Abstract
The invention relates to a method for processing a lead wire in PCB (Printed Circuit Board) design data, comprising the following steps of: step 1, reading a PCB design data file from a database by CAM (Central Address Memory) software; step 2, inputting the length L and the width W of a required wire section through an operation interface; step 3, utilizing the CAM software to carry out line width analysis on a line layer needing to be processed, so as to obtain each insufficient width position of the lead wire and generating a first wire section at each insufficient width position; step 4, generating a new layer A by utilizing an analyzed result; and step 5, with regard to the first wire section generated at each insufficient width position in the new layer A, respectively converting each first wire section to generate a second wire section with the length of L and the width of W. According to the method for processing the lead wire in the design data, provided by the invention, the wire sections meeting the width requirement can be rapidly generated through automatic calculation, so that the manufacturing time of the lead wire is extremely shortened and the working efficiency is improved.
Description
Technical field
(Printed Circuit Board, PCB) making field relate in particular to the disposal route of the lead in a kind of PCB design data to the present invention relates to printed circuit board (PCB).
Background technology
At present; PCB in manufacturing process, often adopt computer-aided manufacturing (Computer AidedManufacturing, CAM) software is handled the PCB design data; Think that producing each operation provides some work; The for example various films, drilling, gong band etc. are produced thereby reach convenient, play auxiliary manufacturing effect.
When the PCB design data is handled, the minimum widith requirement is generally all arranged for lead (conductor) in the CAM software Genesis 2000 (by the Frontline PCB Solutions company exploitation of Israel) that for example industry is used always.For satisfying the minimum widith requirement of lead, existing disposal route is a manual mode, promptly manually adds the line segment that meets width requirement one by one in the not enough lead location of each width, and this kind mode work efficiency is low, and repeatability is high, and is prone to make mistakes.
Summary of the invention
Therefore, the object of the present invention is to provide the disposal route of the lead in a kind of PCB design data, this disposal route can generate the line segment that satisfies linewidth requirements in the not enough position of each conductor width of each line layer automatically.
For realizing above-mentioned purpose, the present invention provides the disposal route of the lead in a kind of PCB design data, comprises the steps:
Step 4, utilize analysis result to generate new layer A;
Said step 5 specifically comprises: and the starting point coordinate of first line segment that the not enough position of each width is generated among step 5.1, the new layer of the general A (x1, y1) (x2 y2) is stored in the array with terminal point coordinate; Step 5.2, handle as follows: utilize each terminal point coordinate of starting point coordinate of this first line segment to calculate the length L of this first line segment ' for each bar first line segment among the new layer A; According to the length L of calculating ' and the length L of demand calculate the ratio S=L/L ' that this first line segment need stretch; With this first line segment in proportion S prolong; To revolve through first line segment after prolonging then and turn 90 degrees, will become W through the width of postrotational first line segment again, obtain the second corresponding line segment.
In said step 1 and the step 3, CAM The software adopted Genesis 2000.
Beneficial effect of the present invention: the disposal route of the lead in the PCB design data of the present invention; Through automatic calculating; Can generate fast meet that width requirement and length are unified, position line segment accurately; Add the line segment that meets width requirement one by one and need not manual position, thereby greatly shortened the Production Time of lead, improved work efficiency in each width deficiency.
For further setting forth technological means and the effect that the present invention takes for the predetermined purpose of realization; See also following about detailed description of the present invention and accompanying drawing; Believe the object of the invention, characteristic and characteristics; Should obtain thus going deep into and concrete understanding, yet accompanying drawing only provides reference and explanation usefulness, is not to be used for the present invention is limited.
