and more pins and bonding wires in traditional packaging wiring drawings. Therefore, the complexity and design risk of product design drawings are getting higher and higher. [0003] The existing design drawing mode is to go to the production line to take photos of the physical chip, or manually draw the wireframe chip in CAD according to the chip coordinates provided by the customer, and then manually pull the wire according to the information provided by the customer, and manually check whether each item of the drawing is correct. Taking photos online consumes a lot of manpower, and improper operations during chip picking can easily damage the ch...
